beam current (uA): 50 uA
fast raster: 2x2mm
target: 10 cm LH2, 10 cm LD2 10 cm Dummy, C, 10B4C, 11B4C

Goal is to obtain ~5000 electrons in the range 1.5<x<1.9 for each production target.

  • Take ~1-2 hours of LH2 data to verify the position of the elastic peak at x=1. If not at x=1, correct count estimates to account for this.
  • Take data on C,10B4C, 11BC at 50 uA. Each target should take about 2.2 hours at 50 uA
  • Take LD2 data for 4 hours at 50 uA.
  • Take dummy data for at least 1 hours at 40 uA.
