未被俘获电子对多光子非线性Compton散射能量转换效率的影响

 应用单粒子理论和电子与光子非弹性碰撞模型，研究了未被俘获电子对多光子非线性Compton散射能量转换效率的影响。结果表明，未被俘获电子使该散射的频谱展宽随入射电子速度和与电子同时作用的光子数的增大而增大，随电子与光子非弹性碰撞成分的增大而减小，从而使能量转换效率近乎与电子入射速度正比降低。用低能电子入射，能有效地减小这种损失。

Influences of uncaptured electron on energy conversion efficiency of multi-photon nonlinear Compton scattering

The influence of uncaptured electron on energy conversion efficiency in multi photon nonlinear Compton scattering has been studied by using a particle theory and the inelastic collision model about electron and photon. It is found that the expansion width of the circular frequency optical spectrum of the scattered photons in multi photon nonlinear Compton effect increases with the incident electron velocity increase and the increase of the photon number by the electron absorpted at the same time,and it reduces when the inelastic collision between electron and photon increases. The expression of the direct ratio lowering of the energy conversion efficiency by electron incident speed in multi photon nonlinear Compton scattering and a method of lowering the loss with low energy electron incident have been worked out.
