T9/PS run Daily Briefings - 3PM

 
Daily briefing minutes

August 9 - 32-1-A24

 Communications

No beam since this morning at 9. CUrrent estimation is NO beam before tomorrow afternoon, shifts are suspended, we will restart tomorrow at 12 and update. 
Tagger calibration done. 2.5 GeV e beam used to collect 100K tagged gammas, 2M events full-brem gammas

 Online&DAQ Report

DAQ sync with AD ran smoothly since this morning at rates up to 1500 part/cycle, corresponsind to a peak rate of 1KHz (max is 2K), with a beam intensity of 60KHz

 OfflineReport

- Latency for full-brem runs is large due to caltuple merge, Luca to investigate with Francesco if pipeline can be coinfigured to link to merit and SVAC tuples before merging caltuple; the other option is to give up the CAL tuple (to be discussed with CAL people)
Offline monitor report (Claudia) - must transfer correct geometry in AD recon and check filling of si det of downstream tagger

Tagger calibration onnline report (Carmelo) - all is under control
Preliminary analysis of 1 full-brem run (Eduardo, Benoit)

 Program

- agreed program here

Notes 


August 8 - 13-3-005

 Communications

  Beam back from9. Standard beam with 3 spills from 11. Discovered that magnet settings were wrong and gave beam crossing cerenkov detectors therefore reducing e fraction and trigger efficiency. After loading the magnet settings file from Erik everything was fine and we could restart.
Tagger calibration program going on; usptream arm aligned with CU, BL scan in progress, dowstream arm to be aligned by tonight.

 Online&DAQ Report

DAQ sync with AD ran smoothly since this morning at rates up to 1500 part/cycle, corresponsind to a peak rate of 1KHz (max is 2K), with a beam intensity of 60KHz

 OfflineReport

- Francesco: new pipeline processing runs from 1151
-  Offline coordination

 Progrm

- CU DAQ max readout rate test with random generated pulses
- DAQ sync w/o external 3ms veto
- no beam foreseen for the night, restart shifts from tomorrow morning 8AM 

  Local Offline coordination  and daily reports: Claudia for TKR, Philippe for CAL, Eric C for ACD, Nicola M for ancillary and beam diagnostics

 Program

- Finish tagger calibration by tonight
- Collect 100K in tagging mode, CU at 0 angle, center of tower 2
-  Collect 2.4M evts in full-brem, CU at 0 angle, center of tower 2

   When changes to the beam line are to be made, please use the table provided here and not the table from EBCR

 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
