Image Analysis
- The viewer images were analyzed using a perl-PDL [1] package.
- The norf on images were used as a background and subtracted from the the beam on images before analysis.
- The rotation of 6degrees was applied and helped the resulting data look more symmetric when plot against K1*L.
- The region of interest for the projection was determined by first calculating the RMS and then performing a rough fit.
- With the region of interest determined, the X and Y projections were created and fit to a Gaussian distribution.
The figure below shows the projections and images (after rotation and subtraction lower left, raw image lower right) for the first quad scan perform at 4amps. This image is one of the best, but the rest of the images look very similar.
