- Benoit on CAL pedestal drift: analysed rate effect in CAL crystal on pedestal for p runs; there is a clear effect that shows a broadening of the landau peak in CalEneSum at high rate; cutting on GemDeltaEvtTime and selecting particles at the beginning of the spill the Landau appear normal. The same is confirmed when analyzing few runs taken with lower p rate. Positron and electron runs seem unaffected. Michael looking at tkr data to seek for any rate effect; the idea is to monitor the efficiency of a FE vs GemDeltaEvtTIme, as no runs with different rates are available for p through the tkr.
- Stefan on e+ MC; proposed setup simulated with 2 target, MMS and 1cm Al; fiducial cut on veto identified; simulated about 90K e+ and e- hiting the annihilator. Found too large differnece between e+ and e- before cut on fiducial volume, need to look into that. With cut on fiducial volume the brem background is better for MMS. Nb of simulated annihilation events is 25 out og 90K (similar to the events found by Philippe after his cuts to identify tracks pointing to the target)

 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
