UPS identified and ordered (3 UPS with 900W x 7min for DAQ PCs, 1 UPS with 450W x 7 min for 28V PS); should be delivered wednesday

 Online&DAQ Report

CU DAQ maximum readout rate with full error parsing in the code is 300Hz average, corresponding to 4KHz instantenous rate during the spill (our spill structure is 3 x 0.4s spills every 16 s). Indeed runs were taken with instantenous rates up to 2KHz. This max value will be checked with a random trigger generator (low threshold scintillator) and with the beam as soon as it gets back.
 Ric on TEM errors: come in a variety (TKR fifo full, phasing errors, parity errors ...); some are just fake errors connected to the so-called TEM-bug in the CU TEM (which are not flight). TKR fifo full errors probably connected to beam conditions producing showers in the last si det upstream the beam and before the CU (see also offline reports), in any case the almost full flags in the GTCC buffer was changed to 0X3E from 0x32 (from E Siskind) to allow for more hits in the tracker before back-pressure events and slow readout rate. Phasing errors found in 1 run only so far, so might be connected to wrong settings - a run with beam shooting across towers should be taken to check if phase errors appear in such conditions. In summary, if we keep trigger rate below 300Hz average we should run w/o errors and be limited by the AD DAQ deadtime (approx 1 ms)
DAQ sync: tested with external veto set to 3ms, which was set to avoid CU errors in the wrong assumption that the CU DAQ readout rate is limited to 300Hz instantaneous and not average ; need to retest it w/o such limitation and with the only veto given by the AD DAQ

 OfflineReport

- Francesco: acdrecon and adrecon in new BTRelease; bug fix in the svac ntuple to avoid overwriting first 1000 evts 
- Benoit reported on an anomalous high number of hits in run 811, but also in another run for which the si det al frame was not in the beam
- Philippe reported on a strange effect in the distribution of the transverse dimension of showers in the CAL for most e runs taken for CAL calibration (700-750), indicating 2 classes of events; he also reported on a raw energy distribution with 1% of the events exceeding the beam energy
- Claudia spotted an anomalous high number of tracks in the runs (700-724)
- Discussion: the above analysis and the online picture of the beam on the last si det indicate that the beam line is too congested and must be cleaned; the si det will be repositioned to remove the frame from the beam, and a subset of scintillators will be used for trigger (S3 will be removed, and after the beam is well understood we might rely on Sh in anticoincidence with S2 

 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 

Notes 

Action items
- Luca: provide shift task list, revise shift log and transfer paper logbook info in there for reference for everyone
- online: add an all-particle type selection in the DAQ GUI
- carmelo and eduardo: verify ACD mapping, ROI definition and ACD timing 

 Communications

 - 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

 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
