多光子非线性Compton散射对等离子体中颗粒成长的影响

应用等离子体颗粒成长模型和多光子非线性Compton模型，研究了多光子非线性Compton散射对等离子体中颗粒成长的影响。提出了将入射光和多光子非线性Compton散射光作为颗粒成长的新机制，对颗粒凝合截面、凝合系数、颗粒收集的电子流和离子流的表达式进行了修正。结果表明，等离子体参数的变化与多光子非线性Compton散射成分、电子散射前的初始速度、入射角、与电子同时作用的光子数等因素有关。散射使生长过程中收集离子机制和凝合机制增强，颗粒的凝合截面增大，颗粒半径较快的非均匀增长。

Influence of granular growth in plasma by multi-photon nonlinear Compton scattering

Using the model of the granular growth in the plasma and the model of the multi-photon nonlinear Compton scattering, the influence of granular growth by the multi-photon nonlinear Compton scattering has been studied. A new mechanism of the granular growth formed by the incident light and the multi-photon nonlinear Compton scattered optical has been given out. The formulas of the coagulation section of granular, coagulation coefficient, the electron current and ion current collected by the granular have been revised. The result shows that the changes of the plasma parameter have the relations with the inelastic scattering composition between electrons and multi-photon groups, the initial speed of the electron before the scattering, its incident angle and the photon numbers of the action at the same time with electrons, et al. The mechanisms of the collecting ions and coagulation are increased by the scattered. The coagulation section and radius rate of rise of the granular are increased, and the granular radius is quickly and no-evenly increased.
