[Hallc_running] [New Logentry] RC Daily Update

Accelerator status:
- no beam at the moment due to problem with vertical separator, but RF expert looking into it.
- found the cause of and resolved beam instability issues (high beam trip rate issue), so lower beam trips are expected once beam is restored
- from this morning RC/PD meeting:  BPM dispersion in C-line is measuring 1 mm PD would like to have the crew chief nudge the 
dipole closer to zero once beam is restored

Experiment status:
Since yesterday, the shift crew has completed the first two production sub-settings (SHMS Right Center) for pionLT
Currently waiting for recovery of beam to proceed to taking 'SHMS Left' setting.

We'll have brief RC meeting today (more like analysis meeting), to discuss various issues brought up by Jacob and try to make sense out of them.

The analysis concerns are: 
1) lower coin. rates than expected:  https://logbooks.jlab.org/entry/4004609#comment-38500
2) epsilon angles mismatch:  https://logbooks.jlab.org/entry/4004615
