Beam quality has been poor preventing smooth data taking. For the remaining kinmatics, we anticipate only getting about 50% of the orginially planned data.
Beam use: Shift ABU BANU BNA 2009/02/28 swing 4.5 1.0 2.5 2009/03/01 owl 2.5 0.6 4.9 2009/03/01 day 4.0 1.1 2.9 TOTAL 11.0 2.7 10.3 ____ Main events:
Feb 28:
Production on 5-pass Kin I, p0 = 1.34 GeV/c Beam quality is very poor due to RF problems, injector problems, and vaccuum problems.
March 1:
Brad and Kalyan opportunistically added preshower to T6 trigger for explicit pion rejection, increasing data taking rates.
Had left Q1 trip at 8:00 due to low liquid levels. Brad noticed that the readback levels were fluctuating significantly.
No Compton data from 7:00~13:00 due to Compton DAQ problems.
14:50 - Switching to Kin G
____ Plans until Beam Studies 3/3:
Continue production until Monday, 3/2 6:30am 6:30, go to controlled access for techs to swich LHRS polarity
9:00-17:00 - 5 pass positron data
19:00 - Moller
Finish as much 5 pass pass production as possible until beam studies Tuesday
