Analysis and interpretation of e-beam profile data for EBTS for HEL

This report includes answers to the questions of what is Hollow Electron Lens Project, what is tested in Electron Beam Test Stand and how does the algorithm of the beam image analysis script work, respectively. Under the section of Electron Beam Test Stand (EBTS), the motivation for EBTS and basic working principle regarding specific subsections for essential parts of the EBTS are introduced. Afterwards, under the section of Analysis of the Electron Beam, the methodology of the analysis script and the results from these analysis are presented. In the last section, future measurements and next phases of EBTS are described.
