Oct 24-25

Very smooth data taking on Monday. There was a short beam interruption during Owl due to an injector issue (blown fuse) https://logbooks.jlab.org/entry/4068350

Early morning the SHMS DC1 HV tripped. Shift worker was able to bring it up after a few trials. https://logbooks.jlab.org/entry/4068409
This trip seems to correlate with the high rate at SHMS. For future reference,  we should run LH2 with <=50uA and LD2 <=30uA as long as SHMS is at 8 degree. https://logbooks.jlab.org/entry/4068405
The HMS Dipole NMR readback fluctuated in the past two hour https://logbooks.jlab.org/entry/4068509

MCC is planning a short RC recovery (~4hr)  on Thursday. The next RC can take that chance to coordinate a list of work including replacing SHMS angle camera, install SHMS Q1 vacuum gauge,  calibrate SHMS dipole LN2 valve,  and replace the GEM gas bottle.

There will be a daily RC meeting at 11am on the second floor of counting house.
