&lt;br /&gt;
The Mpod-C can be controlled via ethernet, USB, or CAN. For the ethernet, it requires an IP.  &lt;br /&gt;

for &#039;&#039;&#039;R&#039;&#039;&#039;adioactive &#039;&#039;&#039;ION&#039;&#039;&#039; beam). It is a 4π gamma ray detectors array with 16 High-Purity Germanium (HPGe) clover detectors. Each HPGe detector is shied with a BGO (Bismuth Germanate &amp;lt;nowiki&amp;gt;[&amp;lt;/nowiki&amp;gt;Bi4Ge3O12&amp;lt;nowiki&amp;gt;]&amp;lt;/nowiki&amp;gt;) shield. &lt;br /&gt;
&lt;br /&gt;
Each clover detector has 4 crystals, color-coded as Red, Blue, Green, and Black. Here is the angular map for all 16 clovers. Further details of the array can be found [https://doi.org/10.1016/j.nima.2022.167392 here] or [https://arxiv.org/abs/2208.05449 here].&lt;br /&gt;

{{Notice|Solid work model needed}}&lt;br /&gt;
&lt;br /&gt;

[[File:CLARION2 efficiency curve.png|thumb|right|400px|CLARION2 efficiency curve by Tim Gray. The data points are from experimental measurments.]]&lt;br /&gt;
&lt;br /&gt;
The absolute photo-peak efficiency at 1332 keV is ~1.8%.&lt;br /&gt;
&lt;br /&gt;
The equation for the absolute efficiency curve is&lt;br /&gt;
&lt;br /&gt;
&amp;lt;span style=&amp;quot;font-size:120%&amp;quot;&amp;gt;&lt;br /&gt;
&amp;lt;math&amp;gt; \epsilon(e_{\gamma} \text{[keV]}) = \epsilon_0 \exp^{\left( \left(A+Bx + Cx^2\right)^{-G} + \left(D+E y +F y^2\right)^{-G} \right)^{-1/G}}, &amp;lt;/math&amp;gt;&lt;br /&gt;
&amp;lt;/span&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; x = \ln\left(\frac{e_\gamma}{100}\right), y =  \ln\left(\frac{e_\gamma}{1000}\right) &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;

=== GEANT4 simulation ===&lt;br /&gt;
The performance of a single clover detector was simulated using GEANT4. The source code can be downloaded from https://github.com/goluckyryan/HPGeClover.&lt;br /&gt;

== Trinity ==&lt;br /&gt;
[[File:Front view of TRINITY.png|400px|thumb|right|Front view of TRINITY, photo by Vandana.]]&lt;br /&gt;
Trinity is formed by GAGG (&#039;&#039;&#039;G&#039;&#039;&#039;adolinium &#039;&#039;&#039;A&#039;&#039;&#039;luminium &#039;&#039;&#039;G&#039;&#039;&#039;allium &#039;&#039;&#039;G&#039;&#039;&#039;arnet) scintillator crystals. It is located in the target chamber of the Clarion2. The GAGG crystals are arranged in 5 rings, covering 7-54 degrees. Currently only two rings are implemented, which cover 14-24 and 34-44 degrees respectively.&lt;br /&gt;

&lt;br /&gt;
== Neutron Shield ==&lt;br /&gt;
&lt;br /&gt;
In 2022 April, a set of neutron shields surrounded Clarion2 for shielding slow neutrons.&lt;br /&gt;
&lt;br /&gt;
= Clarion2 private network =&lt;br /&gt;
&lt;br /&gt;
The Clarion2 uses its own private network. The network structure is illustrated as following:&lt;br /&gt;
&lt;br /&gt;
 Fox&#039;s Lab network --- clarion2(Mac, gateway) ---- 10 Gb switch&lt;br /&gt;
                                                       +--------- clarion2 DAQ&lt;br /&gt;
                                                       +--------- LN2 control, HV control&lt;br /&gt;
&lt;br /&gt;
= DAQ =&lt;br /&gt;
&lt;br /&gt;
The DAQ system is fully digitized with [[Pixie16 digitizer]]. The signals from the Clover and BGO are directly fed to the Pixie16 digitizers. The data processing library developed by Tim Gray can be found at https://github.com/belmakier/libpixie and https://github.com/belmakier/libClarionTrinity .&lt;br /&gt;
&lt;br /&gt;
The Plx driver was modified from the Broadcom driver. The PixieSDK (legacy) was also modified. &lt;br /&gt;
&lt;br /&gt;
{{Notice | Detail of operation is needed.}}&lt;br /&gt;
&lt;br /&gt;
==Casual Tutorial For Getting a Pixie Crate Up and Running==&lt;br /&gt;
This is meant to be a bit of a tutorial on how to get a Pixie16 crate running from a fresh flash of Ubuntu 18.&lt;br /&gt;
===Prerequisites===&lt;br /&gt;
Make sure that you have at an XIA crate with at least one Rev. F Pixie16 board. Rev. F boards can be recognized by the female headers on the face instead of the male. Rev. D boards have the male, there are several floating around Fox Lab.&lt;br /&gt;
&lt;br /&gt;
Make sure that you have a matching pair of optical communication boards: one to go in the crate and one to go into the PC. These model numbers should match or be close. For example, I had to use a PCI-8331/8336 board in the PC and a PXI-8336 board in the crate. It will not work if there is a mismatch. Trust me.&lt;br /&gt;
&lt;br /&gt;
Make sure you are running Ubuntu 18 with kernel 4.15. The drivers will work with this setup only.&lt;br /&gt;
&lt;br /&gt;
===Installation===&lt;br /&gt;
The install here is a bit of a lie. In your home directory copy the entire ~/pxi/ folder from the Clarion02 DAQ PC. All following instructions are on the local PC.&lt;br /&gt;
&lt;br /&gt;
Navigate to &amp;lt;code&amp;gt; cd ~/pxi/PlxSdk/ &amp;lt;/code&amp;gt;&lt;br /&gt;
Once here give the commands:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;code&amp;gt; make clean &amp;lt;/code&amp;gt;&lt;br /&gt;
&amp;lt;code&amp;gt; make &amp;lt;/code&amp;gt;&lt;br /&gt;
&lt;br /&gt;
This will build a bunch of stuff.&lt;br /&gt;
Next, navigate to the Drivers folder: &amp;lt;code&amp;gt; cd ~/pxi/PlxSdk/Drivers &amp;lt;/code&amp;gt;&lt;br /&gt;
&lt;br /&gt;
I had the most luck with the &amp;quot;builddrivers.sh&amp;quot; script.&lt;br /&gt;
&lt;br /&gt;
Start with the PCI drivers: &amp;lt;code&amp;gt; ./builddrivers Svc &amp;lt;/code&amp;gt;&lt;br /&gt;
&lt;br /&gt;
This will likely throw some errors. If it does find the Dispatch.c script is it complaining about, probably here: ~/pxi/PlxSdk/Driver/PlxSvc/&lt;br /&gt;
&lt;br /&gt;
Edit the includes to look like this:&lt;br /&gt;
&lt;br /&gt;
... I need to find the script so that I can copy the header.... Bad me&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
= LeCroy HV Mainframe=&lt;br /&gt;
The clovers and BGOs bias is supplied by two LeCroy 1458 HV Mainframes. These are controlled via a serial connection to the LN02 PC.&lt;br /&gt;
&lt;br /&gt;
===Clearing Panic Status===&lt;br /&gt;
&lt;br /&gt;
A panic status seems to happen with the loss of power. If the system is in a Panic state, the red LEDs on both sides of the &amp;quot;PANIC OFF&amp;quot; button will be on.&lt;br /&gt;
To clear the Panic status:&lt;br /&gt;
#Turn key to &amp;quot;Local&amp;quot;&lt;br /&gt;
#Press the &amp;quot;HV Off&amp;quot; button. This should clear the status and make the red panic lights go out.&lt;br /&gt;
#TURN THE KEY BACK TO REMOTE!!! This is important so we can control the system via the serial connection.&lt;br /&gt;
&lt;br /&gt;
You will need to do this procedure for each mainframe.&lt;br /&gt;
&lt;br /&gt;
= LN2 cooling system =&lt;br /&gt;
The liquid Nitrogen (LN2) filling system developed by Mitch Allmond (Oak Ridge) is hosted on the LN2-control computer under the account &amp;quot;ln@ln02&amp;quot;.&lt;br /&gt;
=== Changing Alert List ===&lt;br /&gt;
To change the alert list, edit ~/scripts/run-send-alarms.sh with the relevant emails.&lt;br /&gt;
== ln@ln02 Directory==&lt;br /&gt;
Several important directories for using the LN2 system are listed below. &lt;br /&gt;
=== /gln ===&lt;br /&gt;
/gln is the most important directory, it is where the control program is located and for most problems is where you will need to go&lt;br /&gt;
==== gln_ui ====&lt;br /&gt;
gln_ui is the user interface to issue commands to the fill program&lt;br /&gt;

