-philippe (CAL): completed analysis of yesterday on energy resolution, results are confirmed on all the tagged photon runs; at 0 and 30 degress the parametric method has a significant bias, and the resolution is worse than MC. The likelihood method show smaller bias, therefore a systematic error from the tagger can be excluded. Require confirmation of the beam energy spread and tagger resoultion by tagger people
-berrie: pion contamination in photon data, from pile-up and cerenkov inefficinecy; photons conversion efficiency in the TKR show how layer 15 has a reduced number of vertices wrt to MC (pdf)
-Carmelo: layer 15 is known to have large number of bad strips, and looking back at e runs we realized that the spot we are hitting with photons at the center of tower 2 is actually a dead area ( 1 and 2); hard to see with photons but clear with electrons (and from old pisa data):
-eric (ACD): analysis of last night runs with photons at 145 degrees show some activity in tile 4, but the spectrum seems compatible with a beam halo; more investigation going on to correlate with info from tkr and cal

 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
