摘要

本文首次对并联配置的两个圆柱形反射三极管（crt）进行了模拟。细胞内粒子（PIC）模拟显示了内部和外部crt之间的耦合。在转换箔中散射的电子被用作辐射输运码Cyltran的输入。计算剂量比轴上的测量剂量小10%，与实验结果一致。用孤立的crt进行了模拟，得到的x射线剂量小于并联配置操作产生的剂量。这意味着PIC模拟中显示的crt之间的耦合产生了x射线剂量的增加。

2-D Particle-in-Cell Simulations of Two Cylindrical Reflex Triodes in Parallel

Two cylindrical reflex triodes (CRTs) in a parallel configuration have been simulated for the first time. Particle-in-cell (PIC) simulations show coupling between the inner and outer CRTs. The electrons scattered in the converter foils were used as inputs for the radiation transport code Cyltran. The calculated dose was 10% smaller than the measured dose on axis and, otherwise, agreed with the experiment. A simulation was performed with isolated CRTs, and resultant X-ray dose was less than the dose produced by the operation of the parallel configuration. This implies that the coupling between the CRTs shown in the PIC simulations produces an increase in the X-ray dose.
