摘要: 运用大轨道电子束，对外开槽同轴波导回旋自谐振放大器进行了线性动力学理论分析和非线性自洽模型模拟。由线性动力学理论分析和非线性模拟得到的结果在线性增长部分吻合得很好。为了有效抑制绝对不稳定性，对电子束流的选择进行了讨论。计算结果表明：对于电压为700 kV, 电流为100 A, 电子束纵横向速度比为0.8的大轨道电子束, TE51外开槽同轴波导回旋自谐振脉塞放大器的峰值功率和峰值效率分别可以达到6.27 MW和8.96%。

Abstract: The linear kinetic theory and nonlinear self-consistent model for outer-slotted-coaxial waveguide cyclotron autoresonance maser(CARM) amplifiers with axis-encircling beam are presented. Good agreement is found between the simulations and the kinetic theory in the linear regime. The choice of the electron beam current is discussed for suppressing the absolute instability. Using a 700 kV, 100 A axis-encircling beam with electron beam velocity pitch of 0.8, nonlinear self-consistent analysis predicts that TE51 CARM amplifier can have a peak output power of 6.27 MW and a peak efficiency of 8.96 %. -
