CLAS12 Run Group M, Fall 20XX
Beam energy 20.6 GeV (10 pass)
Important: Document all your work in the logbook!

RC: Holly

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

PDL: Bob

• (757) 876-1789
• 9 876-1789 from Counting Room
• pasyuk@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 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 bad beam tune or bleed-through from other Halls.

• Note 2: At the end of each run, follow the standard DAQ restart sequence

"end run", "cancel", "reset", then if the run ended correctly, "download", "prestart", "iocjscalerRestartAll.sh", "go". If the run did not end correctly or if any ROCs had to be rebooted, "configure", "download", "prestart", "iocjscalerRestartAll.sh", "go".

After each step, make sure it is complete in the Run Control message window. If a ROC has crashed, find which one it is and issue a roc_reboot command and try again. Contact the DAQ expert if there are any questions.

• Note 3: Nominal beam positions: 2C24A (X=0.5 mm, Y=0.5 mm) , 2H01 (X=.6 mm, Y=.2 mm)

• Note 4: 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 5: 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 separate log entry with copies to HBTORUS and HBSOLENOID logbooks. In the "Notify" field add Ruben Fair, Probir Goshal, Dave Kashy and esr-users@jlab.org
  4. Notify Run Coordinator
  5. Turn off all detectors

• Note 6: When 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 7: Do not turn on the SVT or MM - only the SVT or MM expert can do that

• Note 8: Any request for a special run or change of configuration has to be approved by the RC & documented

• Note 9: Carefully check the BTA every hour and run the script btaGet.py to print for you what HAS TO BE in BTA for this hour. Edit BTA if it is incorrect.

• Note 10: Reset CLAS12MON frequently to avoid histogram saturation.

• Note 11: Shift workers must check the occupancies! Use this tool to compare to previous runs: https://clas12mon.jlab.org/mon12/histograms/

Run Plan: (Updated: Oct. 3 2018 at 14:30) Make sure that the FSD thresholds are set correctly and they are unmask when ready to receive beam to the FC As soon 2 nA run is finished notify Ben and Sergei that they can go to th hall When they finish the work in the hall continue to take data with 60 nA and 75 nA beams, 5M each The DAQ configuration for these runs is PROD66_PIN For each of runs, in addition to standard Beamline overview and monitoring plots, send to the logbook the DC HV, SVT currents. When Luminosity scan runs are finished, go to the production and take data with 45 nA beam. NOTE for this please use PROD66 configuration for DAQ. For every run please submit to the logbook all the screens listed in the "Every Run" section Andrea should call in between 8:00 - 8:30 in order to take special trigger runs for hadron trigger validation. The beam current should be 45 nA, and He will take care of the DAQ. With good beam it will take approximately 4-6 hours. Any questions call system expert, RC or PDL. Shift Worker Notes: From time to time, we might experience trigger bit issues (FT bits: 24, 25, 26, 27). Bit 26 might not trigger the alarm but when this issue happens it will count abnormally high. For the time being, shift leaders can try to do the sequence of End->Cancel->Reset, roc_reboot adcft1 (and adcft2, adcft3), make sure the ROCs are connected, then Download->Prestart->Go. If this does not work, repeat the sequence and add "Configure" in front of "Download". If the trig issue persists, continue to take production data without fixing it -- please make sure you log this infor in the RCDB "Comment" field. If the machine is down for few hours ask for low current first 5 nA make sure that the beam is stable both in position and current, check that the rates are OK on all the detectors and halo counters. Then ask for 40 nA and continue data for production. If there are issues with the beam call the RC. Sometimes MCC operator might ask to deliver tuned beam --- do not accept it. We need CW beam sent to the Faraday cup. If there is indeed a need for tuned beam, it should be sent to the tagger dump with the tagger magnet on. If you are uncertain, please call RC/PDL. Sometimes, a couple RICH channel scalers go to 0 and there is no alarm, even though the "# of fibers connected" would be shown to be the correct 138. Shift takers therefore should periodically, especially at the end of run, check the RICH scalers GUI. If there is an issue: For RICH recovery procedures, please see Log entry https://logbooks.jlab.org/entry/3562273. This would apply in the cases of 1. DAQ crash: rich4 is not responding or 2. RICH alarms (LV,missing tile, temperature etc). If it does not work or you are uncertain about what to do, contact the RICH expert on call. In case of other questions or uncertainties of what to do, call the RC

General Instructions: For a given beam current, compute the FSD thresholds according to the Establish Physics Quality Beam document. Call MCC to update the values. Contact the beamline expert if there are questions about setting the FSD thresholds. 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 an 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 cooldown. Do not run more than 60 minutes above 30 nA with 5-pass beam without the beam blocker in front of Faraday cup. Put beam blocker in for long running at high currents for 5 pass operations. Turn DC HV off only for beam tuning; if no beam is available or when 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 With any issue contact On-Call Experts or RC - do not spend more than 15-20 min trying to fix the problem. All jscaler iocs (iocjscalerX) on the health screen (under DAQ tab) must be restarted after every DAQ prestart is completed. Follow this link for detailed instructions https://userweb.jlab.org/~baltzell/CLAS12/SC/jlabScalersOps.txt 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. Reference harp scans: 2C21, 2C24, 2H01 Every Shift: Follow 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. Check on white board all scalers, strip charts and monitoring plots that need to be logged regularly Document any beam condition change and send scaler GUIs to HBLOG Fill out BTA hourly. Click "Load from EPICS" to automatically fill the left side.
