Attached is an RGA scan of the Y-end taken this morning (RGA parameters are not optimized for current conditions but, rather, are left unchanged from initial scans for comparison purposes).   

I changed the programmed pump current value at which point IP11 "steps" from 7000V to 5000V from 5x10-4 amps to 1.5x10-3 amps.  Prior to this change the pump current was 1.4x10-3 amps @ ~8.5x10-8 torr.  The result is that IP11 is now at 5000V.
