- 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 Engineering Run, 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)

- 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: 2C21 (X=0.0 mm, Y=0.0 mm), 2C24 (X=0.0 mm, Y=0.7 mm), 2H01 (X=0.3 mm, Y=-0.6 mm)
- Note 4: With beam to the Faraday Cup, typical rates pn 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.
Run Plan:(last update 2/4 - 14:30) All studies will take data at 100% torus field (negatives inbending) and 100% solenoid field (positive polarity on supply). The beam position should be as indicated above. Make sure FSD thresholds are set correctly for whatever current is selected (refer to instructions in the "Establish-physics quality beam" procedure at [1]), integration time is set to 5 ms, and that the orbit locks are on.
