H4/SPS Daily meetings
September 6
First day of beam. We were supposed to have the beam at midnight, we got it at 3PM. The timing was looked at, the calorimeter signal is now coming earlier with respect to the tracker as compared to PS. BT 5 configutation with cal/tkr in the middle of the trigger window at SPS is now the baseline.The calibration of the calorimeter (cross pattern) at 100 GeV was started then interrupted to let the experts optimize the beam tuning at the highest energies.
Program: completion of the 100 GeV calibration runs, ACD calibration with protrons+pions, switch to 200 GeV, scanning of different (X,Y, theta) configurations
T9/PS run Daily Briefings - 3PM
...
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
