Please find a detailed report for the past 24h data-taking of July 13th: RC
summary https://logbooks.jlab.org/entry/4417767
- We had a in general smooth day for physics data taking. In addition to
regular known issues with DAQ reboot and upset ROC, ATOF HV, we encountered
2 times of the TORUS alarm and magnet ramp down at noon 12:20pm and in the
afternoon 4:20 pm. Experts ramped up the torus shortly after it, and it
were diagnosed to be a Cryo communication issue. The Cryo expert plan to
look on it today. ECAL sector U1 13-36 were tripped during owl shift,
therefore, a HV board replace will be scheduled today afternoon during the
target purge.
Our plan is to continue the physics run on 4He + 325nA for the following
days.
Best,
Zhiwan
