Clarion2

Introduction

Clarion2 is the successor of Clarion. It is a 4π gamma ray detectors array.

Trinity

Trinity is GAGG (stand for ?) detector array.

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

gln_ui Commands

---

fill <det-list> - fill detectors now fill <det-list> after <number-of-minutes> (or <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

                       <det-list> example:  1 4 5

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!)
