Program: Specific studies for the "baseline restoration" (aka "pedestal drift") problem using LATTE's muti-engine capabilities (configuration files provided by Jim Panetta). CAL pedestals, internal trigger runs. Switch to 50 GeV.
Analysis: A look at the deposited-energy distributions measured in the different CAL layers
September 8
Status: Smooth operation most of the time. Program of different geometrical configurations completed at 280 GeV. FHE tests completed at 280 GeV (theshold=0.5 GeV-2 GeV) at 2 different positions. Cerenkov counters have been checked (there was connection problems), and are now working, although the efficiency is low.

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
