摘要：
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.
