Abstract: (3298 Views)
Progress on high-power lasers with ultrashort pulses has been opened a new horizon to the laser-material interaction. One of the applications of laser- plasma interaction is acceleration of relativistic electrons. The collision of these energetic electrons with a secondary target, results in the characteristic and Bremsstrahlung x-rays generation. By calculating the output current via MCNP4C simulation code, the effect of angular distribution of the colliding electrons on raising the x-ray efficiency is considered. The results of simulation reveal that changing the entrance angle of the electrons has an important role on increasing the efficient photons current.
Keywords: Quasi-monoenergetic electrons, entrance angle of electrons, simulation of x-ray generation.
