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

RC: Stephen Bueltmann

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

PDL: Eugene Pasyuk

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

Run Plan: Dec 15 - Dec 21 2021

PROD67_noVTPread and the trigger rgm_6GeV_inb_v1_0.trg.
Run duration should be no more than 100M events or 4 hours, whichever comes first.

Summary

• Take 2H data at 50 nA
• Friday 7:30, switch to 4He target
  • call MCC and ask for Controlled Access
  • warm up target with set point = 100 K
• Establish beam, probably during the second half for day shift
  • follow procedures to restore beam
  • check DC occupancy at 60 nA
  • check beam blocker calibration
  • take data at 60 nA until the end of 2021 run
• 2021 data taking ends on Tuesday, December 21, at 7:00

DAQ configuration PROD67_noVTPread , production trigger rgm_6GeV_inb_v1_0.trg 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. Announcements If any weird stripes appear in the DC occupancy plots, call Sergey. This is a known problem. Note 1: Be very mindful of the background rates in the halo counters, rates in the detectors, and currents in the SVT for all settings to ensure that they are at safe levels. The integrated rates on the upstream counters have to be in the range 0-15 Hz (rates up to 100 Hz are acceptable) and the rates on the midstream counters have to be in the range 10-20 Hz (acceptable up to 50 Hz) @50 nA. Counting rates in the range of hundreds of Hz may indicate a bad beam tune or bleed-through from other Halls. Note 3: Do not turn OFF FTOF HVs, even during the beam tune with CW beam (turn off if tuned/pulsed beam in the upstream beamline) Note 4: In case of a Torus and/or Solenoid Fast Dump do the following: Notify MCC to request beam OFF and to drop Hall B status to Power Permit Call Engineering on-call Make a separate log entry with copies to HBTORUS and HBSOLENOID logbooks. In the "Notify" field add Probir Goshal, Dave Kashy, and esr-users@jlab.org Notify Run Coordinator Turn off all detectors Note 5: When the beam is being delivered to the Faraday Cup: the Fast Shut Down elements: Upstream, Midstream, Downstream, BOM, and Solenoid should always be in the state UNMASKED No changes to the FSD threshold should be made without RC or beamline expert approval Note 6: Any request for a special run or change of configuration has to be approved by the RC & documented Note 7: * Fill out BTA hourly. Click "Load from EPICS" to automatically fill the left side then correct as needed. Note 8: Reset CLAS12MON frequently to avoid histogram saturation. Note 9: If crate ADCBAND was rebooted: Contact BAND expert and make a note in the HBBAND logbook and in HBLOG. Note 10: ECAL HV SEC2_WI_E36 is known to be problematic. Channel stays off for now. Note 11: LTCC is NOT used in this experiment. HV should be kept OFF. Note 12: If responding to RICH or Trigger alarms please post screens also to RICH or HBTRIGGER logbook, respectively. Note 13: Do a RICH recovery (press the RICH Recovery button on the GUI) once daily during the day shift between runs. Note 14: Cycle the FMT Gas once per shift. If done rapidly without pausing (Gas "stop"-"yes"-"start"-"yes"), the HV should not crash.

Beamline vacuum: should be not higher than 5e-5.

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. Refer to these photos! ON: [6] OFF: [7] 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. 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 and submit the shift checklist in the logbook Cycle the FMT gas once per shift in-between runs! Turning off and on the gas flow without pausing to avoid HV trips. If the HV tripped, make sure that once gas flow is restarted and the flow differential is down to reasonable values, to turn the FMT HV back on and let it ramp all the way up. Remember that this experiment is only using 3 FMT layers, not 6. Every Run: Log screenshots of: (this is for the remote shifter, see dedicated Remote Shifts tab above.)
