Summary of past 24h:

Shifters summary:

Day: https://logbooks.jlab.org/entry/3826354
Swing: https://logbooks.jlab.org/entry/3826767
Owl: https://logbooks.jlab.org/entry/3826936

• Annoying Torus alarm issue solved
• Eric C. and the remote shifter (I guess it was Susan B.) noted a ' hot' sector in the RTPC

• • Jiwan P. solved rebooting mvtX crate.
• RTPC tripped a couple of times (not very often), but apparently, in one occasion was difficult to recover, requesting beam off. Again, Jiwan P. solved and the beam was restored increasing current in small steps. According to Jiwan P. logbook entry, is possible that there is not complete instructions of how to proper reboot the RTPC (I have to check it, I was sure that it was written in March).
• Another 240nA test during the night.
• beam instability reported for 20 min during owl shift.
• Yuri G. showed me that the light in the hall was ON when it was supposed to be off. We will take a fast entry to the hall to turn it off in an opportunistic window. EDIT: Bob M. said that light should be ON.
• Due to a unexpected beam down (under the title "Rf/Magnets mysterious trip"), Jiwan P. called to check if we should purge the target or change to another gas as was mentioned in previous meetings. After consulting Sebastian K. we will change to Hydrogen.
