Yesterday, beam came back around 20:30 pm. A harp scan was performed (IHA3H07A: https://logbooks.jlab.org/entry/4277726, IHA3H07B: https://logbooks.jlab.org/entry/4277730). Production run on LD2 target was taken overnight until 8:30 am this morning. The ABU is 6.7 hours for the past 3 shifts. 

Today, MCC is going to to complete the Hall A pass 2 setup and send beam to Hall A dump. There won't be beam during this work. Since currently there is a large intersection between A beam and B/C beam that needs to be resolved, the MCC work would probably take more than the scheduled time. We plan to use this downtime to change the HMS polarity for the upcoming positron runs. And Hall C will be in controlled access soon (around 9:30 am). Josh and the technicians plan to investigate more on one NPS chiller that has frequent low water alarms (https://logbooks.jlab.org/entry/4277639).

Currently, the earliest time that Hall A plans to close the hall and requests beam would be at the end of Friday day shift. 

The RC meeting is at 11 am
