Raster Size Tuning

  1. Move target to Carbon Single-Foil
  2. Request 5uA beam with 2x2 raster
  3. Start Coda
  4. Run spotL/spotR
  5. Look at BPM plots, note actual rastered beam size
  6. Request 5uA beam with modified raster size, to try to get actual raster size closer to 2x2mm
  7. Iterate 2-5 until the actual raster size is 2x2mm
  8. Move to Raster Target. Request 5uA with 2x2mm raster. Verify that rates are "Cosmic-like"
  9. Note requested "MCC Raster Size" on the whiteboard
  10. Make a HALOG entry!
