摘 要: 根据光线追迹理论,建立一种新的调控高能X射线的光学器件——金/玻璃复合光学元件的数学模型,利用Matlab语言实现了X射线在金/玻璃复合光学元件中传输的理论模拟。通过理论模拟,得到了圆锥形金/玻璃复合光学元件对不同能量X射线的传输效率,以及高能X射线经过圆锥形金/玻璃复合光学元件传输后的光强分布情况。结果表明:金/玻璃复合光学元件既对高能X射线(E>40 keV)有明显的会聚作用,同时对低能X射线(E<40 keV)有很好的滤波作用。
关 键 词: 核物理;金/玻璃复合光学元件;高能X射线;传输效率;光强分布

Abstract: Based on the ray-tracing theory, a mathematics model for the hard X-ray transmission in a gold/glass complex optical element was built, and the theory simulation for the X-ray transmission in a gold/glass complex optical element was achieved using a Matlab program. Based on theory simulation, the transmission efficiency of conical gold/glass complex optical element with different energy X-rays was calculated and the intensity distribution of hard X-rays through transmission in a gold/glass complex optical element was obtained. The results showed that the gold/glass complex optical element could focus hard X-rays (E>40 keV) obviously and filter low energy X-rays (E<40 keV) well.
Key words: nuclear physics; gold/glass complex optical element; hard X-rays; transmission efficiency; intensity distribution
