Abstract


With the energy crisis growing, enabling mankind to seek new energy hasbecome inevitable. With laser technology, the development of inertial confinementfusion and broad prospects for ever-increasing importance.In 1952, the Americanmade the "Project Sherwood" for developing the controlled thermonuclear reacto.Then, all sizes of laser devices were competing to establish. Right-laser ablationpellet process of a detailed study inevitable. Due to the continuous laser intensityincreased, and therefore the process of the plasma to relativistic effects involved isan indisputable fact, so relativistic plasmas should be studied. And relativisticparticles (electrons) in the energy measurement, it has become inertial confinementfusion projects in the important subject.For this special medium, plasma, there are many types of treatment.Thebehavior of plasma is essentially a collective effect. It needs statistics physicalmethod to deal with, and it can also use approximate processing method to study.Generally approximate method is divided into single particle method and fluidmethod. Here we mainly introduce single particle method. It considers plasma as anindependent particle system, and the moving orbit of single particle in electronmagnetic field can be determined in terms of the moving equation. Firstly, thecondition of the method is that the interaction among the particles can be neglectedcompletely. Secondly, the influence of the electric current on the external magneticfiled is not considered. With the continuous development of the computer technology,we probably calculate the moving orbit of the charged particle in the complicatedpatterns of the electromagnetic field. However the complicated pattern of theelectromagnetic field can include the influence of the electric current caused by themovement of the charged particle on the magnetic field. Therefore the secondcondition seems to be not very necessary. The single particle method is best suited todescribe the thin plasma.Based on single particle method, the use of the method of Mr.Li -the chargedparticles on the spontaneous radiation theory numerical analysis, and get thefollowing results:1. Trajectory of Compton radiation of relativistic particles 2. Radiation energy Spectrum of Compton radiation of relativistic particles
