('''CL'''over '''A'''rray<br />
for '''R'''adioactive '''ION''' 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 <nowiki>[</nowiki>Bi4Ge3O12<nowiki>]</nowiki>) shield. <br />
<br />
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].<br />

== Trinity ==<br />
[[File:Front view of TRINITY.png|400px|thumb|right|Front view of TRINITY, photo by Vandana.]]<br />
Trinity is formed by GAGG ('''G'''adolinium '''A'''luminium '''G'''allium '''G'''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.<br />

== Neutron Shield ==<br />
<br />
In 2022 April, a set of neutron shields surrounded Clarion2 for shielding slow neutrons.<br />
<br />
= Clarion2 private network =<br />
<br />
The Clarion2 uses its own private network. The network structure is illustrated as following:<br />
<br />
Fox's Lab network --- clarion2(Mac, gateway) ---- 10 Gb switch<br />
+--------- clarion2 DAQ<br />
+--------- LN2 control, HV control<br />
<br />
== MacOS Updates ==<br />
Recently IT asked us to do an update of the Mac Mini / gateway PC. The update generally went fine, just use the built in software updater. As of now of it is running MacOS Sequoia 15.75. You must confirm that the network settings are the same between the updates. <br />
<br />
The major issue was the apache web service / web server was not working with the new update. Truly, Mitch fixed this, these suggestions are regurgitation of what he did.<br />
<br />
# Some new permission modules in httpd.conf had to be uncommented<br />
# A new file in /etc/apache/extras/ was added and a line for users sites had to be uncommented<br />
# "all granted" had to be added to clarion02.conf<br />
# had to run chmod +x "_www allow execute" ~<br />
<br />
These are likely not the same issues that will be faced the next time the OS is updated but give you hints at the kinds of things to look for. Best of luck!<br />
<br />
= DAQ =<br />
<br />
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 .<br />
<br />
The Plx driver was modified from the Broadcom driver. The PixieSDK (legacy) was also modified. <br />
<br />
{{Notice | Detail of operation is needed.}}<br />
<br />
==Casual Tutorial For Getting a Pixie Crate Up and Running==<br />
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.<br />
===Prerequisites===<br />
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.<br />
<br />
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.<br />
<br />
Make sure you are running Ubuntu 18 with kernel 4.15. The drivers will work with this setup only.<br />
<br />
===Installation===<br />
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. Make sure that the crate is one and plugged into the optical PCI card on the PC prior to booting the PC.<br />
<br />
Navigate to <code> cd ~/pxi/PlxSdk/ </code><br />
Once here give the commands:<br />
<br />
<code> make clean </code><br />
<code> make </code><br />
<br />
This will build a bunch of stuff.<br />
Next, navigate to the Drivers folder: <code> cd ~/pxi/PlxSdk/Drivers </code><br />
<br />
I had the most luck with the "builddrivers.sh" script.<br />
<br />
Start with the PCI drivers: <code> ./builddrivers Svc </code><br />
<br />
This will likely throw some errors. If it does find the Dispatch.c script is it complaining about, probably here: ~/pxi/PlxSdk/Driver/PlxSvc/<br />
<br />
Next build the 9054 drivers with <code> ./builddrivers 9054 </code><br />
<br />
This is the step that I struggled with the most. It is possible that the PXI optical PCI card will not be recognized as such. Make sure that nothing else has the same "address" I had to blacklist some network driver trying to claim the optical card.<br />
<br />
Finally, navigate to <code> /home/clarion/pxi/Pixie16/lib </code> and use the make command. This step always went smoothly for me.<br />
<br />
This should get the system ready to run the DAQ software. You can check with Pixie16Load, Pixie16Boot, or Pixie16Set. If everything is working, when you run the boot command, the frequency of the hum from the crate will change.<br />
<br />
===Troubleshooting===<br />
<br />
The first thing to check is that the PXI optical comm card and the PC's PCI optical board are compatible. They need to be the same model number or very close. Below is an inventory of compatible boards and where they are now.<br />
<br />
If you are running Pixie16Boot and getting errors or nothing, try running Pixie16Load first.<br />
<br />
= LeCroy HV Mainframe=<br />
The clovers and BGOs bias is supplied by two LeCroy 1458 HV Mainframes. These are controlled via a serial connection to the LN02 PC.<br />
<br />
===Clearing Panic Status===<br />
<br />
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 "PANIC OFF" button will be on.<br />
To clear the Panic status:<br />
#Turn key to "Local"<br />
#Press the "HV Off" button. This should clear the status and make the red panic lights go out.<br />
#TURN THE KEY BACK TO REMOTE!!! This is important so we can control the system via the serial connection.<br />
<br />
You will need to do this procedure for each mainframe.<br />
<br />
= LN2 cooling system =<br />
The liquid Nitrogen (LN2) filling system developed by Mitch Allmond (Oak Ridge) is hosted on the LN2-control computer under the account "ln@ln02".<br />
=== Changing Alert List ===<br />
To change the alert list, edit ~/scripts/run-send-alarms.sh with the relevant emails.<br />
== ln@ln02 Directory==<br />
Several important directories for using the LN2 system are listed below. <br />
=== /gln ===<br />
/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<br />
==== gln_ui ====<br />
gln_ui is the user interface to issue commands to the fill program<br />

