  • 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, Fall 2017
Beam energy 10.6 GeV (5 pass)
Important: Document all your work in the logbook!

RC: Raffaella DeVita

  • (757) 575-7540
  • 9 575 7540 from Counting Room
  • devita@jlab.org

PDL: Eugene Pasyuk

  • (757) 876-1789
  • 9 876-1789 from Counting Room
  • pasyuk@jlab.org

Run Plan:

  • The first goal is to complete the beamline commissioning as described in [1]
  • Follow the plan thereby described accurately, recording every relevant information in the logbook

Plan:

Important Notes:

  1. During beam tune and harp scans Hall-B halo FSD must be masked.
  2. Do not run more than 60 minutes above 30 nA without the beam blocker in front of Faraday cup. Put beam blocker in for long running at high currents.
  3. If DAQ crashed/broken: Follow instruction on Documentation tab. If cannot resolved in 20-30 min call DAQ on-call cell phone.
  4. With any issue contact On-Call Experts or RC - do not spend more than 15-20 min trying to fix the problem.


General Instructions:

Locking up the hall

  • Work with the hall work coordinator (Doug Tilles or his designee) to make sure hall is ready for sweep at around 3pm:
    • Vacuum is good, magnet power supplies (Tagger and Torus) are turned ON and in remote mode, LCW is on.
  • Make sure experts, beamline, ECal, DC, HTCC, FTOF, and slow controls, checked their systems before the lockup.
  • When ready notify MCC to start sweep and lockup of the hall.
  • Make sure all necessary monitoring GUIs are up and running.
  • Make sure beam viewer screens are up.
  • When hall is in "Beam Permit"
    • Ramp torus to 10% of max current (380A)
    • Turn tagger magnet ON if beam tune on the tagger dump or tagger yoke dump will be needed (it will be needed if beam comes back after several hours of down)
    • Turn all beamline devices ON, turn all CLAS12 detectors OFF



Every Shift:

  1. Follow run plan as outlined by RC
  2. If any concern about beam stability, ask MCC if orbit locks are on (they should be).
  3. 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
  4. 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:

  1. Log screenshots of:
    • main scaler GUI display
    • Detector occupancy plots
    • Trigger rate gui
    • Beam strip charts
