Login on LN computer
The LN computer lives in the GRETINA net and doesn't know about the outside world.
- login on gateway machine nsclgw1.nscl.msu.edu
- login as gretina on a2.gam (35.8.35.163)
- login as ln on gln1 (10.0.4.11)
- Rememeber: “liquid nitrogen two for gretina”
LN scripts
They are found in ~/scripts. The main LN program (gln_master) is a job run by root and not directly accessible by the user. Interactions happen via scripts. Most interesting is run-gln-ui.sh, the User Interface.
- run-gln-ui.sh: User Interface, 'help' gives option
- run-send-alarm.sh: Add your email here for receiving alarms
- run-log.sh: Add your email here for receiving logs
- run-log2.sh: Add your email here for receiving logs after each fill
- run-log3.sh:
- run-send-alarm-wd.sh
- finish_fill.sh: script executed after fill attempt
- run-gln-master.sh
- run-mail-que-view.sh
- run-time-sync.sh
- run-backup.sh
- run-tlog-and-plot.sh
- run-dlog-and-plot.sh
- run-mail-que-flush.sh
- run-view-master.sh: Output of the LN master process
LN configuration
The LN configuration file is found as ~/gln/gln.fig. It is self-explanatory. If this file got updated, use run-gln-ui.sh script and the command “load” in there. Note: After a “load” in the UI all detector fill schedules are gone! You need to do a “fill x y z after h:mm”.
ADC to channel mapping
Documentation for ADC mapping: connections_1_.pdf
- ADC 1-4: Manifold overflow 1-4 (Manifold overflow at supply box Q1-Q4)
- ADC 11-17: Fill overflow Q1-Q7 (Overflow input at supply box)
