低磁场回旋速调管的空间电荷效应

THE SPACE CHARGE EFFECT OF LARGE-ORBIT GYRO-KLYSTRON

本文建立了考虑直流空间电荷效应和交流空间电荷效应的低磁场(大回旋半经)回旋速调管扰动理论。在漂移区中考虑直流空间电荷场的影响。我们发现电子运动在该区服从一振荡方程;进一步在输出腔中计及了交流空间电荷场对注一波换能的影响。文中求得了相应的电子群聚、注一波互作用功率及增益的表达式,并进行了讨论。

The Perturbation theory of large-orbit gyro-klystron with inclusion of DC space charge effect and RF space charge effect is presented in this paper. We find out that, in drift, region, the motion equation of electron is an oscillation one, which influences the prcbunching of electrons. Furthermore, We consider the function of RF space charge effect on beam-wave interaction in output cavity. We also derive out some useful expressions, such as electron bunching, beam-wave interaction power and gain, and carry...
