CLAS12 Run Group C, Summer 2022

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

RC: Jane Doe

• (757) 575-7540

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.

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.

Zoom for 24-7 communication with counting house: https://jlab-org.zoomgov.com/j/1619881100 Passcode REQUIRED: 927417 Remind the expert in the counting house to restart their zoom, if necessary Remote VNC connection instructions: https://logbooks.jlab.org/entry/3906039 All necessary applications should be avaible from the desktop menu (left/right click on the desktop) EPICS GUIs should be accessed ONLY via the desktop menu or by running clascss-remote. Remote Demonstration Video (150 MB) Tasks Every Run: With beam present, log screen shots of: Beamline Overview, in VNC or Web Browser CLAS12 Trigger rates and DAQ status upload monitoring plots (mon12) to logook look at the spectra: Reference, current, and 5 most recent runs, choose a reference run (the reference numbers refer to logbook entries): 6 GeV 80 nA on Ca48 https://clas12mon.jlab.org/mon12/histograms/?reference=3982817 6 GeV 90 nA on Sn https://clas12mon.jlab.org/mon12/histograms/?reference=3980929 ref 6 nA, production C, https://clas12mon.jlab.org/mon12/histograms/?reference=3973807 ref 50 nA, production LD2, https://clas12mon.jlab.org/mon12/histograms/?reference=3943458 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 in Web Browser: Upstream/Midstream Halo Counters, Downstream Halo Counters, Beam Currents, BPM Positions
