T9/PS run Daily Briefings - 3PM

 
Daily briefing minutes

August 15 - 13-3-005

 Communications

- 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

 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 

meet at 6PM in this meeting room for VRVS together

-Photon runs: completed position 1(0degree),2(30degree),3(50degree) both full brem and tagged with primary beam at 0.5,1,2.5GeV. currently taking events for position 2 in tagged mode with 1.75 gev primary beam to fully populate spectrum.
- position 4 for albedo (145 degree): tile 4 moved from top to side of cal 3; full-brem taken, 1gev primary beam tagged mode as well, 0.5 gev was too slow this morning (only 3 spills); will need to move tile 4 back to its original location prior to positron runs
- discussion for following photon runs: philippe request tagged mode, more configurations; energy spectrum can be sampled in a coarse way to the benefit of more configurations, as e recon studies are more sensitive to gemoetry (see bias from bill methos reported yesterday for example). Since photon runs in tagging mode are slower and benefit from 4th spill, Luca suggest we do them overnight and use the day for electron, proton, positrons; the only concern is that positrons require a setup that is not compatible with photon runs, so is must be scheduled properly

 - 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