The first thing to check is that the PXI optical comm card and the PC's PCI optical board are compatible. They need to be the same model number or very close. Below is an inventory of compatible boards and where they are now.<br />
<br />
If you are running Pixie16Boot and getting errors or nothing, try running Pixie16Load first.<br />
<br />
= LeCroy HV Mainframe=<br />
The clovers and BGOs bias is supplied by two LeCroy 1458 HV Mainframes. These are controlled via a serial connection to the LN02 PC.<br />
<br />
===Clearing Panic Status===<br />
<br />
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 "PANIC OFF" button will be on.<br />
To clear the Panic status:<br />
#Turn key to "Local"<br />
#Press the "HV Off" button. This should clear the status and make the red panic lights go out.<br />
#TURN THE KEY BACK TO REMOTE!!! This is important so we can control the system via the serial connection.<br />
<br />
You will need to do this procedure for each mainframe.<br />
<br />
= LN2 cooling system =<br />
The liquid Nitrogen (LN2) filling system developed by Mitch Allmond (Oak Ridge) is hosted on the LN2-control computer under the account "ln@ln02".<br />
=== Changing Alert List ===<br />
To change the alert list, edit ~/scripts/run-send-alarms.sh with the relevant emails.<br />
== ln@ln02 Directory==<br />
Several important directories for using the LN2 system are listed below. <br />
=== /gln ===<br />
/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<br />
==== gln_ui ====<br />
gln_ui is the user interface to issue commands to the fill program<br />

('''CL'''over '''A'''rray<br />
for '''R'''adioactive '''ION''' 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 <nowiki>[</nowiki>Bi4Ge3O12<nowiki>]</nowiki>) shield. <br />
<br />
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].<br />

Trinity is formed by GAGG ('''G'''adolinium '''A'''luminium '''G'''allium '''G'''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.<br />

