Back to Run Coordination Meetings:Fall2022


Friday Dec. 2nd

Last 24h

  • Thursday was spent mostly with production on full target. It was an efficient day, with 17.8h of ABU (7am-7am).
  • A. Somov did a low beam current test of the Active Colim. high gain in anticipation of a future TAC run. It looks good.
  • Hall C was supposed to get back to running in mid-swing shift, which would be followed by us doing Harp scans (last ones done: Oct. 21st), but it did not happen (Hall C vacuum issue).

Reports

Issues

  • The FDC fadc installed Wednesday by Naomi and Lubomir needs baseline calibration (Sergei, when we have ~20min of beam. No access needed).
  • cdc p_diff alarms

Short term run plan

  • Hall C is expected to be back to running ??any time??.
  • Harp scan after Hall C beam is tuned (last harps done on Nov. 21st, but Transmission is fine.)
  • FDC fadc:
    • baseline calibration (Sergey, opportunistic during a 20min down time).
    • 20 min Row mode run (either with beam or cosmic). Beni will analyse it and determine if the fadc needs to be replaced
  • If beam is off, we have opportunistic work:
    • Beam off for more than 1h: rapid access for A. Somov and Vlad for ??
    • Beam off for more than 2h: rapid access for Lubomir or Beni IF FDC fadc needs to be changed
    • Beam off for more than 2h and RadCon is available, need to survey fadc to removed them from the Hall (Lubomir/Codi)

Tentative longer term run plan

  • TAC run
  • Luminosity study

Thursday Dec. 1st

Last 24h

Reports

Issues

  • The new FDC fadc is worst than the one replaced (Naomi/Lubomir). The problem is only for raw mode run.
  • Many cdc p_diff alarms (e.g. 0.8 alarm/hour during swing and owl shifts) leading to runs often shorter than 2h (this has already been discussed several time. This is just a report).

Run plan

  • Hall C is expected to be back to running during swing shift today.
  • 20 min test at low beam current/high Active Colim. gain to see if adjustment are needed (A. Somov)?
  • Last harp scan was done on Nov. 21st. Should we do a new one? (Transmission is fine.)
  • Luminosity study?