= Introduction =&lt;br /&gt;
Clarion2 &lt;br /&gt;
&amp;lt;ref&amp;gt; T. J. Gray &#039;&#039;et. al&#039;&#039;, NIM A &#039;&#039;&#039;1041&#039;&#039;&#039;, 167392 (2022) https://doi.org/10.1016/j.nima.2022.167392&amp;lt;/ref&amp;gt;&lt;br /&gt;
is the successor of Clarion&lt;br /&gt;
&amp;lt;ref&amp;gt; C. J. Gross &#039;&#039;et. al&#039;&#039;, NIM A &#039;&#039;&#039;450&#039;&#039;&#039;, 12 (2000)  https://doi.org/10.1016/S0168-9002(00)00159-5&amp;lt;/ref&amp;gt;&lt;br /&gt;
(&#039;&#039;&#039;CL&#039;&#039;&#039;over &#039;&#039;&#039;A&#039;&#039;&#039;rray&lt;br /&gt;
for &#039;&#039;&#039;R&#039;&#039;&#039;adioactive &#039;&#039;&#039;ION&#039;&#039;&#039; beam). It is a 4π gamma ray detectors array with 16 High-Purity Germanium (HPGe) clover detectors. Each HPGe detector is shied with a BGO (Bismuth Germanate &amp;lt;nowiki&amp;gt;[&amp;lt;/nowiki&amp;gt;Bi4Ge3O12&amp;lt;nowiki&amp;gt;]&amp;lt;/nowiki&amp;gt;) shield. &lt;br /&gt;
&lt;br /&gt;
Each clover detector has 4 crystals, color-coded as Red, Blue, Green, and Black. Here is the angular map for all 16 clovers. Further details of the array can be found [https://doi.org/10.1016/j.nima.2022.167392 here] or [https://arxiv.org/abs/2208.05449 here].&lt;br /&gt;

&lt;br /&gt;
{{Notice|Solid work model needed}}&lt;br /&gt;
&lt;br /&gt;
== HPGe Clover Detector ==&lt;br /&gt;
The detectors are produced by EURISYS Measure, now CANBERRA, owned by MIRION Technologies &amp;lt;nowiki&amp;gt;[&amp;lt;/nowiki&amp;gt;[https://www.canberra.com/fr/produits/detectors/x-ray-detector-history.html 1]&amp;lt;nowiki&amp;gt;]&amp;lt;/nowiki&amp;gt;. An approximate 3.3 kg clover detector consists of 4 coaxial crystals (dimension 50 mm in diameter, 80 mm in length) &amp;lt;nowiki&amp;gt;[&amp;lt;/nowiki&amp;gt;[https://www.mirion.com/products/clover-detectors-four-coaxial-germanium-detectors Mirion webpage]&amp;lt;nowiki&amp;gt;]&amp;lt;/nowiki&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
=== Typical photon-peak efficiency curve ===&lt;br /&gt;
[[File:CLARION2 efficiency curve.png|thumb|right|400px|CLARION2 efficiency curve by Tim Gray. The data points are from experimental measurments.]]&lt;br /&gt;
&lt;br /&gt;
The absolute photo-peak efficiency at 1332 keV is ~1.8%.&lt;br /&gt;
&lt;br /&gt;
The equation for the absolute efficiency curve is&lt;br /&gt;
&lt;br /&gt;
&amp;lt;span style=&amp;quot;font-size:120%&amp;quot;&amp;gt;&lt;br /&gt;
&amp;lt;math&amp;gt; \epsilon(e_{\gamma} \text{[keV]}) = \epsilon_0 \exp^{\left( \left(A+Bx + Cx^2\right)^{-G} + \left(D+E y +F y^2\right)^{-G} \right)^{-1/G}}, &amp;lt;/math&amp;gt;&lt;br /&gt;
&amp;lt;/span&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; x = \ln\left(\frac{e_\gamma}{100}\right), y =  \ln\left(\frac{e_\gamma}{1000}\right) &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; \epsilon_0 = 0.0037679 &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; A = 13.6858 &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; B = 1.4055 &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; C = 0.000 &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; D = 3.8942 &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; E = -2.4073 &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; F = 0.0629 &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; G = 0.5000 &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
=== GEANT4 simulation ===&lt;br /&gt;
The performance of a single clover detector was simulated using GEANT4. The source code can be downloaded from https://github.com/goluckyryan/HPGeClover.&lt;br /&gt;
&lt;br /&gt;
[[File:GEAN4 simulation of 152Eu.png|600px|thumb|none|GEANT4 simulation of 152Eu]]&lt;br /&gt;
&lt;br /&gt;
A GEANT4 simulation for Clarion2 can be found at https://fsunuc.physics.fsu.edu/git/pderosa888/CLARION2_GEANT4. Please ask Raeed Nawaf for an updated model here: rn24b@fsu.edu&lt;br /&gt;

== Trinity ==&lt;br /&gt;
[[File:Front view of TRINITY.png|400px|thumb|right|Front view of TRINITY, photo by Vandana.]]&lt;br /&gt;
Trinity is formed by GAGG (&#039;&#039;&#039;G&#039;&#039;&#039;adolinium &#039;&#039;&#039;A&#039;&#039;&#039;luminium &#039;&#039;&#039;G&#039;&#039;&#039;allium &#039;&#039;&#039;G&#039;&#039;&#039;arnet) scintillator crystals. It is located in the target chamber of the Clarion2. The GAGG crystals are arranged in 5 rings, covering 7-54 degrees. Currently only two rings are implemented, which cover 14-24 and 34-44 degrees respectively.&lt;br /&gt;
&lt;br /&gt;

