T9/PS run Daily Briefings - 3PM

 
Daily briefing minutes

August 17 - 13-3-005

 Communications

- news from PS/SPS users meeting: the MICE experiment will not run after us, so we have a chance for an extension; the coordinators feel this is not necessary and hard to support; the maximum we can afford is to extend 1 day if really needed; on the other hand we need to organize for the transportation of our equipment to SPS, currently scheduled for wednesday 23; Luca to contact Ilias and discuss possibility of move on thursday if we are late with the program after the weekend
- next week cycle structure will change and will extend to 22s; possibility of 8 spill maximum on our beam line, excellent support from PS; on our side we need to make sure the spill gate from the ancillary follow this change (Monica B to check, should be fine as spill signal comes from accelerator)
- very low beam rate after this morning intervention, control room solicited to solve the problem, now working on that
- Luca working on schedule to fit all requested runs, detailed plan to come but feeling is that all will fit
- Erik provided 1 10x3x1cm counter for the e+ runs; Bari provided 2 1x1x0.2cm finger counters for the same purpose. 

Online&DAQ Report


 OfflineReport

- full-brem data on twr3 show standard distribution of vertices (no dead areas)
- ToT preliminary analysis (Francesco)

 Program

- p program completed
- full-brem and tagged gamma at 2.5 on twr3 completed
- started e scan at 5gev, then go back to photons 

 Notes 


 

August 16 - 13-3-005

 Communications

- 1 PMT on the twr3 side top tile seems to be badly connected (very low PH) after the top tile was repositioned in its original location after albedo runs - might try fidgeting with the light guide to reestablish connection
- Lat-btserver crashed last night when opening a pdf file from confluence (Luca L). Lat-btserver has problems with windows manager, so please do not use it for open files that are not strictly connected to the DAQ. THe Monitor PCs now have a firefox link on the desktop that you can use to connect to the web (Johan).
Restart of btserver was fast,  but 2 mistakes affeted data until this morning:
- housekeeping was not turned ON, and only restarted this morning; data logger shows anyway normal values for T and rH
- ACD HV was not turned ON and only re-enabled today at 2PM; please alway look at ACD histograms in the online (even if they were supposed to be empty with a 90 degress beam....)
- Socket Gleam is alive! actually helped immediately with the issue of ACD HV because we saw reconstructed tracks pointing to the ACD tiles and saw not hits in the ACD distributions, so went to the HV control and found it to be off

 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
