    • Sasha completed PS trigger studies
    • 6 hopefully good production runs
    • Lost beam for half of swing w He fault in accelerator; less stable during owl & then off for 2h for cryo module failure
    • Length of run -> 300M & 150M (<2h for calibrations, daq is running much better than previously, full cycle of 5 runs takes too long)
  2. CEBAF:
  3. Action Items:
    • Microscope occupancy is off - should be fixed when Richard has loaded new thresholds
  4. Issues:
  5. Reports:
    • Monitoring
  6. Run Plan:
    • Week 2 Week 3 Week 4
    • TAC run prep on Thursday
      • 0930 Quick access for Hovanes with ARM to install the Pb converter; also remember to call Melvin from radcon to fix the alarm (number on whiteboard & alarm)
      • Hovanes will calibrate A.C. high gain setting on Thurs am.
    • TAC run on Friday
      • Hall C will be down from 7am for 6-8h
      • MCC need ~2h to set up low current, ETA 0830-0900, setup DAQ (~1h, Sasha), take data for 4-5h. (Go to 30nA & V-wire if we run out of single-hall time).

  1. Notes from the previous 24 hours:
    • *There is NO RF recovery time scheduled for today (Tues) - cancelled ~3.30pm Mon *
    • Day + part of swing shift: Mike McCaughan & Todd retuned Hall D beamline. Beam profile looks way better and rates are back to normal. am pm
    • Swing Richard gathered TAGM threshold scan data. Still needs to calculate & then set new thresholds.
    • Owl production 3 hopefully good production runs at 450nA (to match daq rate). New amo reference. Beam position started wobbling after 5am but not too bad.
  2. CEBAF:
  3. Action Items:
    • Microscope occupancy is off - should be fixed when Richard has loaded new thresholds
  4. Issues:
  5. Reports:
  6. Run Plan:
    • Weekly schedule
    • Richard (tagm), Sasha (PS). Outstanding: rate comparison (8h) & high rate studies (4h)
    • TAC run on Friday
      • Friday is good for Todd and Hall C (they will be off from 7am for 6-8h)
      • We will need access to install Pb converter, & then time to calibrate A.C. high gain setting (do this on Thurs morning with ARM, 09:30 is good with radcon)
      • Radcon would like to swap a part in the overactive alarm while the hall is down, will take 5 mins, we need to phone the number on the alarm box to call them in (not the survey team)
      • MCC need ~2h to set up low current, setup DAQ (~1h, Sasha), take data for 4-5h. (Go to 30nA & V-wire if we run out of single-hall time).

  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
