高能闪光X射线能谱的空间分布特征

Spatial Distribution Characteristics of High-energy Flash X-ray Energy Spectrum

高能闪光X射线是闪光X射线照相的主要手段,而高能闪光X射线的属性参数会影响到闪光X射线照相的实际结果,其中最为重要的属性便是能谱。能谱的空间分布特征可以有效地帮助实际测量装置的结构设计,获取最佳的测量效果。Geant4是国际上通用的高能物理模拟系统,在轫致辐射理论的基础上,使用其对实际场景进行了细致模拟,从而得到高能闪光X射线能谱在空间上的分布特征。

The high - energy flash X - ray is the primary means of flash X - ray radiography, and the properties of high - energy flash X - ray affect the performance of flash X - ray radiography. Energy Spectrum is the most important attribute of high - energy flash X - ray, the spatial distribution characteristics of The energy spectrum can be used to design the structure of the actual measurement device and effectively help to obtain the best measurement results. Geant4 is a common high - energy physies simulation system, with Geant4 and the theory of bremsstrahlung, the actual measurement scene is given to a detailed simulation which obtained the distribu- tion of eharaeteristies of high - energy flash X - ray.spectroscopy in space.