== Neutron Shield ==<br />
<br />
In 2022 April, a set of neutron shields surrounded Clarion2 for shielding slow neutrons.<br />
<br />
= Clarion2 private network =<br />
<br />
The Clarion2 uses its own private network. The network structure is illustrated as following:<br />
<br />
Fox's Lab network --- clarion2(Mac, gateway) ---- 10 Gb switch<br />
+--------- clarion2 DAQ<br />
+--------- LN2 control, HV control<br />
<br />
== MacOS Updates ==<br />
Recently IT asked us to do an update of the Mac Mini / gateway PC. The update generally went fine, just use the built in software updater. As of now of it is running MacOS Sequoia 15.75. You must confirm that the network settings are the same between the updates. <br />
<br />
The major issue was the apache web service / web server was not working with the new update. Truly, Mitch fixed this, these suggestions are regurgitation of what he did.<br />
<br />
# Some new permission modules in httpd.conf had to be uncommented<br />
# A new file in /etc/apache/extras/ was added and a line for users sites had to be uncommented<br />
# "all granted" had to be added to clarion02.conf<br />
# had to run chmod +x "_www allow execute" ~<br />
<br />
These are likely not the same issues that will be faced the next time the OS is updated but give you hints at the kinds of things to look for. Best of luck!<br />
<br />
= DAQ =<br />
<br />
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 .<br />
<br />
The Plx driver was modified from the Broadcom driver. The PixieSDK (legacy) was also modified. <br />
<br />
{{Notice | Detail of operation is needed.}}<br />
<br />
==Casual Tutorial For Getting a Pixie Crate Up and Running==<br />
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.<br />
===Prerequisites===<br />
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.<br />
<br />
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.<br />
<br />
Make sure you are running Ubuntu 18 with kernel 4.15. The drivers will work with this setup only.<br />
<br />
===Installation===<br />
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. Make sure that the crate is one and plugged into the optical PCI card on the PC prior to booting the PC.<br />
<br />
Navigate to <code> cd ~/pxi/PlxSdk/ </code><br />
Once here give the commands:<br />
<br />
<code> make clean </code><br />
<code> make </code><br />
<br />
This will build a bunch of stuff.<br />
Next, navigate to the Drivers folder: <code> cd ~/pxi/PlxSdk/Drivers </code><br />
<br />
I had the most luck with the "builddrivers.sh" script.<br />
<br />
Start with the PCI drivers: <code> ./builddrivers Svc </code><br />
<br />
This will likely throw some errors. If it does find the Dispatch.c script is it complaining about, probably here: ~/pxi/PlxSdk/Driver/PlxSvc/<br />
<br />
Next build the 9054 drivers with <code> ./builddrivers 9054 </code><br />
<br />
This is the step that I struggled with the most. It is possible that the PXI optical PCI card will not be recognized as such. Make sure that nothing else has the same "address" I had to blacklist some network driver trying to claim the optical card.<br />
<br />
Finally, navigate to <code> /home/clarion/pxi/Pixie16/lib </code> and use the make command. This step always went smoothly for me.<br />
<br />
This should get the system ready to run the DAQ software. You can check with Pixie16Load, Pixie16Boot, or Pixie16Set. If everything is working, when you run the boot command, the frequency of the hum from the crate will change.<br />
<br />
= LeCroy HV Mainframe=<br />
The clovers and BGOs bias is supplied by two LeCroy 1458 HV Mainframes. These are controlled via a serial connection to the LN02 PC.<br />
<br />
===Clearing Panic Status===<br />
<br />
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 "PANIC OFF" button will be on.<br />
To clear the Panic status:<br />
#Turn key to "Local"<br />
#Press the "HV Off" button. This should clear the status and make the red panic lights go out.<br />
#TURN THE KEY BACK TO REMOTE!!! This is important so we can control the system via the serial connection.<br />
<br />
You will need to do this procedure for each mainframe.<br />

The performance of a single clover detector was simulated using GEANT4. The source code can be downloaded from https://github.com/goluckyryan/HPGeClover.<br />
<br />

<br />
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<br />

== Trinity ==<br />
[[File:Front view of TRINITY.png|400px|thumb|right|Front view of TRINITY, photo by Vandana.]]<br />
Trinity is formed by GAGG ('''G'''adolinium '''A'''luminium '''G'''allium '''G'''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.<br />
<br />

