Summary

Yesterday (02/28) was the Maintenance Day during the Day shift (https://logbooks.jlab.org/entry/4258304) and during Swing accelerator did some beam studies (https://logbooks.jlab.org/entry/4258458). The beam was restored to the Halls late Swing and we proceeded back to production. We took Dummy runs and then switched to LD2 for the night. Hall B performed the Moller measurements at the end of the Swing shift and then changed IHWP from OUT to IN, after which we ran the flipper script.

We are currently at KinC_x36_6 (NPS Calorimeter at 6.0 m) and going to stay at this kinematics for the next few days. Data taking was smooth overnight without major issues.

Planned Access to the Hall

Julie wants to make an access around noon to repair two NPS channels.

Current Run Plan

• Short-term run plan: https://hallcweb.jlab.org/wiki/index.php/Short_Term_Run-Plan
  • KinC_x36_6, NPS at 7.5 deg, calorimeter at 6m

• NPS position for the next kinematics setting:
  • 5m vs 6m: https://logbooks.jlab.org/entry/4258150

Current Issues

• Hanjie was concerned that some NPS crates have relatively higher fan temperatures (~95F). We put box fans for those crates. We also asked Facilities if they can lower the AC set point from 68F to 65F (was done yesterday).

Future plans

• Monday (08/04): Sweeper wings off (Walter).
• Monday (08/04): Spectrometer rotations: To be done after taking the Wings off. HMS-SHMS separation needs to be certified in the hall (Steve L).
• Moller measurement next week (?)
