- 1st positron annihilation program completed overnight; shooted 1M  e+ and 1M e- through MMS placed in front of ACD tiles; CU oriented at small angle to increase path length in tracker and benefit from good tracking to point tracks to MMS target. Analysis will rely on ACD efficiency to reject e+. Target placement done using a pb brick to shadow the beam and then replacing the brick with the MMS target
- switched to p this morning; MMS target placed between the beam and the CU, shooting beam in 2 positions: small angle through twr3 towards twr2, 90 degrees entering twr3; will collect 10M p for each position at 10 and 6 gev; program will go on until tomorrow

 Online&DAQ Report
nothing to report

working well at very high rate with p since this morning, 4KHz peak rate. Some errors appear but are known and under control (mainly FIFO full and parsing errors)

 OfflineReport

postponed to VRVS later; will have contributions on PSF (Claudia), E recon (Philippe), ACD cuts and positron runs (Philippe,Eric)

 Program

see above

 Notes 

new shift list until the end available on confluence; reduced to 2 people/shift to better support analysis now that running is stable 
meet at 6PM in this meeting room for VRVS together

 - 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
