Abstract

For the sake of studying the initial position's influence of electrons on the trajectory and spatial angular radiation of high-energy electrons in circularly polarized laser pulses, the spatial motion equation of high-energy electrons was deduced theoretically on the basis of nonlinear Thomson scattering model, energy equation, Lagrange equation, and in combination with the assistance of MATLAB numerical simulation, the spatial motion trajectory diagram and spatial angular radiation simulation diagram of high-energy electrons made. The results show that, under the action of the transverse vortex force, the front trajectory of the electron in the whole space is in a tightly separated spiral shape, and the rear trajectory is composed of sparse circles with distant spatial spacing. With the right shift of the initial position of the electron, the value of the polar angle θ and azimuth ϕ has a decreasing trend when the spatial angular radiation reaches the maximum. Specifically, it becomes stable when z₀=5λ₀ and (θ, ϕ)=(23.5°, 175.5°). Therefore the change of the initial position of the electron in the laser pulse has a great influence on the trajectory and spatial angular radiation of the electron, which creates the groundwork for the subsequent research of the initial position's influence of the electron on the radiation characteristics of high-energy electrons.
