CLAS12 Run Group C, Summer 2022

Daily RC Meetings at X:00: https://zozoom.asdf

RC: Sebastian Kuhn

  • (757) 575-7540 or
  • (757) 639-6640

PDL: Eugene Pasyuk

  • (757) 876-1789

Run Plan: June 2022

Production runs use PROD67_noVTPread and the trigger rgm_6GeV_inb_v1_0.trg

Run duration 100M events or 4 hours, whichever comes first.

  • run 6GeV 80 nA on Ca48 target (240 mg/cm2), beam blocker IN, until SAD
  • low luminosity runs:(ca 3pm - 9pm on Feb 7)
    • 2 hrs 5nA
    • 2 hrs 10 nA
    • 2 hrs 40 nA
  • the run on Ca48 until 6am, Feb 8
  • 6am Feb 8: Investigate BLA tune beam trips with tune beam to Hall B, https://devweb.acc.jlab.org/CSUEApps/atlis/task/24015
  • RC will be there at 6 am and follow Eugene's instruction
    • put the blank collimator in
    • turn HV off for all tracking detectors, just in case if the tagger magnet trips during the test
    • MCC may mask upstream halo FSD if necessary but keep all other FSD unmasked

DAQ configuration

  • Configuration PROD67_noVTPread, trigger file rgm_6GeV_inb_v1_0.trg
  • NOTE: UNLESS a RICH problem crashes the DAQ, do NOT interrupt an otherwise smooth run to do a RICH recovery - instead do this in between runs.
  • NOTE: BOTH the shift expert AND the shift worker MUST check monitoring histograms at least once every 30-60 minutes to make sure there are no major detector problems.
  • At the end of each run, follow the STANDARD DAQ RESTART SEQUENCE:
    • "end run", if the run ended correctly then: "prestart", "go"
    • if the run did not end correctly or if any ROCs had to be rebooted:
      • "cancel", "reset"
      • "configure", "download", "prestart", "go"
  • After each step, make sure it is completed in the Run Control message window. If a ROC has crashed, find which one it is, issue a roc_reboot command ON JUST THAT ROC and try again. Contact the DAQ expert if there are any questions.

References and Standards

Nominal Beam Positions

  • 2H01, X: -0.6 mm, Y: 0.8 mm
  • 2C24, X: -2.0 mm, Y: +0.6 mm

FSD Thresholds

  • Upstream: 2000 Hz
  • Midstream: 2000 Hz
  • Downstream: 500000 Hz
  • BOM: 10000
  • 5 ms dwell time

Reference Harp Scans for Beam on Faraday Cup 2H01 [1]

Reference Harp Scans for Beam on Tagger dump 2C21 [2], tagger harp [3]

Reference Monitoring Histograms

Counter rates

  • Upstream counters integrated rates: 0-15 Hz (acceptable up to 100 Hz are acceptable) @50 nA.
  • Midstream counters: 10-20 Hz (acceptable up to 50 Hz) @50 nA.
  • Counting rates of ~ hundreds of Hz may indicate bad beam tune or bleed-through from other Halls.


NOTE: BOTH the shift expert AND the shift worker MUST check monitoring histograms at least once every 30 - 60 minutes to make sure there are no major detector problems.

  • Follow the [Short Term Schedule] as outlined by RC
    • includes Run Plan, DAQ configuration, and References and Standards
  • Keep shift summary up to date in HBLOG. Record all that happens.
  • Do a RICH recovery (press the RICH Recovery button on the GUI) once daily during day shift, between runs. Please log in shift summary.
    • Note the automated "RICH Recovery" sequence already confirms RICH4 is up and accepting ssh connections before claiming success. And it also prints out that you have to "Cancel->Reset->Configure->Download->Prestart" before starting the next run.
  • Fill out BTA hourly. Click "Load from EPICS" to automatically fill the left side then correct as needed.
    • Accelerator beam time:
      • ABU: acceptable beam used (eg harp scans, calibrations, trigger settings, running)
      • BANU: beam acceptable but not used (eg radiator change or our problems)
      • BNA: beam not acceptable (eg tuning, drifting, not focused)
    • Experiment beam time
      • ER: experiment ready
      • PCC: planned configuration change (when beam is masked while radiators are moved, DAQ (roc rebooting, restarting runs)), if more than 5 minutes, put a short comment, eg harp scans or DAQ.
      • UED: unplanned experiment down (hardware failure)


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

(remote) shift worker: see dedicated Remote Shifts tab above.


Tasks

Every Run:

  • With beam present, log screen shots of:
    • Beamline Overview, in VNC or Web Browser
    • CLAS12 Trigger rates and DAQ status

Every Shift:

  • Fill the shift checklist
  • Log screen shots of RICH temperature and scaler maps. Log in HBLOG and RICH logbook.

Regularly:

  • reset & check spectra frequently (every 30 - 60 minutes)
    • Some plots in mon12 have a choice of histogram sets per sector, select buttons at the bottom of the plot. Only the currently selected set ends up in the logbook entry.
    • that means you have to look at all sectors for these histograms
