  News from PS/PS Users Meeting:
-intervention on QED2 scheduled to end 5PM; spare was found to be not working, a second spare was available but needs to be equipped with a new vacuum chamber that will be taken from the 1st non good spare
- beam loss in the separation magnet between east hall south and north branch; currently this is the reason why we have no beam; if replacement of QED2 cures the loss we should get beam back tonight, otherwise a technical intervention will be required, and cooling time is 4 days minimum (currently the radiation level at the separation magnet is 2mSv)
- supercycle changes: agreed changes for next week so that we get 3 spills in east hall during working hours and 4 during night and week-ends; the fourth spill will come around 4 sec later that the first three. new changes wil be discussed for week 34 (check weekly schedule here)
- Luca to investigate on the possibilty of an extension with the MICE group which is supposed to run after GLAST 

 Online&DAQ Report

Ric confirms that agreed modifications on spill structure for next week will not hamper DAQ sync and data merge online

 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
