Abstract

In this paper, by using the electron spectra resulted from the laser– plasma interaction, the production of Bremsstrahlung X-ray radiation in different targets will be simulated by using MCNP code. The purpose of this work is to achieve the optimum material for the purpose of optimum thickness for high efficiency production of X-rays to obtain an optimum angle X-ray emission from the target to produce x-ray flux to achieve the optimum electron spectrum for medical applications and production of neutrons. The results show that the maximum electron energy increases, the optimum thickness to increase output efficiency. For materials with higher density, an increase of the Bremsstrahlung photon emission occurs at lower thickness and higher flux of neutrons is observed.
