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 M, Fall 2021
Beam energies: 2.1, 4.0, 6.0 GeV (1.96 GeV/pass)
Important: Document all your work in the logbook!
RC: Larry Weinstein
- (757) 575-7540
- 9 575 7540 from Counting Room
- weinstei@jlab.org
PDL: Eugene Pasyuk
- (757) 876-1789
- 9 876-1789 from Counting Room
- pasyuk@jlab.org
Run Plan: Dec 10 - Dec 14 2021
PROD67_noVTPread and the trigger rgm_6GeV_inb_v1_0.trg, Run duration should be no more than 100M events or 4 hours, whichever comes first.
Summary
- Tuesday day: install 2H target
- follow procedures to restore beam
- check DC occupancy at 50 nA
- check beam blocker calibration
- take data at 50 nA
- Friday 0730, switch to 4He target.
- follow procedures to restore beam
- check DC occupancy at 60 nA
- check beam blocker calibration
- take data at 60 nA
- take data until end of run
DAQ configurationPROD67_noVTPread , production trigger rgm_6GeV_inb_v1_0.trg At the end of each run, follow the STANDARD DAQ RESTART SEQUENCE
Announcements
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.
References and Standards:(last update 12/06/2021- 23:20) Nominal Beam Positions
FSD Thresholds
Reference Harp Scans for Beam on Faraday Cup: 2C24 (tagger harp) [1], 2H01 [2] Reference Harp Scans for Beam on Tagger dump: 2C21 [3], 2C24 (tagger harp) [4] Reference Monitoring Histograms (80 nA, production Ca-48) [5] Counter rates
Beamline vacuum: should be not higher than 5e-5.

General Instructions:
Note that the dome lights when switched off cannot be turned back on immediately because they require 10-15 min to cool down.
