High-order corrections to the radiation-free dynamics of an electron in the strongly radiation-dominated regime
arXiv:2208.00673 · doi:10.1063/5.0117504
Abstract
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.
