Logentry Text:
We reached our statistical goal for the SHMS 10 deg configuration and moved to the SHMS 7.5 deg setting at around 10:00 pm yesterday. There was a brief period when the raster GUI was frozen with a white alarm (which probably means no communication) while it was still ON. MCC rebooted the IOC that fixed this issue (https://logbooks.jlab.org/entry/4035449). Shifters should keep an eye on the COIN time from the first full replay after a configuration change to make sure that we aren't taking too many randoms and are at an optimized beam current (example: https://logbooks.jlab.org/entry/4035519). We have a couple of things planned for the maintenance day tomorrow:

Beam will be turned OFF at 8:00 am.
RadCon full survey requested —> Adam Hartberger 
Walter + tech —> Pumping on the HMS transfer line
Dave Gaskell —> Survey of electronics
Bob Michaels —> ROC4 fan/temp checkout
Beam will be turned back ON at the start of swing shift.
Please let me know if you would like me to coordinate anything else.

The updated plan for the next few days (https://logbooks.jlab.org/entry/4035552):

1. LD- Q2=1.60, W=3.08 THshms=7.50 -- Aug 30 Owl through Aug 31 swing + time lost due to accelerator maintenance (8-16 hours?)

2. Lumi scans and Heep-singles -- 3 shifts on Sept 1, but the completion is actually sometime on Sept 2, depending on how long it took to recover from maintenance (usually about a shift of recovery after a shift of down)

3. LD- Q2=1.60 W=3.08 THshms=6.00 -- Supervised remote rotation probably early morning on Sept 2.  Continue data taking until beam off a week later.
Let's have a brief RC meeting today at 11:00 AM EST.
