Smooth data taking, Hydrogen asymmetry measurement w/ longitudinal holding field still reveresed. WC segments L6 and L21 tripping frequently (~1-2 min for L21). Reduced L21 voltage to 3750V, now tripping evry ~10-15 min, quite manageable.
Compton running, but now see a false asymmetry again between the two helicity states (pol_+=0.65 and P_-=0.44), may be Bill needs to readjust the laser beam. Jan v. Laan checked the compton BPM position, within 1/2mm of nominal.
