A change in the operation mode of a plasma maser with a pulse duration of 40 ns from a noise amplifier to a feedback self-oscillator at a power level of up to 10 MW has been experimentally demonstrated for the first time. In the noise-amplifier mode, the radiation power is distributed almost uniformly in a frequency range from 3 to 9 GHz. In the self-oscillator mode, the emission spectrum contains characteristic frequencies of longitudinal oscillation modes of plasma—beam cavity.

Plasma Maser中的反馈

首次通过实验证明了功率为10 MW的等离子体激射器的工作模式从噪声放大器到反馈自激振荡器的脉冲持续时间为40 ns的变化。在噪声放大器模式下，辐射功率在3至9 GHz的频率范围内几乎均匀分布。在自振荡模式下，发射光谱包含等离子束腔的纵向振荡模式的特征频率。
