Figure 1
Nearly Gaussian vertical beam profile as measured on the CLS BMIT bend-magnet beamline. The picture at the top is an image of the beam. The plot at the bottom shows the measured beam profile from that image (blue) and a Gaussian fit (red dash). The red dotted line identifies the center. The red text gives the least-squares Gaussian fitting parameters. The vertical scale is in pixel units (100 µm pixel size). The calculated beam profile is shown as the black dashed line. |