== Neutron Shield ==<br />
<br />
In 2022 April, a set of neutron shields surrounded Clarion2 for shielding slow neutrons.<br />
<br />
= Clarion2 private network =<br />
<br />
The Clarion2 uses its own private network. The network structure is illustrated as following:<br />
<br />
Fox's Lab network --- clarion2(Mac, gateway) ---- 10 Gb switch<br />
+--------- clarion2 DAQ<br />
+--------- LN2 control, HV control<br />
<br />
== MacOS Updates ==<br />
Recently IT asked us to do an update of the Mac Mini / gateway PC. The update generally went fine, just use the built in software updater. As of now of it is running MacOS Sequoia 15.75. You must confirm that the network settings are the same between the updates. <br />
<br />
The major issue was the apache web service / web server was not working with the new update. Truly, Mitch fixed this, these suggestions are regurgitation of what he did.<br />
<br />
# Some new permission modules in httpd.conf had to be uncommented<br />
# A new file in /etc/apache/extras/ was added and a line for users sites had to be uncommented<br />
# "all granted" had to be added to clarion02.conf<br />
# had to run chmod +x "_www allow execute" ~<br />
<br />
These are likely not the same issues that will be faced the next time the OS is updated but give you hints at the kinds of things to look for. Best of luck!<br />
<br />
= DAQ =<br />
<br />
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 .<br />
<br />
The Plx driver was modified from the Broadcom driver. The PixieSDK (legacy) was also modified. <br />
<br />
{{Notice | Detail of operation is needed.}}<br />
<br />
==Casual Tutorial For Getting a Pixie Crate Up and Running==<br />
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.<br />
===Prerequisites===<br />
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.<br />
<br />
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.<br />
<br />
Make sure you are running Ubuntu 18 with kernel 4.15. The drivers will work with this setup only.<br />
<br />
===Installation===<br />
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.<br />
<br />
Navigate to <code> cd ~/pxi/PlxSdk/ </code><br />
Once here give the commands:<br />
<br />
<code> make clean </code><br />
<code> make </code><br />
<br />
This will build a bunch of stuff.<br />
Next, navigate to the Drivers folder: <code> cd ~/pxi/PlxSdk/Drivers </code><br />
<br />
I had the most luck with the "builddrivers.sh" script.<br />
<br />
Start with the PCI drivers: <code> ./builddrivers Svc </code><br />
<br />
This will likely throw some errors. If it does find the Dispatch.c script is it complaining about, probably here: ~/pxi/PlxSdk/Driver/PlxSvc/<br />
<br />
Edit the includes to look like this:<br />
<br />
... I need to find the script so that I can copy the header.... Bad me<br />
<br />
<br />
<br />
<br />
= LeCroy HV Mainframe=<br />
The clovers and BGOs bias is supplied by two LeCroy 1458 HV Mainframes. These are controlled via a serial connection to the LN02 PC.<br />
<br />
===Clearing Panic Status===<br />
<br />
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 "PANIC OFF" button will be on.<br />
To clear the Panic status:<br />
#Turn key to "Local"<br />
#Press the "HV Off" button. This should clear the status and make the red panic lights go out.<br />
#TURN THE KEY BACK TO REMOTE!!! This is important so we can control the system via the serial connection.<br />
<br />
You will need to do this procedure for each mainframe.<br />
<br />
= LN2 cooling system =<br />
The liquid Nitrogen (LN2) filling system developed by Mitch Allmond (Oak Ridge) is hosted on the LN2-control computer under the account "ln@ln02".<br />
=== Changing Alert List ===<br />
To change the alert list, edit ~/scripts/run-send-alarms.sh with the relevant emails.<br />
== ln@ln02 Directory==<br />
Several important directories for using the LN2 system are listed below. <br />
=== /gln ===<br />
/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<br />
==== gln_ui ====<br />
gln_ui is the user interface to issue commands to the fill program<br />

('''CL'''over '''A'''rray<br />
for '''R'''adioactive '''ION''' 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 <nowiki>[</nowiki>Bi4Ge3O12<nowiki>]</nowiki>) shield. <br />
<br />
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].<br />

Trinity is formed by GAGG ('''G'''adolinium '''A'''luminium '''G'''allium '''G'''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.<br />

