Analysis of the Effect of Pulse Length and Magnetic Field Strength on Nonlinear Thomson Scattering
Source abstract
Abstract
In this paper, two parameters of the applied magnetic field—magnetic field strength and pulse length—are modified, the spatial properties of electron trajectories and radiation are studied, and conclusions are drawn. Under the premise that the radius of the laser pulse waist b0=4λ0, and that the peak amplitude a0=5 corresponds to the peak laser intensity IL=3.45×1019 W/cm2 of the electrons, obtaining high-energy and highly collimated X-rays can be realized by increasing the pulse length up to 6λ0 and increasing the magnitude of the applied magnetic field, or by continuously increasing the pulse length and applying a smaller magnetic field.
