Development of an optical transition radiation beam monitor for free-electron lasers

Abstract

An optical transition radiation (OTR) beam monitor has been developed for the beam diagnostics in free-electron lasers experiments. The OTR lights from an aluminized synthetic quartz screen under passage of the 12 MeV electron beam from the RF linac at University of Tokyo were observed with an Intensified-CCD(I-CCD) camera. The spatial profiles of the beam were measured when the camera was focused onto the screen, while the OTR angular distribution patterns were measured at the infinite focal length. The beam energy and divergence were also obtained through the analysis of these patterns. (author).
