  • 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 M, Summer 2020
Beam energies: 1.1, 2.2, 4.4, 6.6 GeV (1.1 GeV/pass)
Important: Document all your work in the logbook!

RC: Someone

PDL: XXXXX



Run Plan:

  • Any questions call system expert, RC or PDL.

Shift Worker Notes:

<--

  • From time to time, we might experience trigger bit issues (FT bits: 24, 25, 26, 27). Bit 26 might not trigger the alarm but when this issue happens it will count abnormally high. For the time being, shift leaders can try to do the sequence of End->Cancel->Reset, roc_reboot adcft1 (and adcft2, adcft3), make sure the ROCs are connected, then Download->Prestart->Go. If this does not work, repeat the sequence and add "Configure" in front of "Download". If the trig issue persists, continue to take production data without fixing it -- please make sure you log this infor in the RCDB "Comment" field.
  • If the machine is down for few hours ask for low current first 5 nA make sure that the beam is stable both in position and current, check that the rates are OK on all the detectors and halo counters. Then ask for 40 nA and continue data for production. If there are issues with the beam call the RC. Sometimes MCC operator might ask to deliver tuned beam --- do not accept it. We need CW beam sent to the Faraday cup. If there is indeed a need for tuned beam, it should be sent to the tagger dump with the tagger magnet on. If you are uncertain, please call RC/PDL.
  • Sometimes, a couple RICH channel scalers go to 0 and there is no alarm, even though the "# of fibers connected" would be shown to be the correct 138. Shift takers therefore should periodically, especially at the end of run, check the RICH scalers GUI. If there is an issue:
    • For RICH recovery procedures, please see Log entry https://logbooks.jlab.org/entry/3562273. This would apply in the cases of 1. DAQ crash: rich4 is not responding or 2. RICH alarms (LV,missing tile, temperature etc). If it does not work or you are uncertain about what to do, contact the RICH expert on call.

--> In case of other questions or uncertainties of what to do, 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 unnecessary 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.
  • Reference harp scans: 2C21, 2C24, 2H01

--> 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

Every Run:

Log screenshots of:

  • main scaler GUI display
  • Detector occupancy plots
  • Trigger rate gui
  • Beam strip charts
  • FTCalo FADC scalers
