Compton散射下激光等离子体与自生磁场对电子的加速

Electron Accelerator by Laser-plasma and Self-Magnetic Field under Compton Scattering

应用电子与多光子集团非线性Compton散射模型,对多光子非线性Compton散射下激光等离子体和自生磁场对电子的加速进行了理论分析和数值模拟.结果表明,不仅由Compton散射光与入射光形成的耦合光以及耦合光与等离子体相互作用形成的自生磁场所构成的混合场能使做回旋共振运动的电子在较短的长度内加速到很高的能量,而且注入电子的初始参数及耦合光的参数对电子加速亦有较大影响.

Using the nonlinear scattering model between an electron and multi-photon group,we have given out the electron acceleration by laser-plasma and self-magnetic field under multi-photon nonlinear Compton scattering,and have studied the scheme using the means of theory analysis and number simulated.The results show that not only the coupling optical formed by scattered optical and incident optical,and the mixed field formed by coupling optical and laser self-magnetic field formed between coupling optical and plasma can accelerate the circle resonance electron to the higher energy in shorter length,but also the initial parameters of the incident electron and the parameters of high power coupling laser have bigger influences to the electron acceleration.