== Neutron Shield ==<br />
<br />
In 2022 April, a set of neutron shields surrounded Clarion2 for shielding slow neutrons.<br />
<br />
= Clarion2 private network =<br />
<br />
The Clarion2 uses its own private network. The network structure is illustrated as following:<br />
<br />
Fox's Lab network --- clarion2(Mac, gateway) ---- 10 Gb switch<br />
+--------- clarion2 DAQ<br />
+--------- LN2 control, HV control<br />
<br />
= DAQ =<br />
<br />
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 .<br />
<br />
The Plx driver was modified from the Broadcom driver. The PixieSDK (legacy) was also modified. <br />
<br />
{{Notice | Detail of operation is needed.}}<br />
<br />
==Casual Tutorial For Getting a Pixie Crate Up and Running==<br />
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.<br />
===Prerequisites===<br />
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.<br />
<br />
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.<br />
<br />
Make sure you are running Ubuntu 18 with kernel 4.15. The drivers will work with this setup only.<br />
<br />
===Installation===<br />
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.<br />
<br />
Navigate to <code> cd ~/pxi/PlxSdk/ </code><br />
Once here give the commands:<br />
<br />
<code> make clean </code><br />
<code> make </code><br />
<br />
This will build a bunch of stuff.<br />
Next, navigate to the Drivers folder: <code> cd ~/pxi/PlxSdk/Drivers </code><br />
<br />
I had the most luck with the "builddrivers.sh" script.<br />
<br />
Start with the PCI drivers: <code> ./builddrivers Svc </code><br />
<br />
This will likely throw some errors. If it does find the Dispatch.c script is it complaining about, probably here: ~/pxi/PlxSdk/Driver/PlxSvc/<br />
<br />
Edit the includes to look like this:<br />
<br />
... I need to find the script so that I can copy the header.... Bad me<br />
<br />
<br />
<br />
<br />
= LeCroy HV Mainframe=<br />
The clovers and BGOs bias is supplied by two LeCroy 1458 HV Mainframes. These are controlled via a serial connection to the LN02 PC.<br />
<br />
===Clearing Panic Status===<br />
<br />
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 "PANIC OFF" button will be on.<br />
To clear the Panic status:<br />
#Turn key to "Local"<br />
#Press the "HV Off" button. This should clear the status and make the red panic lights go out.<br />
#TURN THE KEY BACK TO REMOTE!!! This is important so we can control the system via the serial connection.<br />
<br />
You will need to do this procedure for each mainframe.<br />
<br />
= LN2 cooling system =<br />
The liquid Nitrogen (LN2) filling system developed by Mitch Allmond (Oak Ridge) is hosted on the LN2-control computer under the account "ln@ln02".<br />
=== Changing Alert List ===<br />
To change the alert list, edit ~/scripts/run-send-alarms.sh with the relevant emails.<br />
== ln@ln02 Directory==<br />
Several important directories for using the LN2 system are listed below. <br />
=== /gln ===<br />
/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<br />
==== gln_ui ====<br />
gln_ui is the user interface to issue commands to the fill program<br />

('''CL'''over '''A'''rray<br />
for '''R'''adioactive '''ION''' 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 <nowiki>[</nowiki>Bi4Ge3O12<nowiki>]</nowiki>) shield. <br />
<br />
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].<br />

=== Typical photon-peak efficiency curve ===<br />
[[File:CLARION2 efficiency curve.png|thumb|right|400px|CLARION2 efficiency curve by Tim Gray. The data points are from experimental measurments.]]<br />
<br />
The absolute photo-peak efficiency at 1332 keV is ~1.8%.<br />
<br />
The equation for the absolute efficiency curve is<br />
<br />
<span style="font-size:120%"><br />
<math> \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}}, </math><br />

=== GEANT4 simulation ===<br />
The performance of a single clover detector was simulated using GEANT4. The source code can be downloaded from https://github.com/goluckyryan/HPGeClover.<br />
<br />
[[File:GEAN4 simulation of 152Eu.png|600px|thumb|none|GEANT4 simulation of 152Eu]]<br />
<br />
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<br />

