Effects of polarization parameters on the motion and radiation characteristics of high-energy electrons

In order to explore the gradient changes of super laser polarization parameters based on the high energy electron motion and the influence of radiation characteristics, based on the basic equation of electromagnetism, a relativistic electron acceleration model was derived and set up with the initial momentum of 0. Then a numerical simulation program of no approximation was developed for iterative calculation and theoretical analysis. Visualized data of single electron motion and space radiation under different polarization parameters were obtained. The results show that with the increase of the polarization parameter δ from 0 to 1, the trajectory of the electron gradually changes from 2-D plane oscillation to 3-D spiral, and the amplitude of rotation increases gradually, and the trajectory projection tends to be positive circle. The spatial distribution of electron power radiation gradually changed from planar linear to 3-D vortex, and gradually changed from up-down needle-like bifurcation to smooth connection. The general change trend can be divided into four stages according to morphology: δ=0, δ∈(0, 0.6, δ∈(0.6, 0.99 and δ=1. The results provide a theoretical and numerical basis for the study of high-energy electron radiation from multiple perspectives, and are helpful for the accurate detection of super-strong laser parameters in practical applications.
