摘要

为了提高TE01模式回旋管行波管放大器的总效率，设计并仿真了一种两级抑制集电极。对于未使用电子的特定参数，优化了电极的几何形状和电极上的电位，以提高回旋管放大器的总效率。利用基于FTDT的电池内粒子模拟工具MAGIC 3D对抑制集电极进行静电分析，跟踪废电子轨迹。模拟结果表明，该装置的废电子能量回收率可达68.8%，总效率可达50%。

Design Studies of Two-Stage Depressed Collector for Millimeter Wave Gyro-TWT Using "MAGIC"

To enhance the total efficiency of a TE01 mode gyrotron travelling wave tube amplifier, a depressed collector with 2-stages has been designed and simulated. For a specific parameter of the unused electrons, the geometry of electrodes and potential on electrodes has been optimized to enhance the total efficiency of the gyrotron amplifier. The electrostatic analysis of depressed collector to trace the spent electrons trajectories is done by using FTDT based Particle-In-Cell simulation tool "MAGIC 3D". The simulation result of the present 2-stage depressed collector predicted 68.8% energy recovery from spent electrons energy and the total efficiency of device has been improved to ~ 50 %.
