摘要

X射线管的足跟效应是影响其性能的重要因素。为研究足跟效应对X射线能谱分布的影响

利用MCNP5软件构建了X射线管仿真模型

并设置了不同空间位置分布的探测器组

通过改变靶角、管电压和靶材料等参数研究X射线管的性能。仿真得到了靶角对X射线能谱的影响

以及在不同空间方位上X射线强度的分布

最后综合仿真结果得到了靶角、管电压以及靶材料对足跟效应的影响规律。仿真的方法和结果对X射线管的设计和使用提供了一定的理论指导。

Abstract

Background

Heel effect of X-ray tube is an important factor which would affect its performance

especially for reflective X-ray tube.

Purpose

The study aims to research the impact of heel effect on X-ray spectral.

Methods

MCNP5 is adopted to create simulation model of X-ray tube and set up detector groups following different spatial position distribution. Then the performance of X-ray tube is analyzed by changing the parameters including target angle

tube voltage and target material.

Results

Simulation results show the impact of target angle upon X-ray spectral and X-ray intensity distribution in different spatial positions. In the final stage the impacts of target angle

tube voltage and target material on heel effect are shown.

Conclusion

Methods and results of this simulation provide certain theoretical guidance for the design and use of X-ray tube.