&lt;br /&gt;
== Neutron Shield ==&lt;br /&gt;
&lt;br /&gt;
In 2022 April, a set of neutron shields surrounded Clarion2 for shielding slow neutrons.&lt;br /&gt;
&lt;br /&gt;
= Clarion2 private network =&lt;br /&gt;
&lt;br /&gt;
The Clarion2 uses its own private network. The network structure is illustrated as following:&lt;br /&gt;
&lt;br /&gt;
 Fox&#039;s Lab network --- clarion2(Mac, gateway) ---- 10 Gb switch&lt;br /&gt;
                                                       +--------- clarion2 DAQ&lt;br /&gt;
                                                       +--------- LN2 control, HV control&lt;br /&gt;
&lt;br /&gt;
= DAQ =&lt;br /&gt;
&lt;br /&gt;
The DAQ system is fully digitized with [[Pixie16 digitizer]]. The signals from the Clover and BGO are directly fed to the Pixie16 digitizers. The data processing library developed by Tim Gray can be found at https://github.com/belmakier/libpixie and https://github.com/belmakier/libClarionTrinity .&lt;br /&gt;
&lt;br /&gt;
The Plx driver was modified from the Broadcom driver. The PixieSDK (legacy) was also modified. &lt;br /&gt;
&lt;br /&gt;
{{Notice | Detail of operation is needed.}}&lt;br /&gt;
&lt;br /&gt;
= LeCroy HV Mainframe=&lt;br /&gt;
The clovers and BGOs bias is supplied by two LeCroy 1458 HV Mainframes. These are controlled via a serial connection to the LN02 PC.&lt;br /&gt;
&lt;br /&gt;
===Clearing Panic Status===&lt;br /&gt;
&lt;br /&gt;
A panic status seems to happen with the loss of power. If the system is in a Panic state, the red LEDs on both sides of the &amp;quot;PANIC OFF&amp;quot; button will be on.&lt;br /&gt;
To clear the Panic status:&lt;br /&gt;
#Turn key to &amp;quot;Local&amp;quot;&lt;br /&gt;
#Press the &amp;quot;HV Off&amp;quot; button. This should clear the status and make the red panic lights go out.&lt;br /&gt;
#TURN THE KEY BACK TO REMOTE!!! This is important so we can control the system via the serial connection.&lt;br /&gt;
&lt;br /&gt;
You will need to do this procedure for each mainframe.&lt;br /&gt;
&lt;br /&gt;
= LN2 cooling system =&lt;br /&gt;
The liquid Nitrogen (LN2) filling system developed by Mitch Allmond (Oak Ridge) is hosted on the LN2-control computer under the account &amp;quot;ln@ln02&amp;quot;.&lt;br /&gt;
=== Changing Alert List ===&lt;br /&gt;
To change the alert list, edit ~/scripts/run-send-alarms.sh with the relevant emails.&lt;br /&gt;
== ln@ln02 Directory==&lt;br /&gt;
Several important directories for using the LN2 system are listed below. &lt;br /&gt;
=== /gln ===&lt;br /&gt;
/gln is the most important directory, it is where the control program is located and for most problems is where you will need to go&lt;br /&gt;
==== gln_ui ====&lt;br /&gt;
gln_ui is the user interface to issue commands to the fill program&lt;br /&gt;
&amp;lt;div class=&amp;quot;toccolours mw-collapsible mw-collapsed&amp;quot;&amp;gt;&lt;br /&gt;
&amp;lt;div style=&amp;quot;line-height:1.6;&amp;quot;&amp;gt;gln_ui Commands&amp;lt;/div&amp;gt;&lt;br /&gt;

= Introduction =&lt;br /&gt;
Clarion2 &lt;br /&gt;
&amp;lt;ref&amp;gt; T. J. Gray &#039;&#039;et. al&#039;&#039;, NIM A &#039;&#039;&#039;1041&#039;&#039;&#039;, 167392 (2022) https://doi.org/10.1016/j.nima.2022.167392&amp;lt;/ref&amp;gt;&lt;br /&gt;
is the successor of Clarion&lt;br /&gt;
&amp;lt;ref&amp;gt; C. J. Gross &#039;&#039;et. al&#039;&#039;, NIM A &#039;&#039;&#039;450&#039;&#039;&#039;, 12 (2000)  https://doi.org/10.1016/S0168-9002(00)00159-5&amp;lt;/ref&amp;gt;&lt;br /&gt;
(&#039;&#039;&#039;CL&#039;&#039;&#039;over &#039;&#039;&#039;A&#039;&#039;&#039;rray&lt;br /&gt;
for &#039;&#039;&#039;R&#039;&#039;&#039;adioactive &#039;&#039;&#039;ION&#039;&#039;&#039; beam). It is a 4π gamma ray detectors array with 16 High-Purity Germanium (HPGe) clover detectors. Each HPGe detector is shied with a BGO (Bismuth Germanate &amp;lt;nowiki&amp;gt;[&amp;lt;/nowiki&amp;gt;Bi4Ge3O12&amp;lt;nowiki&amp;gt;]&amp;lt;/nowiki&amp;gt;) shield. &lt;br /&gt;
&lt;br /&gt;
Each clover detector has 4 crystals, color-coded as Red, Blue, Green, and Black. Here is the angular map for all 16 clovers. Further details of the array can be found [https://doi.org/10.1016/j.nima.2022.167392 here] or [https://arxiv.org/abs/2208.05449 here].&lt;br /&gt;

[[File:Clarion2 angular map.png|400px|thumb|none|Clarion2 angular map. The purple dot is the center of each clover.]]&lt;br /&gt;
&lt;br /&gt;
{{Notice|Solid work model needed}}&lt;br /&gt;
&lt;br /&gt;
== HPGe Clover Detector ==&lt;br /&gt;
The detectors are produced by EURISYS Measure, now CANBERRA, owned by MIRION Technologies &amp;lt;nowiki&amp;gt;[&amp;lt;/nowiki&amp;gt;[https://www.canberra.com/fr/produits/detectors/x-ray-detector-history.html 1]&amp;lt;nowiki&amp;gt;]&amp;lt;/nowiki&amp;gt;. An approximate 3.3 kg clover detector consists of 4 coaxial crystals (dimension 50 mm in diameter, 80 mm in length) &amp;lt;nowiki&amp;gt;[&amp;lt;/nowiki&amp;gt;[https://www.mirion.com/products/clover-detectors-four-coaxial-germanium-detectors Mirion webpage]&amp;lt;nowiki&amp;gt;]&amp;lt;/nowiki&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
=== Typical photon-peak efficiency curve ===&lt;br /&gt;
[[File:CLARION2 efficiency curve.png|thumb|right|400px|CLARION2 efficiency curve by Tim Gray. The data points are from experimental measurments.]]&lt;br /&gt;
&lt;br /&gt;
The absolute photo-peak efficiency at 1332 keV is ~1.8%.&lt;br /&gt;
&lt;br /&gt;
The equation for the absolute efficiency curve is&lt;br /&gt;
&lt;br /&gt;
&amp;lt;span style=&amp;quot;font-size:120%&amp;quot;&amp;gt;&lt;br /&gt;
&amp;lt;math&amp;gt; \epsilon(e_{\gamma} \text{[keV]}) = \epsilon_0 \exp^{\left( \left(A+Bx + Cx^2\right)^{-G} + \left(D+E y +F y^2\right)^{-G} \right)^{-1/G}}, &amp;lt;/math&amp;gt;&lt;br /&gt;
&amp;lt;/span&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; x = \ln\left(\frac{e_\gamma}{100}\right), y =  \ln\left(\frac{e_\gamma}{1000}\right) &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; \epsilon_0 = 0.0037679 &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; A = 13.6858 &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; B = 1.4055 &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; C = 0.000 &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; D = 3.8942 &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; E = -2.4073 &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; F = 0.0629 &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; G = 0.5000 &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
=== GEANT4 simulation ===&lt;br /&gt;
The performance of a single clover detector was simulated using GEANT4. The source code can be downloaded from https://github.com/goluckyryan/HPGeClover.&lt;br /&gt;
&lt;br /&gt;
[[File:GEAN4 simulation of 152Eu.png|600px|thumb|none|GEANT4 simulation of 152Eu]]&lt;br /&gt;
&lt;br /&gt;
A GEANT4 simulation for Clarion2 can be found at https://fsunuc.physics.fsu.edu/git/pderosa888/CLARION2_GEANT4.&lt;br /&gt;

