170 GHz回旋管是等离子体核聚变中电子回旋谐振加热的理想功率源,在功率上要求具有1 MW以上的输出功率.要产生这么大的输出功率,就需要具有足够大横向能量的电子注与高频场的横向电场进行互作用,因此要对电子枪进行专门的设计.利用绝热压缩理论及相关的仿真软件对双阳极磁控注入电子枪进行了设计,得到了较好的电子注参数.所设计的电子枪能在工作电压80 kV、工作电流40 A 的条件下为170 GHz 基波回旋管提供所需的回旋电子注,其引导中心半径为8.27 mm,横纵速度比1.5.

A 170 GHz gryotron is an ideal power source for the Electron Cyclotron Resonance Heating (ECRH) in the plasma fusion. The required output power from a single gyrotron tube at 170 GHz operating frequency for ECRH application is 1 MW or more. For generating the high output power,a Magnetron Injection Gun(MIG) which can provide the electron beam with large enough transverse energy for interacting with the transverse filed of the electromagnetic wave is designed. Ideal parameters of the double-anode MIG are obtained according to the adiabatic compression theory and the correlative simulation software. The designed MIG can provide the necessary beams for the 170 GHz fundamental harmonic gyrotron under 80 kV of voltage and 40 A of current with the guidance center radius of 8.27 mm and the pitch factor of 1.5.
