Cusptron振荡器的分析与计算

Analysis and Calculation of Cusptron Oscillator

本文对Cusptron进行了理论研究。首先分析了在cusp磁场中电子的运动。在此基础上研究了电子注与驻波场的互作用。在f_o=35GHz对16个翼片的磁控管型腔中H_(511)π摸与电子注互作用(8次回旋谐波)进行了数值计算。考虑了电子注中速度分布、注厚度以及B_k≠B_o等因素对电电效率的影响。

Cusptron is studied theoretically in this paper. First of all, electron motion in cusp magnetic field is analysed. On the basis of this, the interaction between electron beam and standing wave field is investigated. The interaction between H811 π mode in magnetron structure with sixteen vanes and electron beam at eighth harmonie of the electron cyclotron frequency is calculated numerically at f。 = 35GHz. The influences of electron velocity distribu-tion in the beam, the thickness of beam and BK≠B。 on electron efficiency are taken into consideration.
