Clarion2
Introduction
Clarion2 is the successor of Clarion. It is a 4π gamma ray detectors array.
HPGe Clover Detector
Trinity
Trinity is GAGG (stand for ?) detector array.
DAQ
LN2 cooling system
The liquid Nitrogen (LN2) filling system developed by Mitch Allmond (Oak Ridge) is hosted on the DAQ computer under account "ln@ln02".
ln@ln02 Directory
Several important directories for using the LN2 system are listed below.
/gln
/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
gln_ui
gln_ui is the user interface to issue commands to the fill program
fill <det-list>- fill detectors <det-list> now
fill <det-list> after <number-of-minutes>(or <hours:- minutes>)
- wait to fill detectors <det-list> by time <hours:minutes>
cool <det-list>- cool down detectors
ton <det-list>- turn on (enable fill for) detectors
tof <det-list>- turn off (disable fill for) detectors
con det#[.temp#]- turn on checking of detector temps
cof det#[.temp#]- turn off checking of detector temps
abort- abort and disable all fills
load [fig-file-name] - load configuration from fig-file-name (default = gln.fig) exit-master - exit gln_master process clr - clear all errors for entire system clrd <det-list> - clear errors for specific detectors clrs - clear all slot errors clrm - clear all manifold errors
d - display status dt - display times of all detectors & manifolds (formatted dates and times) dts - display times of all detectors & manifolds (in seconds) dc - display configuration (valve and ADC IDs, etc) mon - enter monitor mode; type control-C to exit quit - exit gln_ui process hvln - useless command for backward compatibility clear - clear screen ? or help - this output
extra low-level debugging commands:
radc <#> - read ADC number <#> opv <#>, clv <#> - open and close valves (TAKE CARE!)
