- Note, all non-JLab numbers must be dialed with an area code. When calling from a counting-house landline, dial "9" first.
- To call JLab phones from outside the lab, all 4-digit numbers must be preceded by 757-269

CLAS12 Run Group A, Winter 2018
Beam energy 10.6 GeV (5 pass)
Important: Document all your work in the logbook!
Remember to fill in the run list at the beginning and end of each run (clas12run@gmail.com can fill the run list)
RC: Rafayel Paremuzyan
- (757) 575-7540
- 9 575 7540 from Counting Room
- rafopar@jlab.org
PDL: Eugene Pasyuk
- (757) 876-1789
- 9 876-1789 from Counting Room
- pasyuk@jlab.org
- Note 1: Be very mindful of the background rates in the halo counters, rates in the detectors, and currents in the SVT for all settings to ensure that they are at safe levels.
- Note 2: At the end of each run, follow the DAQ restart sequence "end run", "abort", "reset", "download", "prestart", "go". After DAQ prestart is complete reboot the scaler IOCs with the command: iocjscalerRestartAll.sh. Note: After each step, make sure it is complete in the Run Control message window. If a roc has crashed, find which one it is and issue a roc_reboot command and try again. Contact the DAQ expert if there are any questions.
- Note 3: Nominal beam positions: 2H01 (X=1.0 mm, Y=-1.5 mm)
- Note 4: With beam to the Faraday Cup, typical rates on all halo counters upstream from the target should be either 0 or of the order of few counts. Count rates in the range of tens or more may indicate bad beam tune or bleed-through from other Halls.
