CLAS12 Run Group K, Fall 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: Annalisa D'Angelo
- (757) 575-7540
- 9 575 7540 from Counting Room
- annalisa@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 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", "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 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=0.2 mm, Y=0.2 mm) , 2H01 (X=0.3 mm, Y=-0.9 mm)
- Note 4: Do not turn OFF FTOF HVs, even during the beam tune with CW beam (turn off when doing a Moller run or if there is tuned/pulsed beam in the upstream beamline)
- Note 5: 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 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
- Notify Run Coordinator
- Turn off all detectors
- Note 6: When 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
- Note 7: Any request for a special run or change of configuration has to be approved by the RC & documented
- Note 8: 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 9: Reset CLAS12MON frequently to avoid histogram saturation.
- Note 10: Shift workers must check the occupancies! Use this tool to compare to previous runs: https://clas12mon.jlab.org/mon12/histograms/
- Note 11 Do not Turn OFF MVT HV: Instead go to 'Restore settings' from the MVT overview screen:
- SafeMode.snp for beam tuning and Moeller runs
- MV_HV_FullField.snp for full solenoid field
- MV_HV_MidField.snp wgeb solenoid < 4T
- NOTE 12 Check the vacuum periodically, make sure vacuum id not higher than 5e-5
- NOTE 13 Always reset the CFD threshold after all power off/on on the CFD crate
After the CAMAC crate 1 holding the CND CFD boards is switched off for any reason, it is mandatory to reset the associated thesholds typing the following command from any clon machine terminal:
>> $CODA/src/rol/Linux_x86_64/bin/cnd_cfd_thresh -w 0
- NOTE 14: As of 10/25, the issue of detector scalers being frozen and starting a new run has been resolved. Shift workers should anyway check routinely scalers to verify they update correctly and make a logbook entry if anomalies are observed after starting a new run.
- NOTE 15: To solve common SVT issues see https://logbooks.jlab.org/entry/3615766
