CLAS12 Run Group M, Fall 2021
Beam energies: 2.1, 4.0, 6.0 GeV (1.96 GeV/pass)
Important: Document all your work in the logbook!

RC: Stepan Stepanyan

PDL: Valery Kubarovsky




Run Plan: Nov 10 - 12 2021

  • Restore physics quality beam for the production running at 3-pass, start from the tagger dump (see instructions [1])
  • After physics quality beam is established to the Faraday cup dump, proceed with the following:
    • Establish produciton current for LH2 target (limit 80 nA), run DAQ with the produciton trigger Config. PROD66 , trigger rgm_6GeV_inb_v1_0.trg )
    • Trigger Validation Runs with the established conditions:
  1. Random trigger @30 kHz 4 hours with the trigger rgm_6GeV_inb_RNDM_30kHz_v1_0.trg
  2. Trigger without DC roads: 1 hour with the trigger rgm_6GeV_inb_No_Dc_Roads_v1_0.trg
  • Production data taking with rgm_6GeV_inb_v1_0.trg 2 hour runs



Shift Worker Notes:

In case of other questions or uncertainties of what to do, call the RC or PDL

General Instructions:

  • 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 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 cool down.
  • Do not run more than 30 minutes with >150 W beam to Faraday cup without the beam blocker.
  • Turn DC HV off only for beam tuning; if no beam is available or when the 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
  • 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 the 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.
  • 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 then correct as needed.
  • Fill and submit the shift checklist in the logbook

Every Run:

  • Main beamline GUI overview
  • clas12mon Detector occupancy plots
  • Trigger rate GUI
  • FT-Cal FADC scalers
