摘要

本文采用非线性自洽仿真程序对系统的绝对失稳进行了分析。该程序基于弱非均匀相互作用结构中的稳态粒子跟踪技术，适用于放大器的输出功率、陀螺- bwo的起振荡电流和反射振荡。如果不稳定带延伸到前向波和后向波区域，则会提供一个内部反馈，导致绝对不稳定。

Nonlinear analysis of absolute instability in gyrotron traveling wave amplifiers

This study analysis the absolute instability by using a nonlinear self-consistent simulation code. The code is based on the technique of steady-state particle tracing in a weakly nonuniform interaction structure and appropriated for output power of amplifier, start-oscillation currents of gyro-BWO and reflective oscillation. If the unstable band extends to the forward and backward wave regions, there will provide an internal feedback to result in the absolute instability.
