Position Scan Run Plan
The point of this scan is to make sure that we are not hitting the
aluminum with the beam. This should take 2 - 3 hours.
- Start at nominal run position, centered on the C-hole target.
- Try to get raster to 6 x 6 mm.
- Then:
- Turn on S0 HV on left arm
- Take spot++ at ~10 uA.
- Verify raster size, also uniformity of shape (usual
bedposts, no
other structure evident)
- Turn OFF S0 HV on left arm.
- Take 15000 Good pairs at ~95 uA.
- Repeat steps 1) and 2) at each of 4 positions, +/-1 mm in x, +/-1mm
in y
from nominal.
