摘要: 激光同步辐射光源是一种新型的X射线光源,它利用高强度激光与相对论电子束发生康普顿散射,从而在电子的运动方向上辐射出X射线.本文在考虑电子的反冲基础上,利用康普顿散射研究了激光同步辐射光源(LSS)辐射光子的精确波长和能量;同时发现,对于背散射情况,只有当种子激光的波长λ1大于电子的物质波波长λm时才能发生LSS辐射;最后给出LSS辐射的极值波长λ2max=h/(m0γv)和极值能量εc2max=βε3.

Abstract: Laser synchrotron source is a novel X-ray source. LSS is based on Compton scattering of intense lasers from relativistic electron beams. By Compton-recoil electron method, the wavelengths and energies from the laser synchrotron source are investigated. The results show that, for the different y ranges, the wavelength and energy have the different approximate formulas. Then, the radiation condition of the LSS is calculated as λ1 〉λm. At the last, the relation λ2max = h/(mo γv) and εc2max=βε3 are presented.

Key words: laser synchrotron source, Compton scattering, recoil electron, wavelength, energy
