keyword=spot++ after MCC steering
spot++ again after MCC steering to center beam on holey Carbon. Run 24852. Raster still 10 by 10 because MCC (and Jay) says that is the highest they can push it.
The y position is well centered now and the x position is more or less as it was before (almost centered but slightly off--the BPM positions are within 0.1mm of our golden positions).
However, the hole is distorted (elongated in x)...interesting...
We will ask MCC to move the beam +0.5mm in x and do another spot. Then we will put the Hydrogen target in and goto 100uA and do a boiling study.
