Physical properties of laser-electron Compton scattering

The energy properties and the differential cross-sections of laser-electron-Compton scattering are quantitatively investigated. The calculations-show simple structures of the scattered photon energy and the angular distribution of the differential cross-section. At high incident electron energy, Compton scattering X-ray source has features of easily tunable photon energy and small forward emission angle. Although the dispersion of Compton scattering X-ray source is large, narrow bandwidth X-ray emission can be obtained experimentally by using specific monochromatic filter. The total cross-section and the cross-section within the forward emission angle (< 1/gamma, where gamma = E/m(0)c(2) is the total electron energy (E) in the unit of its static energy (m(0)c(2))) change slightly for different laser wave lengths and different incident electron energies in a broad range from 1 MeV to 10 GeV. They have values of 0.067 mb and 0.033 mb, respectively. The total cross-section of the visible lights is very small. These results may be useful for building new generation ultra-short X-ray source based on Compton scattering technique.Physics, MultidisciplinarySCI(E)中文核心期刊要目总览(PKU)中国科技核心期刊(ISTIC)中国科学引文数据库(CSCD)153094-31035
