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 will call MCC to turn the beam OFF to 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 and the RC and JLab medical services immediately to arrange replacements.
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.
Tomorrow (Thursday) accel crews will be setting the beam for Hall A we will go to controlled access, and bring magnets down (The Torus ramp down will take about 1 hour.) for cryo tuning and walkthroughs. Short term schedule [1]
Run Plan for the Weekend (April 13 and 14)Take production data! Don't break anything! Keep an eye on the backgrounds, for example as seen in the downstream halo counters (e.g. scaler_cS10b, currently ~3-5 kHz @85 nA for C+D targets), and on the 2C24 and 2H01 BPM positions. Both of these give confidence that the beam remains centered on the RGE target.
Production data taking
In case of the need to manipulate the whole target system - cryotarget or solids - please contact the target experts. LD2+C runs

ReferencesBPM 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.
