Abstract
The process of radiative electron polarization through the mechanism of coherent synchrotron radiation (CSR) has been considered in the semi-classical approach. The CSR process is characterized by increasing photon emission probability from each electron proportional to number of electrons in a bunch if the wavelength of the emitted photon is greater than the bunch length. Estimations for built-up polarization of the electron beam Pcoh and the selfpolarization time Tcoh caused by CSR mechanism were obtained and the comparison with ones for incoherent synchrotron radiation was performed. Despite the low probability of spin-flip transitions a significant particle polarization can be achieved for comparatively low values of the Lorentz factor (γ ≤ 100) due to the huge number of photons emitted by each electron.
