Abstract

A computational model has been developed to describe X-ray generation for energetic particle impact with surfaces in the particle simulation of plasmas. The model post-processes the energy and angular impact distribution functions and computes the emitted energy and angular spectra of X-rays. With respect to X-ray generation, bremsstrahlung radiation was described by the equations of Kirkpatrick-Wiedmann (Kirkpatrick and Wiedmann, 1945) for the bremsstrahlung cross section. The mass absorption coefficient is used to evaluate the attenuation of X-ray intensity within the impact medium. To verify the model of X-ray spectra, we compare the simulation to experimental measurements
