Program: Different electronic configurations to investigate the FIFO full issue. Switch to 20 GeV (10 GeV?) protons.
Analysis: Luis has presented the first comparison between MC and data for the ACD distributions. The agreement seems reasonable.
September 10
Status: Smooth operation most of the time. Program of different geometrical configurations completed at 50 GeV, well along at 20 GeV. Runs with different trigger engines (internal trigger for physical events: 1 range readout, 0-suppress, external trigger for random events: 4 range readout, non 0-suppress) performed successfully to study the pedestal drift issue.

Communications | - Magnet failure: MNP17 colling system failure at 1AM stopped data taking for several hours but no damage on hardware. Physics restarted after 2 hours w/o silicon tagger for CAL calibrations. Magnet repaired in the morning
- CU cooling system changes: CU/ISC cooling coil in the ISC base plate leaked: it was emptied and is now non available, we will rely on top cooling coil as no intervention is possible; the chiller was moved closer to the ISC to minimize thermalization of coolant with ambient through thermal exchange with the zone air, now chiller more efficient; fan added to cool XY table motors. Please look at the temperature during your shift |
Online Report
| - DAQ sync studies going on
- CU: Ric investigating phasing errors |
Offline Report
| Francesco:
- pipeline nicely running
- 1st 1000 evetns in SVAC ntuple duplicated
Claudia:
- offline monitor requires script to parse rcReport info and link to MC files (Navid working on that)
- MC and CU cooprdinate systems mismatch (check with Philippe)
Dave:
- no CAL-HI triggers in last night data as fhe values were saturated
|
Program | - Complete DAQ sync studies
- perform CU timing studies to optimize TACK (timing/script vs ext trigger manual delay)
- explore beam conditions
- ACD calibrations (ideally 5gev p, if NA 5gev e)
- CAL runs with e (Benoit)
- Tagger calibration start on 29 morning |
Notes | - Fill elogbook
- Take your shifts and launch runs yourself