== Trinity ==&lt;br /&gt;
[[File:Front view of TRINITY.png|400px|thumb|right|Front view of TRINITY, photo by Vandana.]]&lt;br /&gt;
Trinity is formed by GAGG (&#039;&#039;&#039;G&#039;&#039;&#039;adolinium &#039;&#039;&#039;A&#039;&#039;&#039;luminium &#039;&#039;&#039;G&#039;&#039;&#039;allium &#039;&#039;&#039;G&#039;&#039;&#039;arnet) scintillator crystals. It is located in the target chamber of the Clarion2. The GAGG crystals are arranged in 5 rings, covering 7-54 degrees. Currently only two rings are implemented, which cover 14-24 and 34-44 degrees respectively.&lt;br /&gt;
&lt;br /&gt;

&lt;br /&gt;
== Neutron Shield ==&lt;br /&gt;
&lt;br /&gt;
In 2022 April, a set of neutron shields surrounded Clarion2 for shielding slow neutrons.&lt;br /&gt;
&lt;br /&gt;
= Clarion2 private network =&lt;br /&gt;
&lt;br /&gt;
The Clarion2 uses its own private network. The network structure is illustrated as following:&lt;br /&gt;
&lt;br /&gt;
 Fox&#039;s Lab network --- clarion2(Mac, gateway) ---- 10 Gb switch&lt;br /&gt;
                                                       +--------- clarion2 DAQ&lt;br /&gt;
                                                       +--------- LN2 control, HV control&lt;br /&gt;
&lt;br /&gt;
= DAQ =&lt;br /&gt;
&lt;br /&gt;
The DAQ system is fully digitized with [[Pixie16 digitizer]]. The signals from the Clover and BGO are directly fed to the Pixie16 digitizers. The data processing library developed by Tim Gray can be found at https://github.com/belmakier/libpixie and https://github.com/belmakier/libClarionTrinity .&lt;br /&gt;
&lt;br /&gt;
The Plx driver was modified from the Broadcom driver. The PixieSDK (legacy) was also modified. &lt;br /&gt;
&lt;br /&gt;
{{Notice | Detail of operation is needed.}}&lt;br /&gt;
&lt;br /&gt;
= LeCroy HV Mainframe=&lt;br /&gt;
The clovers and BGOs bias is supplied by two LeCroy 1458 HV Mainframes. These are controlled via a serial connection to the LN02 PC.&lt;br /&gt;
&lt;br /&gt;
===Clearing Panic Status===&lt;br /&gt;
&lt;br /&gt;
A panic status seems to happen with the loss of power. If the system is in a Panic state, the red LEDs on both sides of the &amp;quot;PANIC OFF&amp;quot; button will be on.&lt;br /&gt;
To clear the Panic status:&lt;br /&gt;
#Turn key to &amp;quot;Local&amp;quot;&lt;br /&gt;
#Press the &amp;quot;HV Off&amp;quot; button. This should clear the status and make the red panic lights go out.&lt;br /&gt;
#TURN THE KEY BACK TO REMOTE!!! This is important so we can control the system via the serial connection.&lt;br /&gt;
&lt;br /&gt;
You will need to do this procedure for each mainframe.&lt;br /&gt;
&lt;br /&gt;
= LN2 cooling system =&lt;br /&gt;
The liquid Nitrogen (LN2) filling system developed by Mitch Allmond (Oak Ridge) is hosted on the LN2-control computer under the account &amp;quot;ln@ln02&amp;quot;.&lt;br /&gt;
=== Changing Alert List ===&lt;br /&gt;
To change the alert list, edit ~/scripts/run-send-alarms.sh with the relevant emails.&lt;br /&gt;
== ln@ln02 Directory==&lt;br /&gt;
Several important directories for using the LN2 system are listed below. &lt;br /&gt;
=== /gln ===&lt;br /&gt;
/gln is the most important directory, it is where the control program is located and for most problems is where you will need to go&lt;br /&gt;
==== gln_ui ====&lt;br /&gt;
gln_ui is the user interface to issue commands to the fill program&lt;br /&gt;
&amp;lt;div class=&amp;quot;toccolours mw-collapsible mw-collapsed&amp;quot;&amp;gt;&lt;br /&gt;
&amp;lt;div style=&amp;quot;line-height:1.6;&amp;quot;&amp;gt;gln_ui Commands&amp;lt;/div&amp;gt;&lt;br /&gt;
&amp;lt;div class=&amp;quot;mw-collapsible-content&amp;quot;&amp;gt;&lt;br /&gt;

= Introduction =&lt;br /&gt;
Clarion2 &lt;br /&gt;
&amp;lt;ref&amp;gt; T. J. Gray &#039;&#039;et. al&#039;&#039;, NIM A &#039;&#039;&#039;1041&#039;&#039;&#039;, 167392 (2022) https://doi.org/10.1016/j.nima.2022.167392&amp;lt;/ref&amp;gt;&lt;br /&gt;
is the successor of Clarion&lt;br /&gt;
&amp;lt;ref&amp;gt; C. J. Gross &#039;&#039;et. al&#039;&#039;, NIM A &#039;&#039;&#039;450&#039;&#039;&#039;, 12 (2000)  https://doi.org/10.1016/S0168-9002(00)00159-5&amp;lt;/ref&amp;gt;&lt;br /&gt;
(&#039;&#039;&#039;CL&#039;&#039;&#039;over &#039;&#039;&#039;A&#039;&#039;&#039;rray&lt;br /&gt;
for &#039;&#039;&#039;R&#039;&#039;&#039;adioactive &#039;&#039;&#039;ION&#039;&#039;&#039; beam). It is a 4π gamma ray detectors array with 16 High-Purity Germanium (HPGe) clover detectors. Each HPGe detector is shied with a BGO (Bismuth Germanate &amp;lt;nowiki&amp;gt;[&amp;lt;/nowiki&amp;gt;Bi4Ge3O12&amp;lt;nowiki&amp;gt;]&amp;lt;/nowiki&amp;gt;) shield. &lt;br /&gt;
&lt;br /&gt;
Each clover detector has 4 crystals, color-coded as Red, Blue, Green, and Black. Here is the angular map for all 16 clovers. Further details of the array can be found [https://doi.org/10.1016/j.nima.2022.167392 here] or [https://arxiv.org/abs/2208.05449 here].&lt;br /&gt;
&lt;br /&gt;
[[File:Clarion2 angular map.png|400px|thumb|none|Clarion2 angular map. The purple dot is the center of each clover.]]&lt;br /&gt;
&lt;br /&gt;
{{Notice|Solid work model needed}}&lt;br /&gt;
&lt;br /&gt;
== HPGe Clover Detector ==&lt;br /&gt;
The detectors are produced by EURISYS Measure, now CANBERRA, owned by MIRION Technologies &amp;lt;nowiki&amp;gt;[&amp;lt;/nowiki&amp;gt;[https://www.canberra.com/fr/produits/detectors/x-ray-detector-history.html 1]&amp;lt;nowiki&amp;gt;]&amp;lt;/nowiki&amp;gt;. An approximate 3.3 kg clover detector consists of 4 coaxial crystals (dimension 50 mm in diameter, 80 mm in length) &amp;lt;nowiki&amp;gt;[&amp;lt;/nowiki&amp;gt;[https://www.mirion.com/products/clover-detectors-four-coaxial-germanium-detectors Mirion webpage]&amp;lt;nowiki&amp;gt;]&amp;lt;/nowiki&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
=== Typical photon-peak efficiency curve ===&lt;br /&gt;
[[File:CLARION2 efficiency curve.png|thumb|right|400px|CLARION2 efficiency curve by Tim Gray. The data points are from experimental measurments.]]&lt;br /&gt;
&lt;br /&gt;
The absolute photo-peak efficiency at 1332 keV is ~1.8%.&lt;br /&gt;
&lt;br /&gt;
The equation for the absolute efficiency curve is&lt;br /&gt;
&lt;br /&gt;
&amp;lt;span style=&amp;quot;font-size:120%&amp;quot;&amp;gt;&lt;br /&gt;
&amp;lt;math&amp;gt; \epsilon(e_{\gamma} \text{[keV]}) = \epsilon_0 \exp^{\left( \left(A+Bx + Cx^2\right)^{-G} + \left(D+E y +F y^2\right)^{-G} \right)^{-1/G}}, &amp;lt;/math&amp;gt;&lt;br /&gt;
&amp;lt;/span&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; x = \ln\left(\frac{e_\gamma}{100}\right), y =  \ln\left(\frac{e_\gamma}{1000}\right) &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; \epsilon_0 = 0.0037679 &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; A = 13.6858 &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; B = 1.4055 &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; C = 0.000 &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; D = 3.8942 &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; E = -2.4073 &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; F = 0.0629 &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; G = 0.5000 &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
=== GEANT4 simulation ===&lt;br /&gt;
The performance of a single clover detector was simulated using GEANT4. The source code can be downloaded from https://github.com/goluckyryan/HPGeClover.&lt;br /&gt;
&lt;br /&gt;
[[File:GEAN4 simulation of 152Eu.png|600px|thumb|none|GEANT4 simulation of 152Eu]]&lt;br /&gt;
&lt;br /&gt;
A GEANT4 simulation for Clarion2 can be found at https://fsunuc.physics.fsu.edu/git/pderosa888/CLARION2_GEANT4.&lt;br /&gt;
&lt;br /&gt;

