took setpoint and cycled. this magnet seems to be mismatching a lot lately, so it may be time for a trim card swap soon.

The common thread in all our efforts to minimize IDX rates has been sacrificing the linac orbits to reduce the measured radiation. Just to double check that our focus on the IDX's hasn't quietly blown the beam, took a harp swipe with IHA6E01. The horrendous orbit in figure 1 produces the trace in figure 2, not all that different from the previous swipe pictured in figure 3. IDX rates are the lowest we've been able to get all night.
