Shift Instructions
The Shifter's duty
For the Entire week:
  • Carry the cellphone and pager at all times. Remember to recharge the cell phone and check the pager battery. Spare batteries can be found in the cabinet in the control room
  • Place your name and office phone number on the whiteboard at IR2 for the period of your shift block
Once per day:
  • Check the daily lightpulser calibration. It is now part of the central calibration performed by the DAQ shifter. Check if the LP calibration has passed or failed. If it has failed, inspect the logfile which will be accessible from the E-logbook. Figure out why it failed (new bad channels since last calibration etc.) and notify the experts. You find the latest logfile here.
  • Check the EMC PIN Diode Voltage from the background panel during no beam. The baseline should be below 0.1 V. If this is not the case, contact Thomas Schietinger
Once per shift:
  • Check the electronics logbook for any problems regarding the EMC.
  • Look at OEP monitoring histograms
  • and investigate any problem you see. Use the electronics logbook to report any remarks about particular runs.
  • Look at OPR monitoring histograms
    There is also a Trace plot of pi0 mass and E/P (for the last 60 runs). Any change there should be reported to the calibration experts. Check recent runs for DQM comments using
     ~philiph/ebook/qaread -s emc -S 1
    (use option -h for more info).
  • Complete the EMC section in the electronic QA logbook for each run (instructions here).
  • Check JAS reference histograms and text to see if they are up-to-date, informing Huw Shorthouse if they are not.
    To run JAS with IR-2 set-up type:
  • Advise the BaBar shift of problems and fix them if possible. If necessary call in the experts.
Diagnose problems:
  • A list of known problems with solutions can be found under Troubleshooting . Have a look at this section before you start your shift. This will save you time in critical situations.
  • It is up to your own judgement when to call in the experts.
Emergency procedures:
Meetings to attend
  • 3:30 p.m. BaBar Operations meeting (Daily Mon-Fri, 9:30am on Saturday(check with run coordinator)), IR2 conference room. You are the main line of communication between BaBar operations and the EMC staff. It is your responsibility to relay any relevant information (planned beamless periods, MD periods, RODs etc.) to the experts that can be affected. If you cannot attend this meeting make sure somebody qualified takes your place!
  • 10:30 EMC meeting (Mon,Fri), Beehive (Friday) Sierra Room (Monday)
  • The EMC PIN DIODES are NOT seen as a EMC expert responsibility but lie in the domain of the PEPII liason shifter. You can nevertheless help by directing people to the right documentation
