Program: completion of the 100 GeV calibration runs, ACD calibration with protrons+pions, switch to 200 GeV, scanning of different (X,Y, theta) configurations
September 7
Status: The beam is now much more stable. Calorimeter calibration completed, ACD calibration completed, scanning of 200 GeV configurations almost completed. Some runs were repeated after it was found that 4 scintillators used for the beam tuning were still in and be moved out. The pressure in the 2 Cerenkovs (1.2 bars so far) was set to 0. The dependence of the calorimeter measured energy as a function of rate has been investigated ("baseline restoration" problem). The effect is clearly visible. We decide to limit the rate to 400 Hz.
Program: switch to 280 GeVand repeat same configurations. Specific BT configuration files

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 |
