  1. 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
  2. CEBAF:
    • Expect 2h downtime from 9am for HA to go to 2 pass; MCC will work on our optics during that time
  3. Action Items:
    • Update reference plots (CDC's new ref colz scale is off)
  4. 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
  5. Reports:
  6. 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
