10.23-10.24 summary: 

On Sunday we continued data taking at setting 3. Everything went smoothly until 9:40pm when our HMS Q1 interlocked and wouldn't reset. Called magnet on call (Joe) and MCC for hall access. Joe quickly came in and tried to diagnose the issue from the counting house while waiting for ARM. The magnet tripped a few more times before we finally brought it back without a hall acess, during which ARM arrived and nicely agreed to stay with us to make sure the magnet would come up. See summary and note from Joe at https://logbooks.jlab.org/entry/4067179

We returned to data taking around 11pm. Beam was down from ~2am-7am due to the north LINAC LCW aperture water flow fault. https://logbooks.jlab.org/entry/4067383
Now beam is back, we are running at 60uA and Hall A also needs high current.  MCC will monitor the beam stability and have dedicated discussions. 

The SHMS CODA crashed very frequently since the beginning of this experiment because CODA 2.6 can not handle high rate very well. To reduce the beam time loss on restarting CODA, we updated our shift worker instruction from ending a run with 2 million events to 4 million event as suggested by Bob. https://logbooks.jlab.org/entry/4066486

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