Simulation of X-ray Parameters via Thomson Scattering

In this work, a computer program has been built to simulate some important X-ray parameters via Thomson scattering. X-ray energy dependence on the emitting and x-ray scattering angles for different incident electron energies were obtained. From this simulation, the X-ray energy was found to be distributed around (-1 o to +1 o ) for X-ray emitting angle. Also it was found that, the X-ray peak energy was increased by increasing the scattering angles. An effort had been made on the angular frequency shift dependence on the scattering angle and laser photon energy. It had shown that the angular frequency shift was more dependent on laser photon energy rather than the scattering angle. 1Introduction: Thomson scattering is an important phenomenon via plasma physics and was first explained by physicist J.J. Thomson. Thomson scattering Xray based on the interaction between relativistic electron beam and high Simulation of X-ray Parameters via Thomson Scattering. 60 power laser pulses will provide a powerful tool for modern scientific research, due to its advantages over traditional light sources. Such as; good directional radiation, high brightness, wavelength tunability and very short pulse in the picoseconds and femtoseocnd region [1,2]. The generation of x-ray radiation pulse have been attracted much attention since it could be a unique to investigate ultrafast dynamic process in nature such as the motion of electron in atoms [1,2]. A short pulse X-ray sources is required in various research fields such as material, biology and medical science. The X-ray generation source via Thomson scattering using picoseconds and femtoseocnd laser light was developed and reviewed extensively by [2-9]. In this paper, a simulation had been made for Thomson scattering to obtain the X-ray energy dependence on the emitting and scattering angles for a wide range of different relativistic electron energies. Angular frequency shift depending on the scattering angle and laser photon energies were performed. The dependence of peak frequency shift on the incident electron energies was revealed. 2Theory: The generation of X-ray in the Thomson scattering (inverse of Compton scattering) can be obtained when a beam of relativistic electrons are collided with a laser light. The interaction geometry of Thomson scattering is shown in Fig.(1). Fig.(1): Interaction geometry of Thomson scattering. Laser beam
