Abstract
Spectrum degradation methods of pulsed hard X-ray by optimum design of bremsstrahlung convertor were introduced based on bremsstrahlung principal .Output parameters of composite convertor and reflection convertor were simulated by using MCNP code .Influence of convertor thickness on spectrum ,conversion efficiency of X-ray and transmission electron quota was analyzed . The difference of spectrum and conversion efficiency between transmission and reflection X-ray of reflection convertor and the change law of these parameters according to electron incidence angle were presented .Experiments of two convertors with different thickness were carried out ,and the experimental result is close to simulation result . These methods can be used to degrade spectrum of pulsed hard X-ray .关键词