&lt;br /&gt;
== Trinity ==&lt;br /&gt;
[[File:Front view of TRINITY.png|400px|thumb|right|Front view of TRINITY, photo by Vandana.]]&lt;br /&gt;
Trinity is formed by GAGG (&#039;&#039;&#039;G&#039;&#039;&#039;adolinium &#039;&#039;&#039;A&#039;&#039;&#039;luminium &#039;&#039;&#039;G&#039;&#039;&#039;allium &#039;&#039;&#039;G&#039;&#039;&#039;arnet) scintillator crystals. It is located in the target chamber of the Clarion2. The GAGG crystals are arranged in 5 rings, covering 7-54 degrees. Currently only two rings are implemented, which cover 14-24 and 34-44 degrees respectively.&lt;br /&gt;
&lt;br /&gt;

&lt;br /&gt;
== Neutron Shield ==&lt;br /&gt;
&lt;br /&gt;
In 2022 April, a set of neutron shields surrounded Clarion2 for shielding slow neutrons.&lt;br /&gt;
&lt;br /&gt;
= Clarion2 private network =&lt;br /&gt;
&lt;br /&gt;
The Clarion2 uses its own private network. The network structure is illustrated as following:&lt;br /&gt;
&lt;br /&gt;
 Fox&#039;s Lab network --- clarion2(Mac, gateway) ---- 10 Gb switch&lt;br /&gt;
                                                       +--------- clarion2 DAQ&lt;br /&gt;
                                                       +--------- LN2 control, HV control&lt;br /&gt;
&lt;br /&gt;
= DAQ =&lt;br /&gt;
&lt;br /&gt;
The DAQ system is fully digitized with [[Pixie16 digitizer]]. The signals from the Clover and BGO are directly fed to the Pixie16 digitizers. The data processing library developed by Tim Gray can be found at https://github.com/belmakier/libpixie and https://github.com/belmakier/libClarionTrinity .&lt;br /&gt;
&lt;br /&gt;
The Plx driver was modified from the Broadcom driver. The PixieSDK (legacy) was also modified. &lt;br /&gt;
&lt;br /&gt;
{{Notice | Detail of operation is needed.}}&lt;br /&gt;
&lt;br /&gt;
= LeCroy HV Mainframe=&lt;br /&gt;
The clovers and BGOs bias is supplied by two LeCroy 1458 HV Mainframes. These are controlled via a serial connection to the LN02 PC.&lt;br /&gt;
&lt;br /&gt;
===Clearing Panic Status===&lt;br /&gt;
&lt;br /&gt;
A panic status seems to happen with the loss of power. If the system is in a Panic state, the red LEDs on both sides of the &amp;quot;PANIC OFF&amp;quot; button will be on.&lt;br /&gt;
To clear the Panic status:&lt;br /&gt;
#Turn key to &amp;quot;Local&amp;quot;&lt;br /&gt;
#Press the &amp;quot;HV Off&amp;quot; button. This should clear the status and make the red panic lights go out.&lt;br /&gt;
#TURN THE KEY BACK TO REMOTE!!! This is important so we can control the system via the serial connection.&lt;br /&gt;
&lt;br /&gt;
You will need to do this procedure for each mainframe.&lt;br /&gt;
&lt;br /&gt;
= LN2 cooling system =&lt;br /&gt;
The liquid Nitrogen (LN2) filling system developed by Mitch Allmond (Oak Ridge) is hosted on the LN2-control computer under the account &amp;quot;ln@ln02&amp;quot;.&lt;br /&gt;
=== Changing Alert List ===&lt;br /&gt;
To change the alert list, edit ~/scripts/run-send-alarms.sh with the relevant emails.&lt;br /&gt;
== ln@ln02 Directory==&lt;br /&gt;
Several important directories for using the LN2 system are listed below. &lt;br /&gt;
=== /gln ===&lt;br /&gt;
/gln is the most important directory, it is where the control program is located and for most problems is where you will need to go&lt;br /&gt;
==== gln_ui ====&lt;br /&gt;
gln_ui is the user interface to issue commands to the fill program&lt;br /&gt;
&amp;lt;div class=&amp;quot;toccolours mw-collapsible mw-collapsed&amp;quot;&amp;gt;&lt;br /&gt;
&amp;lt;div style=&amp;quot;line-height:1.6;&amp;quot;&amp;gt;gln_ui Commands&amp;lt;/div&amp;gt;&lt;br /&gt;
&amp;lt;div class=&amp;quot;mw-collapsible-content&amp;quot;&amp;gt;&lt;br /&gt;
--------------------------------------&lt;br /&gt;

for &#039;&#039;&#039;R&#039;&#039;&#039;adioactive &#039;&#039;&#039;ION&#039;&#039;&#039; beam). It is a 4π gamma ray detectors array with 16 High-Purity Germanium (HPGe) clover detectors. Each HPGe detector is shied with a BGO (Bismuth Germanate &amp;lt;nowiki&amp;gt;[&amp;lt;/nowiki&amp;gt;Bi4Ge3O12&amp;lt;nowiki&amp;gt;]&amp;lt;/nowiki&amp;gt;) shield. &lt;br /&gt;
&lt;br /&gt;
Each clover detector has 4 crystals, color-coded as Red, Blue, Green, and Black. Here is the angular map for all 16 clovers. Further details of the array can be found [https://doi.org/10.1016/j.nima.2022.167392 here] or [https://arxiv.org/abs/2208.05449 here].&lt;br /&gt;

{{Notice|Solid work model needed}}&lt;br /&gt;
&lt;br /&gt;
== HPGe Clover Detector ==&lt;br /&gt;
The detectors are produced by EURISYS Measure, now CANBERRA, owned by MIRION Technologies &amp;lt;nowiki&amp;gt;[&amp;lt;/nowiki&amp;gt;[https://www.canberra.com/fr/produits/detectors/x-ray-detector-history.html 1]&amp;lt;nowiki&amp;gt;]&amp;lt;/nowiki&amp;gt;. An approximate 3.3 kg clover detector consists of 4 coaxial crystals (dimension 50 mm in diameter, 80 mm in length) &amp;lt;nowiki&amp;gt;[&amp;lt;/nowiki&amp;gt;[https://www.mirion.com/products/clover-detectors-four-coaxial-germanium-detectors Mirion webpage]&amp;lt;nowiki&amp;gt;]&amp;lt;/nowiki&amp;gt;.&lt;br /&gt;

