We ran production yesterday. The average efficiency of yesterday's day and swing shifts is ~50%. During today's owl shift, we only got 2-h production data, which was due to RSEP9 trip (2.5h) and 0L04 dropped out of high voltage (3h). The beam was back around 9:00 this morning, after the standard procedure of checking the spot size (https://logbooks.jlab.org/entry/3843812), raster, C-hole (https://logbooks.jlab.org/entry/3843826), and Compton rate (https://logbooks.jlab.org/entry/3843853), we went back to production at 10:43 am.

Plan is to continue production.

 Scheduled down time
1) There will be a 4-hour beam study at the beginning of this swing shift, which was scheduled from 16:30 to 20:30. Hall A will be under beam permit during the beam study. 

We will have our usual meeting at 3:30 PM today. Bluejeans link: https://bluejeans.com/256205934