== Trinity ==<br />
[[File:Front view of TRINITY.png|400px|thumb|right|Front view of TRINITY, photo by Vandana.]]<br />
Trinity is formed by GAGG ('''G'''adolinium '''A'''luminium '''G'''allium '''G'''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.<br />
<br />
[[File:A single GAGG detector.png|400px|thumb|none|A single GAGG detector]]<br />
<br />
== Neutron Shield ==<br />
<br />
In 2022 April, a set of neutron shields surrounded Clarion2 for shielding slow neutrons.<br />
<br />
= Clarion2 private network =<br />
<br />
The Clarion2 uses its own private network. The network structure is illustrated as following:<br />
<br />
Fox's Lab network --- clarion2(Mac, gateway) ---- 10 Gb switch<br />
+--------- clarion2 DAQ<br />
+--------- LN2 control, HV control<br />
<br />
= DAQ =<br />
<br />
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 .<br />
<br />
The Plx driver was modified from the Broadcom driver. The PixieSDK (legacy) was also modified. <br />
<br />
{{Notice | Detail of operation is needed.}}<br />
<br />
= LeCroy HV Mainframe=<br />
The clovers and BGOs bias is supplied by two LeCroy 1458 HV Mainframes. These are controlled via a serial connection to the LN02 PC.<br />
<br />
===Clearing Panic Status===<br />
<br />
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 "PANIC OFF" button will be on.<br />
To clear the Panic status:<br />
#Turn key to "Local"<br />
#Press the "HV Off" button. This should clear the status and make the red panic lights go out.<br />
#TURN THE KEY BACK TO REMOTE!!! This is important so we can control the system via the serial connection.<br />
<br />
You will need to do this procedure for each mainframe.<br />
<br />
= LN2 cooling system =<br />
The liquid Nitrogen (LN2) filling system developed by Mitch Allmond (Oak Ridge) is hosted on the LN2-control computer under the account "ln@ln02".<br />
=== Changing Alert List ===<br />
To change the alert list, edit ~/scripts/run-send-alarms.sh with the relevant emails.<br />
== ln@ln02 Directory==<br />
Several important directories for using the LN2 system are listed below. <br />
=== /gln ===<br />
/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<br />
==== gln_ui ====<br />
gln_ui is the user interface to issue commands to the fill program<br />

('''CL'''over '''A'''rray<br />
for '''R'''adioactive '''ION''' 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 <nowiki>[</nowiki>Bi4Ge3O12<nowiki>]</nowiki>) shield. <br />
<br />
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].<br />

The detectors are produced by EURISYS Measure, now CANBERRA, owned by MIRION Technologies <nowiki>[</nowiki>[https://www.canberra.com/fr/produits/detectors/x-ray-detector-history.html 1]<nowiki>]</nowiki>. An approximate 3.3 kg clover detector consists of 4 coaxial crystals (dimension 50 mm in diameter, 80 mm in length) <nowiki>[</nowiki>[https://www.mirion.com/products/clover-detectors-four-coaxial-germanium-detectors Mirion webpage]<nowiki>]</nowiki>.<br />

=== Typical photon-peak efficiency curve ===<br />
[[File:CLARION2 efficiency curve.png|thumb|right|400px|CLARION2 efficiency curve by Tim Gray. The data points are from experimental measurments.]]<br />
<br />
The absolute photo-peak efficiency at 1332 keV is ~1.8%.<br />
<br />
The equation for the absolute efficiency curve is<br />
<br />
<span style="font-size:120%"><br />
<math> \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}}, </math><br />
</span><br />
<br />
<math> x = \ln\left(\frac{e_\gamma}{100}\right), y = \ln\left(\frac{e_\gamma}{1000}\right) </math><br />

