Program: Completion of 20 GeV program. Dedicated runs near cracks at 200 GeV. Switch to protons+pions tomorrow morning, when the experts are around.
Analysis: Preliminary results of the "pedestal-drift" runs (Benoit). The expected effect is clearly visible, but needs to be investigated in more details.
September 9
Status: Smooth operation most of the time, but for a long interruption from 4:30 to 9 AM. Program of different geometrical configurations completed at 100 GeV. Specific configurations proposed by Leon (45 deg, with particles entering the tracker sideways within the thick-converter layers) were used as well.

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
