CLAS12 Run Group M, Fall 2021

Beam energies: 2.1, 4.0, 6.0 GeV (1.96 GeV/pass)

RC: Susan Schadmand and Sebastian Kuhn

• Susan Schadmand (757) 575-7540, susansch@jlab.org
• Sebastian Kuhn (757) 639-6640, kuhn@jlab.org
• 9 575 7540 from Counting Room

PDL: Valery Kubarovsky

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

Run Plan: Jan 31, 2022

Production runs use PROD67_noVTPread and the trigger rgm_6GeV_inb_v1_0.trg .
Run duration 100M events or 4 hours, whichever comes first.

• status: 6GeV beam, LAr target is full, Beam blocker is OUT
• Note to self: Presently, the alarm limit for the beam_stopper_alarm is raised for running without beam blocker .
  • Needs to be restored to 'normal' value for the solid targets where we need to run with the beam blocker IN.

• running: 25nA LAr for 2 days

• next:
  • single tin foil for 2 days, beam blocker IN
  • Ca48 target, beam blocker IN

DAQ configuration

PROD67_noVTPread , production trigger rgm_6GeV_inb_v1_0.trg .

NOTE: UNLESS a RICH problem crashes the DAQ, do NOT interrupt an otherwise smooth run to do a RICH recovery - instead do this in between runs.

NOTE: BOTH the shift expert AND the shift worker MUST check monitoring histograms at least once every 30-60 minutes to make sure there are no major detector problems.

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.

Reference Monitoring Histograms (6 nA, production C) [4] Old reference Monitoring Histograms (50 nA, production LD2) [5]

Counter rates

• Upstream counters integrated rates: 0-15 Hz (acceptable up to 100 Hz are acceptable) @50 nA.
• 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.

NOTE: BOTH the shift expert AND the shift worker MUST check monitoring histograms (mon12) at least once every 30-60 minutes to make sure there are no major detector problems.

Notes Some plots in mon12 have a choice of histogram sets per sector, select buttons at the bottom of the plot. Only the currently selected set ends up in the logbook entry. that means you have to look at all sectors for these histograms LTCC is NOT used in this experiment. HV should be kept OFF. FMT only using 3 FMT layers, not 6. If we do a RICH recovery, we have to restart the DAQ. This is not a problem it is a fact, https://logbooks.jlab.org/entry/3980363 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. 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. 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 Do not run more than 30 minutes with >150 W beam to Faraday cup without the beam blocker, eg https://logbooks.jlab.org/entry/3979277 Any request for a special run or change of configuration has to be approved by the RC & documented Do not turn OFF FTOF HVs, even during the beam tune with CW beam (turn off if tuned/pulsed beam in the upstream beamline) 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. Reset the online monitoring histograms frequently to avoid histogram saturation. 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 If responding to RICH or Trigger alarms please post screens also to RICH or HBTRIGGER logbook, respectively.

Known Issues DAQ when starting a run, it can happen that the live time alarm goes off, can be acknowledged DAQ the trigger alarm goes off when the trigger rate is too small or too high or a sector is not triggering at all. If necessary, the shift expert can "Set All Normalized Rate Limits" at useful rates (not too low) DAQ ROC rate tdcecal4 is double wrt the 5 other sectors, https://logbooks.jlab.org/entry/3979286 DAQ The error messages " ERR: event# ..." e.g. for crates tdcband1, tdcecal1 and tdcecal6 are NOT a problem PCAL transient: mu strip occupancy hole in U view TDC, https://logbooks.jlab.org/entry/3978499, https://logbooks.jlab.org/entry/3978736 ECAL one strip of TDC ECout W strip sector4 is hot, https://logbooks.jlab.org/entry/3979286 ECAL HV SEC2_WI_E36 is known to be problematic. Channel stays off for now. BMT off: occupancy Z, layer 3, sector 1, detetcor 7, S1L3 strip HV is off due to high leakage, https://logbooks.jlab.org/entry/3970886 BMT off: occupancy Z, layer 5, sector 2, detetcor 14 RICH when a tile is missing in the spectra, wait till the end of the run and then do RICH recovery RICH FPGA temperatures can show yellow tiles. Yellow tiles in the RICH temperature map are normal. It is done just to pay attention to the tiles with temp>70 degrees. The alarm is set to 75 degrees https://logbooks.jlab.org/entry/3975547 IOCBTARG In case of loss of communication, 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.

NOTE: BOTH the shift expert AND the shift worker MUST check monitoring histograms at least once every 30 - 60 minutes to make sure there are no major detector problems. Follow the [Short Term Schedule] as outlined by RC includes Run Plan, DAQ configuration, and References and Standards Keep shift summary up to date in HBLOG. Record all that happens. Cycle the FMT gas once per shift, in-between runs. Pease log in shift summary. If it is not reset, the interlock may drop and disable the HV. 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. Do a RICH recovery (press the RICH Recovery button on the GUI) once daily during day shift, between runs. Please log in shift summary. Note the automated "RICH Recovery" sequence already confirms RICH4 is up and accepting ssh connections before claiming success. And it also prints out that you have to "Cancel->Reset->Configure->Download->Prestart" before starting the next run. Fill out BTA hourly. Click "Load from EPICS" to automatically fill the left side then correct as needed. Accelerator beam time: ABU: acceptable beam used (eg harp scans, calibrations, trigger settings, running) BANU: beam acceptable but not used (eg radiator change or our problems) BNA: beam not acceptable (eg tuning, drifting, not focused) Experiment beam time ER: experiment ready PCC: planned configuration change (when beam is masked while radiators are moved, DAQ (roc rebooting, restarting runs)), if more than 5 minutes, put a short comment, eg harp scans or DAQ. UED: unplanned experiment down (hardware failure) In case of other questions or uncertainties of what to do, call the RC or PDL (remote) shift worker: see dedicated Remote Shifts tab above.
