| 摘 要： | 根据二极管结构及运行参数与出射电子、光子能谱的关系，采用Matlab数据处理软件和蒙特卡罗粒子输运计算方法，建立了二极管阳极靶表面出射光子能谱的计算方法。通过多次对二极管单次脉冲运行参数的比较研究，分析了强流二极管多炮运行参数的波动，对所产生的脉冲X射线能谱场稳定性的影响。计算结果表明：电子能谱的差异随着二极管运行的电参数变化而变化，每炮光子能谱谱型的差异趋于减小。当运行参数波动不大时，能谱场稳定性较好。

| Abstract: | The spectrum of incident electrons and emitted photons on the anode surface of the diode were calculated and analyzed by Monte Carlo Code MCNP/4C and Matlab, according to relations between the structure, operation parameters of the diodes and emitted electrons and photons spectrum. The parameters for single pulse obtained by several shots were compared, and the distributions of the electron and photon spectrum generated by each shot were calculated. It was investigated that variations of the electrical parameters in the operation of the intense diode influence the stability of the pulsed X-ray spectrum. The result shows that the stability is good with small variations of the electrical parameters of diode. |
