• 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 A, Spring 2018
Beam energy 10.6 GeV (5 pass)
Important: Document all your work in the logbook!
Remember to fill in the run list at the beginning and end of each run (clas12run@gmail.com can fill the run list)

RC: Lei Guo

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

PDL: Eugene Pasyuk

• (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 UPSTREAM counters has to be in the range 0-15 Hz (rates up 100 Hz are acceptable) and MIDSTREAM has to be in the rage 10-20 Hz (acceptable up to 50 Hz) @50 nA. Count rates in the range of hundreds or more may indicate bad beam tune or bleed-through from other Halls.

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

"end run", "cancel", "reset", then

if run ended correctly "download", "prestart", "iocjscalerRestartAll.sh", "go".

if run did not ended correctly, or ROCs had to be rebooted "Configure", "download", "prestart", "iocjscalerRestartAll.sh", "go".

After DAQ prestart is complete reboot the scaler IOCs with the command: iocjscalerRestartAll.sh.

Note: 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,Y=0.5) , 2H01 (X=1.0 mm, Y=-1.0 mm) see log entry https://logbooks.jlab.org/entry/3570290.

• Note 4: Do not turn OFF FTOF HVs, even during the beam tune

• Note 5: In case of the Torus and/or Solenoid Fast Dump do the following -
  1. Notify MCC, request beam OFF and drop Hall status to Power Permit
  2. Call Engineering on-call
  3. Make separate log entry with copies to HBTORUS and HBSOLENOID logbooks. In the "Notify" filed add Ruben Fair, Probir Goshal, Dave Kashy and esr-users@jlab.org
  4. Notify Run Coordinator
  5. Call the MM expert to turn the detector off
  6. Call SVT expert to turn SVT off
  7. Turn off all the other detectors

• Note 6: When beam is being delivered to the Faraday Cup -
  1. the Fast Shut Down: Upstream, Midstream, Downstream, BOM and Solenoid should be always Unmasked,
  2. No changes to the FSD threshold without RC or beamline expert approval.

• Note 7: Do not turn on or off SVT - only SVT expert can do that
• Note 8: Any request for a special run or change of configuration has to be approved by RC & documented.
• Note 9: Check carefully BTA every hour and run script btaGet.py . It will 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.

Run Plan: May2-May 6 May 2(Day) - May 6 (Owl) Take production data with trigger_v12_3.trg @ 50nA on LH2 target, 100 M per run (no longer than 3 hours) till Wednesday morning, May 2nd. May 2nd (Day Shift). Continue produciton data taking until 9:00AM, when the beam will be taken away for RF recovery as well as preparation for the tour (1pm). Once the beam is down, request MCC to send survey team to open the hall for restricted access. Call Yuri to turn off the SVT HV. Shift workers should turn the HV off the trackers (MVT, FTT) and DC. Once this is done, call PDL or Denny or Hall B engineering on call to ramp down the magnet. Notify Sergey/Ben (DAQ) in case they need to switch the FADC->VTP board to address the FT trigger bits issues. The tour is scheduled at 1pm. Once the tour is over, please notify MCC for to sweep and close the hall. In the mean time, call PDL/Denny/Hall B engineering on call to ramp the magnet back up. Once magnet is up, call Yuri to turn SVT back on. Shift workers should then turn DC/MVT/FTT back on. Request 5nA CW beam first to be sent to Faraday cup. Verify that the FTC asymmetry is low, and the beam positions are good. Then increase the beam current to 50nA. Remind MCC what our required positions are ("Note 3" above) if you see any deviation/drift. Resume production data taking once beam is good. If the above failed, follow the procedure for reestablishing the beam and notify RC and beamline expert. May 2nd (Day/Swing) -- May 6th (Owl) Continue produciton data taking. From time to time, we might experience trigger bit issues (FT bits: 24, 25, and 26 and 27). bit 26 might not trigger the alarm but when this issue happens it will count abnormally high pre-prescale. For the time being, shift leaders cand try to do the sequence of End->Cance->Reset, ro_reboot adcft1 (and adcft2, adcft3), make sure the roc are conencted, then Download->Prestart->Go. If this does not work, repeat the sequence and add "Configure" in front of "Download". If the trig issue persist, please continue take production data without fixing it -- please make sure you log this infor in the RCDB "Comment" field. The underlying issue will be addressed on Monday. 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 50 nA and continue data for production. If there are issues with the beam call the RC. Sometimes MCC operator might ask to deliver tune beam --- please do not accept it. We need CW beam sent to the Faraday cup. If there is in deed a need for tune beam, it should be sent to the tagger dump with the tagger magent on. If you are uncertain, please call RC/PDL. Please contact the Micromegas (BMT, FMT & FTT) expert if there are trips, or if you notice any issues in the online monitoring. Do not turn OFF or ON the MM only the expert can do that. See Log entry https://logbooks.jlab.org/entry/3556528 Sometimes, a couple of RICH channel scalers would go to 0 and there is no alarm, even though the "# of fjibers 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, please refer to the instruction below. 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, please contact the RICH expert on call In case of other questions or uncertainties of what to do, please 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 unecessary 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 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.
