  value amplifier
     Their freqencies are 27. 12 MHz and 40. 68 MHz respectively, and the maximum output power is 1. 5 -3kW. The self-excitative RF power generator is simple in structure, which is composed of reetifiersource,oscillating circuit and value amplifier. It is easy to manufacture and adjust, but the stability of the freqency and power is not so good.
     常见的高频发生器分自激振荡式和它激振荡式两种,频率为27.12MHz或40.68MHz,最大输出功率为1.5-3kW.自激式高耗发生器结构简单,均由整流电源、振荡回路和电子管放大器组成,制造调试比较容易,但是频率及功率稳定性差。

      tube amplifier
    A study is made of the effect of the parameters of a beam and a plasma-filled waveguide in a traveling-wave tube amplifier on the stability of the amplification regime against the excitation of ion acoustic waves by the microwave ponderomotive force.
          
    A mathematical model is constructed that describes the development of the beam-plasma instability in a traveling-wave tube amplifier in the presence of a neutral gas.
          
    Steady solutions are derived for conditions of microwave discharges in a magnetized plasma-filled traveling-wave tube amplifier, and their stability is investigated.
          
    The mathematical model constructed in the first part of our paper is used to numerically investigate the development of the beam-plasma instability in a traveling-wave tube amplifier in the presence of a residual neutral gas.
          
    The interaction mechanism is similar to that of a conventional traveling-wave tube amplifier or oscillator.
