摘要
为了确定回旋行波管收集极入口的初始条件,利用CST2009模拟回旋行波管静态电子的运动轨迹,以3D模型,更直观、形象的显示出电子在回旋行波管中的运动轨迹。模拟计算表明,在电子注电压为70kV,电子注电流为10.4A,工作磁场为1.5T时,回旋行波管的电子注发射出的电子最终降落在收集极的530～700mm处。模拟结果为回旋行波管的设计和收集极的热分析提供了有效的依据。
In order to determine the initial conditions at the entrance of Gyro-TWT collector, the static electron trajecto- ries of Gyro-TWT collector is simulated by CST2009. 3D models can display the electron trajectory in the Gyro-TWT collector intuitively. The simulations demonstrate that the electron precipitates between 530mm and 700mm at the entrance of the Gyro- TWT collector under the condition that the voltage is 70 kV, the current is 10.4 A, and the magnetic {ield is 1.5T. And the simulation results provide effective method for the design of Gyro-TWT and thermal analysis of the collector.
