Abstract:
Effects of electron beam parameters, including energy, radius and emittance, as well as target parameters, on bremsstrahlung exposure are discussed in this paper.With the energy of incident electrons varying from 2MeV to 50MeV, the forward yields at a distance of one meter from different targets, such as tungsten, copper, tantalum and aurum, are calculated by both analytical formula and MCNP4 Monte Carlo code. In addition, the relationship of X-ray dose to target and electron parameters is analyzed. The results agree well with published experimental and theoretical data,and may be a good reference for the design of this kind of X-ray source.
