摘要

采用粒子模拟,得到了阳极杆箍缩二极管阳极钨针上电子的空间分布和入射角分布,分析二极管工作状态得到了电子的能量分布.在此基础上建立阳极杆箍缩二极管的蒙特卡罗模型,模拟得到了阳极杆箍缩二极管的辐射能谱和X射线的平均能量,并与实验结果进行了比较.结果表明:09006炮光子平均能量为0.441 MeV,计算该能谱射线经过不同厚度铅衰减片后的剂量衰减情况,与叠片法PIN探测器所测的实验数据基本一致.

By particle-in-cell (PIC) simulation and theoretically analysis, electron spatial distribution and energy distribution in the rod surface of rod-pinch diode(RPD) are obtained separately, as input parameters for Monte Carlo simulation of photon energy spectrum of X-ray emitted from RPD. The Monte Carlo simulation results show that the average photon energy of shot 09006 is 0.441 MeV. Taking account of Pb attenuator, the simulation results accord with experiment data detected by PIN detectors array.
