论文摘要
提出了一个降低方程的系统，用于在强辐射主导的状态下用于任意电磁场配置的系统。开发的方法用于分析强尺辐射主导的电子动力学的各种情况：旋转电场和磁场中的运动，平面波中的纵向加速度以及等离子体的Wakefield中的纵向加速度。获得的结果表明，开发的方法能够描述电子动力学的特征，这对于某种情况至关重要，但不能在原始无辐射近似的框架中捕获[A. S. Samsonov等人，物理。 Rev.

A system of reduced equations is proposed for the electron motion in the strongly-radiation dominated regime for an arbitrary electromagnetic field configuration. The developed approach is used to analyze various scenarios of an electron dynamics in the strongly-radiation dominated regime: motion in rotating electric and magnetic fields, longitudinal acceleration in a plane wave and in a plasma wakefield. The obtained results show that the developed approach is able to describe features of the electron dynamics, which are essential to a certain scenario, but which could not be captured in the framework of the original radiation-free approximation [A. S. Samsonov et al., Phys. Rev. A 98, 053858 (2018); A. Gonoskov and M. Marklund, Phys. Plasmas 25, 093109 (2018)]. The results are verified by numerical integration of non-reduced motion equations with account of radiation reaction in both semi-classical and fully quantum cases.
