MONITORING VIA STAR SLOW CONTROLS

Screenshots: slowcontrols.jpg,  tof_top.jpg,  tofgas.jpg

1. Use STAR Slowcontrols monitor to check TOFr HV: Go to slow controls terminal and click on TOF->TOFrGAS->P (see slowcontrols.jpg)

   or open as user "sysuser" an xterminal on sc3.starp and start the TOF alarm handler "tof_top" (see tof_top.jpg) and click on "TOFr HV Monitor" (see tofgas.jpg)

2. watch the unix timestamp update (should do so 1/minute) and check that the Freon flow is around 62ccm and the Isobutane flow around 3.5ccm.  The SF6 flow is physically disconnected bu still might show some 0.15ccm readout.  The important Isobutane Ratio and SF6 Ratio should be either 1 or (for the SF6 Ratio) very close to 0.
   
3. When these ratios are higher than 1 for more than 1 minute audible Yellow or Red SC alerts will ring and approriate action is required: in case of Yellow Alert  go to the Gas Mixing Room and read the pressure gauges and flow meters. Contact the TOF Gas Expert and  the TOFp Detector Expert list (tofp@tofp.physics.rice.edu) immediatly and report those numbers. In case of Red Alert, immediatly switch of the TOFrHV (see link), and stop the Isobutane gas flow by closing its flow controller.
   

MONITORING VIA TERMINAL ACCESS

Screenshots:

1. Sit in front of the TOFp Control PC, and open a unix terminal window. Then ssh to the machine tofgas.star (the password is posted there). Or, in case of network interruptions, go to the tofgas terminal in the Gas Mixing room and log on with the standard user/password combination.
   
2. Check whether the TOFr HV monitoring daemon is running by typing

   crontab -l

   The output should look like this:

   
   [tofp@tofpdaq ~]% crontab -l
   # DO NOT EDIT THIS FILE - edit the master and reinstall.
   # (gasmon.cron installed on Tue Feb 11 21:23:15 2003)
   # (Cron version -- $Id: crontab.c,v 2.13 1994/01/17 03:20:37 vixie Exp $)
   # -- TOFr GasMonitor Cron Job
   #
   # run every minute
   * * * * *     $HOME/bin/gasmon -readout >> /data/tofr/gasmon.log
    	

3. if the cron job  (gasmon) is not running, contact the TOFp Gas or Detector Experts (tofp@physics.rice.edu)
4. To check the history of the gas flow readouts readouts, use the command

   tail /data/tofr/gasmon.log

   The output typically looks like the following, where the columns represent: time stamp , Freon, Isobutane and SF6 gas flows followed by the isobutane/freon and SF6/freon  ratios. All the flows are in ccm,  and the ratios are normalized to 1.

   
   [tofp@tofgas ~]$ tail /data/tofr/gasmon.log
