Comments: 8:40 End |_ runs @ E=3.4 GeV, Ep=2.580 GeV, Theta=15.5 degree Tot # of events 27.8 M 8:43 Compton polarimeter checked the charge asymmetry prior to change the pockel cell voltage : Aq=680 ppm. 8:55 change momentum to P=2.382 GeV/c. Problem with hadron arm magnets 9:00 NMR measurement: target polarisation (transverse): 33 % 9:25 Compton checked charge asymmetry after to have change the PC cell current: -37 +/-24 ppm 9:30 BCM linearity tests + BCM calibration. Ended at 11:50 12:00 NMR: target polarisation (longitudinal) 34 % 12:20 begin \\ runs @ E=3.4 GeV, P=2.382 GeV/c 13:00 notice a light leak in the scintillators. Should not affect the data quality 13:00 pedestal run 15:15 back to // runs.
