• 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: Axel Schmidt

• (757) 575-7540
• 9 575 7540 from Counting Room
• axelschmidt@gwu.edu

PDL: Valery Kubarovsky

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

• 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 2: Nominal beam positions: 2C24A (X=-2.0 mm, Y=0.6 mm) , 2H00 (X=-0.5 mm, Y=2.6 mm)

• 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:
  1. Notify MCC to request beam OFF and to drop Hall B status to Power Permit
  2. Call Engineering on-call
  3. 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
  4. Notify Run Coordinator
  5. Turn off all detectors

• Note 5: When the beam is being delivered to the Faraday Cup:
  1. the Fast Shut Down elements: Upstream, Midstream, Downstream, BOM, and Solenoid should always be in the state UNMASKED
  2. 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.

Run Plan: Nov 30 - Dec 1 2021 PROD66 and the trigger rgm_6GeV_inb_v1_0.trg, 100 M events (max 4 hours) per run. Continue production data on Carbon at 90 nA Dec. 1st. 7:30 AM machine will go down for a scheduled down time Swing/Day Shift Takers notify Dan Carman when Hall goes into controlled access Engineering/OPS will need ~1 hr access to tune 2H01 BPM to bring it back online ~1 hr will be needed to calibrate 2H01 (does not require access/ only beam) Check BPM positions after beam is returned We will keep the current Orbital lock on 2H00 until the end of Carbon Take beam away and move target to Empty position Lower beam current to 5 nA and perform harp scan, confirm with reference harp scans Move target back to Carbon Continue production on Carbon at 90 nA Hall Access Items (xxx): Dan Carman needs ~30 mins to replace components on CTOF Sergey need ~15 mins to replace FTOF cables DAQ configuration PROD66 , 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.

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. 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. 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 Every Run: Log screenshots of: (this is for the remote shifter, see dedicated Remote Shifts tab above.)
