Summary

Yesterday 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.

  • 5m vs 6m: https://logbooks.jlab.org/entry/4258150

Current Issues

• NPS crate temperatures

Future plans

• Monday (08/04): Sweeper wings off (Walter).
