  • 本論文探討了 mode 磁旋管在大迴旋半徑下不同機制引起的群聚效應之間的關係,得到在TM mode的情況的四個群聚效應點在實空間的位置關係,並且利用商用軟體CST去模擬一個TM mode gyrotron得到在91.5GHz的時候得到,14%的效率。並從其中發現對於TM mode磁旋管而言,從軸向電場損失的z方向動量會從橫向的動量利用磁場補回。


    This thesis discuss the bunching mechanism in a mode system which operate at harmonics equal to 1. Here I introduce the CST (Computer Simulation Technology) to simulate a TM-mode gyrotron operating at mode. The electron beam voltage of 70 kV, and current of 5A with a pitch factor of 1.5 are assumed. The output power is 44kW centered at 91.5GHz. CST’s result shows that E_z will consume p_z but B_⊥will replenish.
