• 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)

Shifts are canceled until 08:00 Monday March 19th

RC: Maxime Defurne

• (757) 575-7540
• 9 575 7540 from Counting Room
• mdefurne@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.

Run Plan: (last update 2/20 - 1:15 AM) When beam to Fraday Cup the Fast Shut Dow: Upstream, Midstream, Downstream, BOM and Solenoid shoudl be always Unmasked Always monitor the rates on the Halo counters when they are tuning beam to the other halls Do Not turn on or off SVT only SVT expert can do that Any request for special run change of configuration has to be approved by RC & documented In case of questions or uncertainties of what to do, please call the RC

General Instructions: For a given beam current, compute the FSD thresholds according to the Establish Physics Quality Beam document. Call MCC to update the values. Contact the beamline expert if there are questions about setting the FSD thresholds. The main lights in the Hall (dome lights) and the Forward Carriage lights are being kept off because of light leaks affecting some of the detectors. If these lights are switched on during an access, they should be switched off when leaving the Hall. Note that the dome lights when switched off cannot be turned back on immediately because they require 10-15 min to cooldown. Do not run more than 60 minutes above 30 nA with 5-pass beam without the beam blocker in front of Faraday cup. Put beam blocker in for long running at high currents for 5 pass operations. Turn DC HV off only for beam tuning; if no beam is available or when beam is stable, keep them on even if you are not taking data. In case of loss of communication with IOCBTARG, follow instructions at https://logbooks.jlab.org/entry/3502218 With any issue contact On-Call Experts or RC - do not spend more than 15-20 min trying to fix the problem. All jscaler iocs (iocjscalerX) on the health screen (under DAQ tab) must be restarted after every DAQ prestart is completed. Follow this link for detailed instructions https://userweb.jlab.org/~baltzell/CLAS12/SC/jlabScalersOps.txt Check that no unecessary beamline-related screens are open. This includes particularly the big beamline overview screen, but also and any motor/harp/collimator screens, and ioc health screens. Every Shift: Follow run plan as outlined by RC If any concern about beam stability, ask MCC if orbit locks are on (they should be). Keep shift summary up to date in HBLOG. Record all that happens. Check on white board all scalers, strip charts and monitoring plots that need to be logged regularly Document any beam condition change and send scaler GUIs to HBLOG Fill out BTA hourly. Click "Load from EPICS" to automatically fill the left side. Fill and submit the shift checklist in the logbook Perform 2H01A harp scan once per shift or when beam conditions have changed, based on beam monitors (BPMs, halo rates, beam-viewer). During harp scans the HV for DC and HTCC should be OFF. Every Run: Log screenshots of: main scaler GUI display Detector occupancy plots Trigger rate gui Beam strip charts FTCalo FADC scalers