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

<br />
== Trinity ==<br />
[[File:Front view of TRINITY.png|400px|thumb|right|Front view of TRINITY, photo by Vandana.]]<br />
Trinity is formed by GAGG ('''G'''adolinium '''A'''luminium '''G'''allium '''G'''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.<br />
<br />
[[File:A single GAGG detector.png|400px|thumb|none|A single GAGG detector]]<br />
<br />
== Neutron Shield ==<br />
<br />
In 2022 April, a set of neutron shields surrounded Clarion2 for shielding slow neutrons.<br />
<br />
= Clarion2 private network =<br />
<br />
The Clarion2 uses its own private network. The network structure is illustrated as following:<br />
<br />
Fox's Lab network --- clarion2(Mac, gateway) ---- 10 Gb switch<br />
+--------- clarion2 DAQ<br />
+--------- LN2 control, HV control<br />
<br />
= DAQ =<br />
<br />
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 .<br />
<br />
The Plx driver was modified from the Broadcom driver. The PixieSDK (legacy) was also modified. <br />
<br />
{{Notice | Detail of operation is needed.}}<br />
<br />
= LeCroy HV Mainframe=<br />
The clovers and BGOs bias is supplied by two LeCroy 1458 HV Mainframes. These are controlled via a serial connection to the LN02 PC.<br />
<br />
===Clearing Panic Status===<br />
<br />
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 "PANIC OFF" button will be on.<br />
To clear the Panic status:<br />
#Turn key to "Local"<br />
#Press the "HV Off" button. This should clear the status and make the red panic lights go out.<br />
#TURN THE KEY BACK TO REMOTE!!! This is important so we can control the system via the serial connection.<br />
<br />
You will need to do this procedure for each mainframe.<br />
<br />
= LN2 cooling system =<br />
The liquid Nitrogen (LN2) filling system developed by Mitch Allmond (Oak Ridge) is hosted on the LN2-control computer under the account "ln@ln02".<br />
=== Changing Alert List ===<br />
To change the alert list, edit ~/scripts/run-send-alarms.sh with the relevant emails.<br />
== ln@ln02 Directory==<br />
Several important directories for using the LN2 system are listed below. <br />
=== /gln ===<br />
/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<br />
==== gln_ui ====<br />
gln_ui is the user interface to issue commands to the fill program<br />

<br />
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].<br />

== Trinity ==<br />
[[File:Front view of TRINITY.png|400px|thumb|right|Front view of TRINITY, photo by Vandana.]]<br />
Trinity is formed by GAGG ('''G'''adolinium '''A'''luminium '''G'''allium '''G'''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.<br />
<br />

<br />
== Neutron Shield ==<br />
<br />
In 2022 April, a set of neutron shields surrounded Clarion2 for shielding slow neutrons.<br />
<br />
= Clarion2 private network =<br />
<br />
The Clarion2 uses its own private network. The network structure is illustrated as following:<br />
<br />
Fox's Lab network --- clarion2(Mac, gateway) ---- 10 Gb switch<br />
+--------- clarion2 DAQ<br />
+--------- LN2 control, HV control<br />
<br />
= DAQ =<br />
<br />
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 .<br />
<br />
The Plx driver was modified from the Broadcom driver. The PixieSDK (legacy) was also modified. <br />
<br />
{{Notice | Detail of operation is needed.}}<br />
<br />
= LN2 cooling system =<br />
The liquid Nitrogen (LN2) filling system developed by Mitch Allmond (Oak Ridge) is hosted on the LN2-control computer under the account "ln@ln02".<br />
=== Changing Alert List ===<br />
To change the alert list, edit ~/scripts/run-send-alarms.sh with the relevant emails.<br />
== ln@ln02 Directory==<br />
Several important directories for using the LN2 system are listed below. <br />
=== /gln ===<br />
/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<br />

== Trinity ==<br />
[[File:Front view of TRINITY.png|400px|thumb|right|Front view of TRINITY, photo by Vandana.]]<br />
Trinity is formed by GAGG ('''G'''adolinium '''A'''luminium '''G'''allium '''G'''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.<br />

<br />
== Neutron Shield ==<br />
<br />
In 2022 April, a set of neutron shields surrounded Clarion2 for shielding slow neutrons.<br />
<br />
= Clarion2 private network =<br />
<br />
The Clarion2 uses its own private network. The network structure is illustrated as following:<br />
<br />
Fox's Lab network --- clarion2(Mac, gateway) ---- 10 Gb switch<br />
+--------- clarion2 DAQ<br />
+--------- LN2 control, HV control<br />
<br />
= DAQ =<br />
<br />
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 .<br />
<br />
The Plx driver was modified from the Broadcom driver. The PixieSDK (legacy) was also modified. <br />
<br />
{{Notice | Detail of operation is needed.}}<br />