=== Typical photon-peak efficiency curve ===&lt;br /&gt;
[[File:CLARION2 efficiency curve.png|thumb|right|400px|CLARION2 efficiency curve by Tim Gray. The data points are from experimental measurments.]]&lt;br /&gt;
&lt;br /&gt;
The absolute photo-peak efficiency at 1332 keV is ~1.8%.&lt;br /&gt;
&lt;br /&gt;
The equation for the absolute efficiency curve is&lt;br /&gt;
&lt;br /&gt;
&amp;lt;span style=&amp;quot;font-size:120%&amp;quot;&amp;gt;&lt;br /&gt;
&amp;lt;math&amp;gt; \epsilon(e_{\gamma} \text{[keV]}) = \epsilon_0 \exp^{\left( \left(A+Bx + Cx^2\right)^{-G} + \left(D+E y +F y^2\right)^{-G} \right)^{-1/G}}, &amp;lt;/math&amp;gt;&lt;br /&gt;
&amp;lt;/span&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; x = \ln\left(\frac{e_\gamma}{100}\right), y =  \ln\left(\frac{e_\gamma}{1000}\right) &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; \epsilon_0 = 0.0037679 &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; A = 13.6858 &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; B = 1.4055 &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; C = 0.000 &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; D = 3.8942 &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; E = -2.4073 &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; F = 0.0629 &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; G = 0.5000 &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
=== GEANT4 simulation ===&lt;br /&gt;
The performance of a single clover detector was simulated using GEANT4. The source code can be downloaded from https://github.com/goluckyryan/HPGeClover.&lt;br /&gt;
&lt;br /&gt;

&lt;br /&gt;
== Trinity ==&lt;br /&gt;
[[File:Front view of TRINITY.png|400px|thumb|right|Front view of TRINITY, photo by Vandana.]]&lt;br /&gt;
Trinity is formed by GAGG (&#039;&#039;&#039;G&#039;&#039;&#039;adolinium &#039;&#039;&#039;A&#039;&#039;&#039;luminium &#039;&#039;&#039;G&#039;&#039;&#039;allium &#039;&#039;&#039;G&#039;&#039;&#039;arnet) scintillator crystals. It is located in the target chamber of the Clarion2. The GAGG crystals are arranged in 5 rings, covering 7-54 degrees. Currently only two rings are implemented, which cover 14-24 and 34-44 degrees respectively.&lt;br /&gt;
&lt;br /&gt;
[[File:A single GAGG detector.png|400px|thumb|none|A single GAGG detector]]&lt;br /&gt;
&lt;br /&gt;
== Neutron Shield ==&lt;br /&gt;
&lt;br /&gt;
In 2022 April, a set of neutron shields surrounded Clarion2 for shielding slow neutrons.&lt;br /&gt;
&lt;br /&gt;
= Clarion2 private network =&lt;br /&gt;
&lt;br /&gt;
The Clarion2 uses its own private network. The network structure is illustrated as following:&lt;br /&gt;
&lt;br /&gt;
 Fox&#039;s Lab network --- clarion2(Mac, gateway) ---- 10 Gb switch&lt;br /&gt;
                                                       +--------- clarion2 DAQ&lt;br /&gt;
                                                       +--------- LN2 control, HV control&lt;br /&gt;
&lt;br /&gt;
= DAQ =&lt;br /&gt;
&lt;br /&gt;
The DAQ system is fully digitized with [[Pixie16 digitizer]]. The signals from the Clover and BGO are directly fed to the Pixie16 digitizers. The data processing library developed by Tim Gray can be found at https://github.com/belmakier/libpixie and https://github.com/belmakier/libClarionTrinity .&lt;br /&gt;
&lt;br /&gt;
The Plx driver was modified from the Broadcom driver. The PixieSDK (legacy) was also modified. &lt;br /&gt;
&lt;br /&gt;
{{Notice | Detail of operation is needed.}}&lt;br /&gt;
&lt;br /&gt;
= LeCroy HV Mainframe=&lt;br /&gt;
The clovers and BGOs bias is supplied by two LeCroy 1458 HV Mainframes. These are controlled via a serial connection to the LN02 PC.&lt;br /&gt;
&lt;br /&gt;
===Clearing Panic Status===&lt;br /&gt;
&lt;br /&gt;
A panic status seems to happen with the loss of power. If the system is in a Panic state, the red LEDs on both sides of the &amp;quot;PANIC OFF&amp;quot; button will be on.&lt;br /&gt;
To clear the Panic status:&lt;br /&gt;
#Turn key to &amp;quot;Local&amp;quot;&lt;br /&gt;
#Press the &amp;quot;HV Off&amp;quot; button. This should clear the status and make the red panic lights go out.&lt;br /&gt;
#TURN THE KEY BACK TO REMOTE!!! This is important so we can control the system via the serial connection.&lt;br /&gt;
&lt;br /&gt;
You will need to do this procedure for each mainframe.&lt;br /&gt;
&lt;br /&gt;
= LN2 cooling system =&lt;br /&gt;
The liquid Nitrogen (LN2) filling system developed by Mitch Allmond (Oak Ridge) is hosted on the LN2-control computer under the account &amp;quot;ln@ln02&amp;quot;.&lt;br /&gt;
=== Changing Alert List ===&lt;br /&gt;
To change the alert list, edit ~/scripts/run-send-alarms.sh with the relevant emails.&lt;br /&gt;
== ln@ln02 Directory==&lt;br /&gt;
Several important directories for using the LN2 system are listed below. &lt;br /&gt;
=== /gln ===&lt;br /&gt;
/gln is the most important directory, it is where the control program is located and for most problems is where you will need to go&lt;br /&gt;
==== gln_ui ====&lt;br /&gt;
gln_ui is the user interface to issue commands to the fill program&lt;br /&gt;
&amp;lt;div class=&amp;quot;toccolours mw-collapsible mw-collapsed&amp;quot;&amp;gt;&lt;br /&gt;
&amp;lt;div style=&amp;quot;line-height:1.6;&amp;quot;&amp;gt;gln_ui Commands&amp;lt;/div&amp;gt;&lt;br /&gt;

for &#039;&#039;&#039;R&#039;&#039;&#039;adioactive &#039;&#039;&#039;ION&#039;&#039;&#039; beam). It is a 4π gamma ray detectors array with 16 High-Purity Germanium (HPGe) clover detectors. Each HPGe detector is shied with a BGO (Bismuth Germanate &amp;lt;nowiki&amp;gt;[&amp;lt;/nowiki&amp;gt;Bi4Ge3O12&amp;lt;nowiki&amp;gt;]&amp;lt;/nowiki&amp;gt;) shield. &lt;br /&gt;
&lt;br /&gt;
Each clover detector has 4 crystals, color-coded as Red, Blue, Green, and Black. Here is the angular map for all 16 clovers. Further details of the array can be found [https://doi.org/10.1016/j.nima.2022.167392 here] or [https://arxiv.org/abs/2208.05449 here].&lt;br /&gt;

