摘要
在高能闪光照相技术中，高能X射线的能谱测量一直是一个难点。在以往研究方法的基础上，指出控制散射的影响程度是提高能谱测量精度的关键。提出采用圆形阵列法对X射线能谱进行测量，并针对一特定能谱的X射线设计了测量装置，蒙特卡罗模拟结果表明，可以将散射的影响控制在4%以内，这对提高能谱测量精度具有十分重要的意义。
Abstract
Measurement of high-energy X-ray energy spectrum is difficult in high-energy flash X-ray radiograph. According to previous studies, controlling the influence of diffusion to a certain extent is very important to improve the precision of energy spectrum measurement. In this paper, circular array method (CAM) is introduced to measuring X-ray energy spectrum. An experiment setup is designed. Simulation from Monte-Carlo suggests that it is possible to control the influence of diffusion within 4%.
