Important Notes
- In case of medical or fire emergency, call 911 or 9-911 from a LANDLINE phone in the Counting House and inform the Crew Chief and RC.
- In case of evacuation of the Counting Room (e.g., due to a fire alarm), grab the shift expert phone and leave the room through the "EXIT" door leading to the parking lot. Do not leave through the hallway! Call the RC once outside so the latter can call MCC to turn the beam OFF for Hall B and inform other Hall B staff members.
- If you have symptoms or a positive COVID test, do NOT come to your shift. Instead, inform the PDL, the RC, and JLab medical services immediately to arrange replacements.
- In case of a problem with the HV Slow Controls, EPICS in general, please call the primary expert on-call: Nathan Baltzell, before reaching out to anyone else.
Please put all essential information on the main hall B log HBLOG. Some important alarms have been documented on HBRUN. Use the pulldown menu to choose where an error is reported.
Current Run Plan: May 8th to May 15th
Production data taking: LD2+Al runs
Previous Dual-target Configuration Plans- DC firmware test plan (LD2 + Pb)1) Take one run each with 1M events with the trigger files and beam current at 70 nA
2) Take one run with 500k events and beam current at 35nA with trigger file rge_inb_v1.0_200MeV_dcrb17_2.trg 3) Take one run with 500k events and beam current at 35nA with trigger file rge_inb_v1.0_200MeV_dcrb17_4.trg - Before the last run, call DC expert Florian so that he can change the firmware after the last run is finished. *** Note ***:
LD2+Pb runs
LD2+Sn runs

References- BPM PositionsThe most important BPMs to monitor are 2C24 and 2H01, from the point of view of assuring the beam remains centered on the RGE target. The values of the others can be influenced by other steering/focusing beamline elements.
- Harp Scans- FSD ThresholdsDo NOT change FSD settings without approval from RC or beamline expert!
- Charge Asymmetry- Upstream Halo countersIf the reading on the upstream halo counters exceeds 10, please contact MCC. |
