Program: Completion of 20 GeV program. Switch to 10 GeV for the night. Swith 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).
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 |

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 |
