RC summary, Oct 19 - 20
(we are taking data and need more shift workers ;)

I took the RC phone from Tyler Hague after the 1:30pm MCC meeting.  Thanks Tyler for his great job!

Hall was open in the morning for visitors. Work in the hall:

SHMS preshower channel 13 moved to a new HV channel:  https://logbooks.jlab.org/entry/4063287
target loop 2 fan readback fixed: https://logbooks.jlab.org/entry/4062317
SHMS aerogel turned off:  https://logbooks.jlab.org/entry/4063605

We went to beam permit around 1:30pm and wait for the machine to come up.
We dropped to control access for a short time around 2:30pm, Jixie and Xinzhan went in and replaced a gas bottle for the SoLID GEM test. They will need make another entrance next week.

Around 5:30pm, BCM05 (UNSER) temperature started to fluctuated (from 110 to 130 degree) https://logbooks.jlab.org/entry/4063493, MCC called EES expert to come in. The control card in counting house was replaced (https://logbooks.jlab.org/entry/4063553) and UNSER went back to the set temperature at 11pm (https://logbooks.jlab.org/entry/4063610)

We started to get CW beam around 11pm, and continued data taking at setting 1 (HMS at 20 degree for EMC, SHMS at 8 degree for SRC) with Fe, Ag, Th targets. The beam was trippy at 60 uA now and then, brought this up in the morning MCC meeting.

We will have our daily RC meeting at 11am today to discuss regular topics plus the runplan adjustment and date for target ladder change.