= Introduction =&lt;br /&gt;
Clarion2 &lt;br /&gt;
&amp;lt;ref&amp;gt; T. J. Gray &#039;&#039;et. al&#039;&#039;, NIM A &#039;&#039;&#039;1041&#039;&#039;&#039;, 167392 (2022) https://doi.org/10.1016/j.nima.2022.167392&amp;lt;/ref&amp;gt;&lt;br /&gt;
is the successor of Clarion&lt;br /&gt;
&amp;lt;ref&amp;gt; C. J. Gross &#039;&#039;et. al&#039;&#039;, NIM A &#039;&#039;&#039;450&#039;&#039;&#039;, 12 (2000)  https://doi.org/10.1016/S0168-9002(00)00159-5&amp;lt;/ref&amp;gt;&lt;br /&gt;
(&#039;&#039;&#039;CL&#039;&#039;&#039;over &#039;&#039;&#039;A&#039;&#039;&#039;rray&lt;br /&gt;
for &#039;&#039;&#039;R&#039;&#039;&#039;adioactive &#039;&#039;&#039;ION&#039;&#039;&#039; beam). It is a 4π gamma ray detectors array with 16 High-Purity Germanium (HPGe) clover detectors. Each HPGe detector is shied with a BGO (Bismuth Germanate &amp;lt;nowiki&amp;gt;[&amp;lt;/nowiki&amp;gt;Bi4Ge3O12&amp;lt;nowiki&amp;gt;]&amp;lt;/nowiki&amp;gt;) shield. &lt;br /&gt;
&lt;br /&gt;
Each clover detector has 4 crystals, color-coded as Red, Blue, Green, and Black. Here is the angular map for all 16 clovers. Further details of the array can be found [https://doi.org/10.1016/j.nima.2022.167392 here] or [https://arxiv.org/abs/2208.05449 here].&lt;br /&gt;

&lt;br /&gt;
{{Notice|Solid work model needed}}&lt;br /&gt;
&lt;br /&gt;
== HPGe Clover Detector ==&lt;br /&gt;
The detectors are produced by EURISYS Measure, now CANBERRA, owned by MIRION Technologies &amp;lt;nowiki&amp;gt;[&amp;lt;/nowiki&amp;gt;[https://www.canberra.com/fr/produits/detectors/x-ray-detector-history.html 1]&amp;lt;nowiki&amp;gt;]&amp;lt;/nowiki&amp;gt;. An approximate 3.3 kg clover detector consists of 4 coaxial crystals (dimension 50 mm in diameter, 80 mm in length) &amp;lt;nowiki&amp;gt;[&amp;lt;/nowiki&amp;gt;[https://www.mirion.com/products/clover-detectors-four-coaxial-germanium-detectors Mirion webpage]&amp;lt;nowiki&amp;gt;]&amp;lt;/nowiki&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
=== Typical photon-peak efficiency curve ===&lt;br /&gt;
[[File:CLARION2 efficiency curve.png|thumb|right|400px|CLARION2 efficiency curve by Tim Gray. The data points are from experimental measurments.]]&lt;br /&gt;
&lt;br /&gt;
The absolute photo-peak efficiency at 1332 keV is ~1.8%.&lt;br /&gt;
&lt;br /&gt;
The equation for the absolute efficiency curve is&lt;br /&gt;
&lt;br /&gt;
&amp;lt;span style=&amp;quot;font-size:120%&amp;quot;&amp;gt;&lt;br /&gt;
&amp;lt;math&amp;gt; \epsilon(e_{\gamma} \text{[keV]}) = \epsilon_0 \exp^{\left( \left(A+Bx + Cx^2\right)^{-G} + \left(D+E y +F y^2\right)^{-G} \right)^{-1/G}}, &amp;lt;/math&amp;gt;&lt;br /&gt;
&amp;lt;/span&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; x = \ln\left(\frac{e_\gamma}{100}\right), y =  \ln\left(\frac{e_\gamma}{1000}\right) &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; \epsilon_0 = 0.0037679 &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; A = 13.6858 &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; B = 1.4055 &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; C = 0.000 &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; D = 3.8942 &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; E = -2.4073 &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; F = 0.0629 &amp;lt;/math&amp;gt;&lt;br /&gt;

&lt;br /&gt;
=== GEANT4 simulation ===&lt;br /&gt;
The performance of a single clover detector was simulated using GEANT4. The source code can be downloaded from https://github.com/goluckyryan/HPGeClover.&lt;br /&gt;
&lt;br /&gt;

== Trinity ==&lt;br /&gt;
[[File:Front view of TRINITY.png|400px|thumb|right|Front view of TRINITY, photo by Vandana.]]&lt;br /&gt;
Trinity is formed by GAGG (&#039;&#039;&#039;G&#039;&#039;&#039;adolinium &#039;&#039;&#039;A&#039;&#039;&#039;luminium &#039;&#039;&#039;G&#039;&#039;&#039;allium &#039;&#039;&#039;G&#039;&#039;&#039;arnet) scintillator crystals. It is located in the target chamber of the Clarion2. The GAGG crystals are arranged in 5 rings, covering 7-54 degrees. Currently only two rings are implemented, which cover 14-24 and 34-44 degrees respectively.&lt;br /&gt;
&lt;br /&gt;

&lt;br /&gt;
== Neutron Shield ==&lt;br /&gt;
&lt;br /&gt;
In 2022 April, a set of neutron shields surrounded Clarion2 for shielding slow neutrons.&lt;br /&gt;
&lt;br /&gt;
= Clarion2 private network =&lt;br /&gt;
&lt;br /&gt;
The Clarion2 uses its own private network. The network structure is illustrated as following:&lt;br /&gt;
&lt;br /&gt;
 Fox&#039;s Lab network --- clarion2(Mac, gateway) ---- 10 Gb switch&lt;br /&gt;
                                                       +--------- clarion2 DAQ&lt;br /&gt;
                                                       +--------- LN2 control, HV control&lt;br /&gt;
&lt;br /&gt;
= DAQ =&lt;br /&gt;
&lt;br /&gt;
The DAQ system is fully digitized with [[Pixie16 digitizer]]. The signals from the Clover and BGO are directly fed to the Pixie16 digitizers. The data processing library developed by Tim Gray can be found at https://github.com/belmakier/libpixie and https://github.com/belmakier/libClarionTrinity .&lt;br /&gt;
&lt;br /&gt;
The Plx driver was modified from the Broadcom driver. The PixieSDK (legacy) was also modified. &lt;br /&gt;
&lt;br /&gt;
{{Notice | Detail of operation is needed.}}&lt;br /&gt;
&lt;br /&gt;
= LN2 cooling system =&lt;br /&gt;
The liquid Nitrogen (LN2) filling system developed by Mitch Allmond (Oak Ridge) is hosted on the LN2-control computer under the account &amp;quot;ln@ln02&amp;quot;.&lt;br /&gt;
=== Changing Alert List ===&lt;br /&gt;
To change the alert list, edit ~/scripts/run-send-alarms.sh with the relevant emails.&lt;br /&gt;
== ln@ln02 Directory==&lt;br /&gt;
Several important directories for using the LN2 system are listed below. &lt;br /&gt;
=== /gln ===&lt;br /&gt;
/gln is the most important directory, it is where the control program is located and for most problems is where you will need to go&lt;br /&gt;

