Abstract- The quasi-monoenergetic electrons produced by laser-plasma accelerators collide with slab solid targets and the generated x-ray is simulated by MCNP4C code. In this work, the effects of electron profile parameters such as pulse-width (ΔE), energy of the peak (Ep), and total energy of electrons (Et), electron beam dimension, plus material and thickness of target are studied on x-ray efficiency. It is resulted that in thicker targets, by using an electron source with smaller diameter, larger Ep and smaller ΔE, also a target with larger atomic number and density, x-ray efficiency is increased.
