PASOTRON注波互作用线性理论研究

STUDY ON THE LINEAR THEORY OF BEAM-WAVE INTERACTIONS OF PASOTRON

该文研究了等离子体辅助慢波振荡器(Plasma Assisted Slow-wave Oscillator,PA-SOTRON)的物理机制;在考虑离子通道的情况下,利用线性场理论,推导了无引导磁场下等离子体填充的波纹波导中电磁波传播的色散方程;并通过数值计算分析了等离子体填充因子对PASOTRON的时间增长率及工作频率的影响。

The physical mechanism of PASOTRON (Plasma Assisted Slow-wave Oscillator) is studied. Taking into account the ion channel and making use of the linear field theory, the dispersion equation of corrugated waveguide filled with plasma is derived without a guiding magnetic field. It is analyzed by numerical computation that the temporal growth rates and the frequency of PASOTRON are affected by the filling factor of plasma.
