If calling local numbers (with area code prefix 757) from the counting room dial 9+[last 7 digits]. To call other area codes dial 91+[10 digit number]

- 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
Run is Over!
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 -
- Notify MCC, request beam OFF and drop Hall status to Power Permit
- Call Engineering on-call
- 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
- Notify Run Coordinator
- Call the MM expert to turn the detector off
- Call SVT expert to turn SVT off
- Turn off all the other detectors
- Note 6: When beam is being delivered to the Faraday Cup -
- the Fast Shut Down: Upstream, Midstream, Downstream, BOM and Solenoid should be always Unmasked,
- 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: May3-May 6May 4 (Day/Swing) There are a series of special runs planned. 1. FT-only trigger runs: Genova group (Raffaella/Andrea) just finished this run 2. Random-trigger with existing PCAL/FTOF map: Started around 9am and should conclude around 2pm. If there is any issue, contact Andrea via bluejeans.com/1342978709 For 3--5, Sergey will take control of DAQ 3. DAQ studies(Sergey): Starting from 2:00pm. Sergey must be notified around 1:30pm if he is not already in the counting house. This is a series of short runs 4. DC/Varying readout window size/current scans: This will be a series of short runs (~30min each). For exact setting, please contact Volker (phone # on white board); Sergey will implement the changes. 5. Mode 7: Sergey will perform this run (~2 hrs). Dan should be contacted if needed via FTOF expert phone. May 4(Swing) --- May 6th (Owl) When the above special runs are finished. Resume production runs at 50nA with trigger_v12_3.cnf
May 6 at 5 am MCC will terminate beam delivery. Start preparation for summer shutdown after that
A small reception full of fancy food will be held in the counting house at 7am for the early birds. No reservation needed. Dress code: photo-friendly.
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.
