Outline of Final Research Achievements

Edge radiation is produced from a relativistic electron beam passing through an edge of a bending magnet and has specific polarization property called “radial polarization”. We studied on generation of monochromatic coherent edge radiation in THz region aiming its applications. The experiments were carried out at UVSOR storage ring. The monochromatic coherent edge radiation is emitted from a density modulated electron bunch via the interaction between the electron bunch and an amplitude modulated laser. We have installed a beam port for the observation and succeeded in measurement of spectral and special distribution of the radiation.
