1. Beam Update
2. Production Run Update
   1. List of good runs is on the analysis shift page. Calibration can start for some subdetectors.
   2. Discussed the current progress regarding the run spreadsheet and the data quality spreadsheet
   3. Need to have a summary slides of the important plots to monitor for the data quality spreadsheet
3. Physics on ρ^{0 channel of Run 90059}
4. Trigger Discussion
   1. 2 Triggers:
   2. FCAl and BCAL minimum ionizing (1)
   3. Start counter
   4. Will kill some physics, primakov production, excited nucleon or recoil on coherent only neutrals (2) in final state
   5. To account for this, add trigger with larger energy threshold to accept primakov style events
   6. Completelmentary, has larger energy deposition
   7. Primakov is z^2 hunting for small enhancement bumble in angle dis. Or eta, would be big peak with carbons.
      1. larger eta mass than pion
      2. larger the target the better, enhancement for primakov
      3. pi0 in hall b (primakov in carbon)
      4. more physics, sensitive to this
      5. 50 kHz with 90% live time
   8. Adding TPOL yesterday
      1. will use it somewhere eventually
   9. Ahead of schedule
      1. already have production data on he 4
      2. Took AMO that can used in
   10. For Flux,
       1. tagger and PS needs to be calibrated
       2. estimate is total number of PS triggers
       3. integral of PS spectrum
   11. Insert calorimeter into beam, count photons. In parallel, run PS, so you know acceptance, convulsion of PS converter (thickness and sigma) acceptance

1. Radiator
2. Timing Cuts
3. Bo and Phoebe's input from the spreadsheets
4. Possible take a look over the run files that we have, if they get ready
