Phase-Space Manipulations Of Electron Beams For X-Ray Free-Electron Lasers And Inverse Compton Scattering Sources., Alexander V. Malyzhenkov

Graduate Research Theses & Dissertations

This dissertation describes advanced techniques of phase space manipulations of the electron beam for improving performance and efficiency of high brightness X-ray light sources based on the free-electron Laser (FEL) and inverse-Compton scattering (ICS) processes. In particular, it first discusses a novel bunch-compression scheme based on a double transverse-to-longitudinal phase-space exchanger -- dubbed emittance exchanger (EEX) -- separated by a demagnifying transverse-optics system. While the outline of the scheme is quite sophisticated, the basic physics behind it is quite straight-forward. The benefits and disadvantages of these scheme are compared to the conventional approach of compressing a bunch using a magnetic …
