X- Ray generation via Thomson Scattering

In this paper, a theoretical simulations had been made via Thomson scattering to determine the number of photons of x-ray emitted per solid angle for a wide range of angles of observation of x-ray. This study had been carried out at fixed scattering angle equal (90°) and different relativistic electron velocities. Also, an independent study had been performed to determine the frequency shift for different scattering angles and using two laser photons wave lengths (1.064 m and 0.8 m ). Furthermore, another simulation had been carried out to determine the dependence of peak frequency shift on incident electron beam energies. Introduction: A short pulse x-ray source was developed by Thomson scattering (inverse compton) via the interaction between relativistic electron beam and laser light. The mechanism of explaining such process that the XRay generation via Thomson Scattering. 109 electric and magnetic components of incident wave accelerate the particle. As it accelerates, it in turn emits radiation in the x-ray region [1]. A short pulse x-ray source is considered an important probes for study the dynamics of the material and structure of solid, industrial applications and medical imaging applications compared to other light sources such as Ti:s laser of wavelength (800nm) [2,3]. The x-ray generation of Thomson scattering has many important advantages such as a good directional radiation, high brightness, tunable wavelength and the intensity of x-ray is proportional to densities of both electron and laser beams[4]. X-ray sources had been the subject of different researches groups[5-10]. In this work, a computer program was built for Thomson scattering simulation to determine the number of x-ray photons emitted per solid angle over different angles of observations. Knowing that this study had been carried out at a fixed scattering angles equal (90°) and for different electron velocities. In addition, a study was made to determine the frequency shift for different scattering angles. Theory A schematic configuration of thomson scattering is shown in fig (1). Electron beam Laser beam
