Running on ABS deuterium. ligit is about 1.8E-7 now. Ring is filling to 160 mA. Lifetime starts at about 12 minutes, gets to about 21 minutes at the bottom of the fill. Red needle is at 275 C/hr, with some time lost to occasional HV trips. Beam is a bit unstable sometimes.

The objective for the overnight is to run ABS deuterium, and make sure the autocruncher is running. When the first runs finish crunching, run show_deep_asym_all and ed_xs to get target polarizations and target thickness.

Dave will try some gentle beam tuning while we take data to improve the lifetime at the beginning of the fill, and also the beam stability.
