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+[ten 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

Jan 27 - 29, 2022
4GeV 22nA on LAr
Run Plan: Jan 30 - 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.
- LAr target is empty, cell stays in position, Beam blocker IN
- Empty target run
- FC calibration (4GeV) is done
- Take 2 hours of empty target run at 150 nA
- Carbon target (single foil 2 mm) IN
- FC calibration for C target is loaded
- Run with 90 nA
- Monday pass change (6GeV beam)
- Need to establish quality beam, repeat beam centering, beam blocker calibration.
- OUTLOOK: Run on Ar, Sn and C with 6 GeV beam
DAQ configuration
PROD67_noVTPread , production trigger rgm_6GeV_inb_v1_0.trg .
NOTE: BOTH the shift expert AND the shift worker need to check monitoring histograms at least once every 1-2 hours 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.

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.
