摘要
借助3维粒子仿真软件对一种新型18叶片5.8 GHz磁控管进行了动态模拟,比较了爆炸式发射与电子注发射的不同。利用磁路电子注发射方式针对不同的阴极发射电流进行了动态模拟,得到了不同发射电流条件下磁控管的工作特性。同时,利用FEMM仿真软件对磁控管磁路进行了仿真,得到了磁控管互作用空间的磁场分布,并在此基础上,对非均匀磁场下磁控管动态性能进行了模拟。
With three-dimensional particle simulation software, a new type of 18 vane 5.8 GHz magnetron has been simulated. The differences between explosive emission and beam emission are compared. Using beam emission models, the influence to the magnetron characteristics by the cathode current destiny can be obtained. At the same time, the magnetic field distribution can be obtained using simulation software FEMM. On this basis, hot test simulation has been performed under non-uniform magnetic field condition. With the research provides a basis for developing 18 vane 5.8 GHz magnetron.
