  • Determine the intrinsic beam spot size by performing a HARP scan. Ask MCC to take harp scans on Harps A and B (IHA1H04A and IHA1H04B) and ask them to post the results to our logbook Halog.
  • When the results arrive fill in the green blanks in "Beam spot size at target" section of this spreadsheet and report/halog the values of the spot size calculated which show up in the red blanks.
  • If either of the Xsigma and Ysigma spot radii (1 sigma) is less than 320 microns, ask for optics adjustment.
