旭日型相对论磁控管的三维模拟

Three-Dimensional Simulation of Rising-Sun Relativistic Magnetron

摘要: 用两种3 维全电磁PIC 方法对10 腔旭日型相对论磁控管进行数值模拟。首先用MAGIC 对管子进行模拟，模拟结果表明：当工作电压为634 kV、磁场为0.53T 时，通过模拟该磁控管得到频率为2.6 GHz、平均功率为1.91GW的微波输出,平均效率为16.9 %。接着基于CHIPIC 平台进行模拟，通过与MAGIC 模拟结果进行对比，验证了CHIPIC在相对论磁控管中模拟的可行性，只是发现CHIPIC 在傅里叶变化命令设置上有些问题，需要进一步完善。

Abstract: 10 cavities rising-sun relativistic magnetron is simulated through two kinds of 3-D particle-in-cell (PIC)electromagnetic codes. First of all, the tube is simulated with the MAGIC, simulation results show that: when the working voltageis 634kv and the magnetic field is 0.53T, a frequency of 2.6GHz, average power of 1.98GW microwave output is generated fromthe magnetrons by simulation. The average efficiency is about 10.2%. Then based on CHIPIC platform，the tube is simulated.Compared with the MAGIC simulation results verify the feasibility of the CHIPIC simulate in relativistic magnetron, only to findCHIPIC command set in the Fourier transform exits problem and needs further improvement.
