keyword=BigBite Raw Trigger Asymmetries Near Spot MoveYou can see that the asymmetry increases about 2.4% (relative) from before and after the HWP/spot move on Friday. NMR at 8:00AM (run 2263), 12:00PM (2273), and 4:00PM (2281) give 62.0, 62.1, and 61.7%, so this does not correspond to changes in target polarization. Charge asymmetry feedback has been keeping things less than about 100ppm and has been centered around 0. This points to increased beam polarization.
