- Updated shift list ....
- UPS ....
July 29 8PM - T9 barrack

1) Ric: CU DAQ PCs restarted ok, need to switch on CU and acquire some test runs to verify DAQ hardware is ok
2) Philippe: verify XY table is working fine, initialize again to establish reference point
3) Fabio: AD DAQ is on again, test runs being taken and look ok
- List of tasks for 7/30 (no beam available)
- Online team + Sandro: provide online plots for tagger alignment and calibration
- Francesco: verify pipeline is fine and test ACD reconstruction on local PCs, test also ANC reconstruction, improvements on MC geometry in progress, measurements of beamline
- Claudia/Monica: verify offline monitor
- Eduardo: provide list of interesting runs taken so far and distribute it to analize
- Luca, Gloria: provide UPS for at least LAT-BTserver, enquiry about UPS for other DAQ machines and CU PS
- Luca, Gloria, Nicola, Eduardo: provide sketch of experimental setup, trigger setup
- Luca: new shift list with 8 hour shift and 3 people per shift (4 if possible)
July 29 - T9 barrack

- POWER OUTAGE ON THE WHOLE CERN SITE SINCE 8AM - NO ESTIMATION ON POWER AND BEAM. After contacting the control room we decide to stop shifts until the power is back, and we meet at 8PM at T9 to check again with CR; if no changes happen we will meet again tomorrow at 8AM.
- Procedures for power back: even if chiller is not operational there are no issues with CU as gas is flowing and ambient temperature is below 30C. No danger for the CU when power comes back, just have to properly reset XY table before operaing. Experts will have to work on restart DAQs and network connection as soon as power comes back.
- First tagger arm aligned with beam, chambers orientation understood; 1 finger counter working, the other being fixed. Current scintillators installed are S0 (10x10), S1(finger), Sh (halo veto), S3 (10x10 before CU)

Online&DAQ Report
|
- The external trigger signal delivered to the CU had a wrong TTL polarity, resulting in the CU being triggered on the falling edge of the trigger occuring 800ns later than the rising edge; this was corrected and the external trigger signal was aligned with trigger requests from TKR and CAL. New test of DAQ sync will have to be performed to verify if we can work at higher rate (200 evts/spill was the max stable rate tested so far)
- Owl shift: all ACD tiles hit by the beam (5 GeV pione) and MIP peaks aligned
- absence of CAL-HI trigger understood: bug in configuration file disabled CAL-HI, now cured and good FHE file loaded; CAL HI triggers seen in the data
- CU: Ric investigating phasing errors |
Offline Report
|
Francesco:
- recon runs resubmitted, few runs still fail at different pipeline stages
(@ digi for corrupted events?; @recon for G4 stuck; @svac to be investigated)
- new BTRelease installed on local PCs
Claudia:
- latest fixes to offline monitor, waiting to test with last night data as soon as power is back
|
Program |
- Carmelo and Sandro working on the online monitor to align and calibrate the tagger
- define trigger configurations
- CAL runs with e
- Tagger calibration
- provide instruction for shifters to post on confluence (CU DAQ, AD DAQ, trigger setup, offline distributions to monitor) and in the barrack
|
Notes |
- people are invited to start looking at data offline and report
- from monday will have 30hour for the daily reports and 30min for offline report
|
July 28 - room 13-3-005
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
