[Halla_running] [Revised Logentry] RC daily update

Logentry Text:

Not much to report since yesterday evening (https://logbooks.jlab.org/entry/3609962): This morning, Jessie has discussed the plan to go forward with engineering and facilities after the 8am meeting.
There are some safety and administrative procedures to perform before actually starting the work (e.g. reduce risk of ODH in the work area for the former, RWP for the latter).
Engineering will produce a new O ring with viton instead of regular rubber to replace the defective O ring (that itself shouldn't take long).
Note: I have said before that the O ring was *presumably* leaking because radiation damage, but this is not certain. It will need to be taken apart and examined before drawing any definitive conclusions.