= Introduction =&lt;br /&gt;
Clarion2 &lt;br /&gt;
&amp;lt;ref&amp;gt; T. J. Gray &#039;&#039;et. al&#039;&#039;, NIM A &#039;&#039;&#039;1041&#039;&#039;&#039;, 167392 (2022) https://doi.org/10.1016/j.nima.2022.167392&amp;lt;/ref&amp;gt;&lt;br /&gt;
is the successor of Clarion&lt;br /&gt;
&amp;lt;ref&amp;gt; C. J. Gross &#039;&#039;et. al&#039;&#039;, NIM A &#039;&#039;&#039;450&#039;&#039;&#039;, 12 (2000)  https://doi.org/10.1016/S0168-9002(00)00159-5&amp;lt;/ref&amp;gt;&lt;br /&gt;
(&#039;&#039;&#039;CL&#039;&#039;&#039;over &#039;&#039;&#039;A&#039;&#039;&#039;rray&lt;br /&gt;
for &#039;&#039;&#039;R&#039;&#039;&#039;adioactive &#039;&#039;&#039;ION&#039;&#039;&#039; beam). It is a 4π gamma ray detectors array with 16 High-Purity Germanium (HPGe) clover detectors. Each HPGe detector is shied with a BGO (Bismuth Germanate &amp;lt;nowiki&amp;gt;[&amp;lt;/nowiki&amp;gt;Bi4Ge3O12&amp;lt;nowiki&amp;gt;]&amp;lt;/nowiki&amp;gt;) shield. &lt;br /&gt;
&lt;br /&gt;
Each clover detector has 4 crystals, color-coded as Red, Blue, Green, and Black. Here is the angular map for all 16 clovers. Further details of the array can be found [https://doi.org/10.1016/j.nima.2022.167392 here] or [https://arxiv.org/abs/2208.05449 here].&lt;br /&gt;
&lt;br /&gt;
[[File:Clarion2 angular map.png|400px|thumb|none|Clarion2 angular map. The purple dot is the center of each clover.]]&lt;br /&gt;
&lt;br /&gt;
{{Notice|Solid work model needed}}&lt;br /&gt;
&lt;br /&gt;
== HPGe Clover Detector ==&lt;br /&gt;
The detectors are produced by EURISYS Measure, now CANBERRA, owned by MIRION Technologies &amp;lt;nowiki&amp;gt;[&amp;lt;/nowiki&amp;gt;[https://www.canberra.com/fr/produits/detectors/x-ray-detector-history.html 1]&amp;lt;nowiki&amp;gt;]&amp;lt;/nowiki&amp;gt;. An approximate 3.3 kg clover detector consists of 4 coaxial crystals (dimension 50 mm in diameter, 80 mm in length) &amp;lt;nowiki&amp;gt;[&amp;lt;/nowiki&amp;gt;[https://www.mirion.com/products/clover-detectors-four-coaxial-germanium-detectors Mirion webpage]&amp;lt;nowiki&amp;gt;]&amp;lt;/nowiki&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
=== Typical photon-peak efficiency curve ===&lt;br /&gt;
[[File:CLARION2 efficiency curve.png|thumb|right|400px|CLARION2 efficiency curve by Tim Gray. The data points are from experimental measurments.]]&lt;br /&gt;
&lt;br /&gt;
The absolute photo-peak efficiency at 1332 keV is ~1.8%.&lt;br /&gt;
&lt;br /&gt;
The equation for the absolute efficiency curve is&lt;br /&gt;
&lt;br /&gt;
&amp;lt;span style=&amp;quot;font-size:120%&amp;quot;&amp;gt;&lt;br /&gt;
&amp;lt;math&amp;gt; \epsilon(e_{\gamma} \text{[keV]}) = \epsilon_0 \exp^{\left( \left(A+Bx + Cx^2\right)^{-G} + \left(D+E y +F y^2\right)^{-G} \right)^{-1/G}}, &amp;lt;/math&amp;gt;&lt;br /&gt;
&amp;lt;/span&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; x = \ln\left(\frac{e_\gamma}{100}\right), y =  \ln\left(\frac{e_\gamma}{1000}\right) &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; \epsilon_0 = 0.0037679 &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; A = 13.6858 &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; B = 1.4055 &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; C = 0.000 &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; D = 3.8942 &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; E = -2.4073 &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; F = 0.0629 &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; G = 0.5000 &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
=== GEANT4 simulation ===&lt;br /&gt;
The performance of a single clover detector was simulated using GEANT4. The source code can be downloaded from https://github.com/goluckyryan/HPGeClover.&lt;br /&gt;
&lt;br /&gt;
[[File:GEAN4 simulation of 152Eu.png|600px|thumb|none|GEANT4 simulation of 152Eu]]&lt;br /&gt;
&lt;br /&gt;
A GEANT4 simulation for Clarion2 can be found at https://fsunuc.physics.fsu.edu/git/pderosa888/CLARION2_GEANT4.&lt;br /&gt;
&lt;br /&gt;

&lt;br /&gt;
== Trinity ==&lt;br /&gt;
[[File:Front view of TRINITY.png|400px|thumb|right|Front view of TRINITY, photo by Vandana.]]&lt;br /&gt;
Trinity is formed by GAGG (&#039;&#039;&#039;G&#039;&#039;&#039;adolinium &#039;&#039;&#039;A&#039;&#039;&#039;luminium &#039;&#039;&#039;G&#039;&#039;&#039;allium &#039;&#039;&#039;G&#039;&#039;&#039;arnet) scintillator crystals. It is located in the target chamber of the Clarion2. The GAGG crystals are arranged in 5 rings, covering 7-54 degrees. Currently only two rings are implemented, which cover 14-24 and 34-44 degrees respectively.&lt;br /&gt;
&lt;br /&gt;

&lt;br /&gt;
== Neutron Shield ==&lt;br /&gt;
&lt;br /&gt;
In 2022 April, a set of neutron shields surrounded Clarion2 for shielding slow neutrons.&lt;br /&gt;
&lt;br /&gt;
= Clarion2 private network =&lt;br /&gt;
&lt;br /&gt;
The Clarion2 uses its own private network. The network structure is illustrated as following:&lt;br /&gt;
&lt;br /&gt;
 Fox&#039;s Lab network --- clarion2(Mac, gateway) ---- 10 Gb switch&lt;br /&gt;
                                                       +--------- clarion2 DAQ&lt;br /&gt;
                                                       +--------- LN2 control, HV control&lt;br /&gt;
&lt;br /&gt;
= DAQ =&lt;br /&gt;
&lt;br /&gt;
The DAQ system is fully digitized with [[Pixie16 digitizer]]. The signals from the Clover and BGO are directly fed to the Pixie16 digitizers. The data processing library developed by Tim Gray can be found at https://github.com/belmakier/libpixie and https://github.com/belmakier/libClarionTrinity .&lt;br /&gt;
&lt;br /&gt;
The Plx driver was modified from the Broadcom driver. The PixieSDK (legacy) was also modified. &lt;br /&gt;
&lt;br /&gt;
{{Notice | Detail of operation is needed.}}&lt;br /&gt;
&lt;br /&gt;
= LN2 cooling system =&lt;br /&gt;
The liquid Nitrogen (LN2) filling system developed by Mitch Allmond (Oak Ridge) is hosted on the LN2-control computer under the account &amp;quot;ln@ln02&amp;quot;.&lt;br /&gt;
=== Changing Alert List ===&lt;br /&gt;
To change the alert list, edit ~/scripts/run-send-alarms.sh with the relevant emails.&lt;br /&gt;
== ln@ln02 Directory==&lt;br /&gt;
Several important directories for using the LN2 system are listed below. &lt;br /&gt;
=== /gln ===&lt;br /&gt;
/gln is the most important directory, it is where the control program is located and for most problems is where you will need to go&lt;br /&gt;
==== gln_ui ====&lt;br /&gt;
gln_ui is the user interface to issue commands to the fill program&lt;br /&gt;
&amp;lt;div class=&amp;quot;toccolours mw-collapsible mw-collapsed&amp;quot;&amp;gt;&lt;br /&gt;
&amp;lt;div style=&amp;quot;line-height:1.6;&amp;quot;&amp;gt;gln_ui Commands&amp;lt;/div&amp;gt;&lt;br /&gt;
