Revision as of 17:45, 29 September 2018

Notes from the previous 96 hours:
- Friday day shift MCC tuned Hall D beamline, improved convergence & reduced spot size
- Friday swing + owl Hovanes aligned the diamond for 45/135
- Saturday owl Collected 600M triggers of production data before one of the machine quads tripped at 5am. 3h down while it was replaced.
- Saturday day Beam returned long enough for Richard to collect data for TagM thresholds; then a RF module died & was replaced. Beam restored at ~ 1pm. Set TagM thresholds.
- Saturday swing MCC found an issue with the ion chamber calibration (2h).

Notes from the previous 24 hours:
- Beam position erratic throughout the day & first half of swing day swing
- Energy drift pathlength corrected
- Sergey completed first set of DAQ tests
- Stabilized mid-swing enough to attempt alignment but spot is huge 1.2 x 1.5mm
- Aligned 0/90, still need to do 45/135
- Collected 'production' data overnight, concerned about quality cobrems gui
- Whiteboard camera improved
- BOR records are back
CEBAF:
- Expect 2h downtime from 9am for HA to go to 2 pass; MCC will work on our optics during that time
Action Items:
- Update reference plots (CDC's new ref colz scale is off)
Issues:
- Beam
- Network problems
- Rootspy is often unable to find histos & make log entry, loses processes, need to start & stop monitoring w hdmongui.
  - Try start first. Open out the gui and count the # respawned processes, send info to David.
- Plot browser fix in progress
Reports:
- Monitoring Run 50698 (para)
Run Plan: Run plan
- Beam off at 9 for pass change
- Sasha PS (Sat, 1h) and Richard TAGM threshold not done yet
- Coordinate with C for TAC run - on or after Wed (otherwise need access), plan to install converter on Tuesday
- Acc whiteboard
- Counting house whiteboard
