• 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: Stepan Stepanyan

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

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=-2.2 mm, Y=0.7 mm) , 2H01 (X=0.9 mm, Y=-0.3 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.

Run Plan: Nov 10 - 12 2021 A 3-pass, 5,986 GeV beam, LD2 target Establish 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: Fill the target with LH, see instructions at [2] and turn ON CLAS12 detectors Ask for 10 nA beam, check if rates in the detectors are reasonable ** Establish production current for LD2 target (limit 70 nA), run DAQ with the production trigger Configuration PROD66 , trigger rgm_6GeV_inb_v1_0.trg and increase beam current to 70 nA with steps of 10 nA. At every step record detector and DAQ rates (dump GUIs into logbook), run the monitoring, and record DC R1 occupancy. After the run is done (went up to 70 nA), call Valery on the PDL phone. Production data taking with Config. PROD66 and rgm_6GeV_inb_No_Dc_Roads_v1_0.trg 100 M events (max 2 hours) per run. Note: if Valery will provide a new trigger file with Sector 6 no HTCC, use that file for the production runs Low luminosity run for SVT threshold studies - Yuri Gotra After the low Lumi run will start target change, from LH2 to LD2, will take up to 8 hours. The solenoid will be ramped down. Hall Access Items (Friday, November 12 at 10 am): HTCC (Youri) CTOF, cable repair (Daniel) DAQ configuration PROD66 , production trigger rgm_6GeV_inb_v1_0.trg At the end of each run, follow the STANDARD DAQ RESTART SEQUENCE This needs to be followed at the end of every run. Note: this might be different from the instructions coming up on RunControl. "end run", "cancel", "reset" if the run ended correctly: "download", "prestart", "go" if the run did not end correctly or if any ROCs had to be rebooted: "configure", "download", "prestart", "go" After each step, make sure it 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 tab above.)
