Abstract

Probe measurements of plasma generated by the thermionic cathode of the axially symmetric plasma maser are performed. Emission spectra of this plasma maser are recorded in its operation mode of a noise amplifier in the frequency band from 3 to 16 GHz at the power level of ~50 MW. It is shown that violation of azimuthal plasma concentration homogeneity leads to broadening of the emission spectrum by 30 to 100% of the central frequency. A possibility is found for pulse-to-pulse electron control of the width of the plasma maser emission spectrum in addition to the electron control of the frequency.

等离子体激光器发射光谱与等离子体方位角浓度不均匀性的关系

摘要对轴对称等离子体激光器的热电阴极产生的等离子体进行了探针测量。该等离子体 maser 的发射光谱是在噪声放大器的工作模式下以 ~50 MW 的功率在 3 至 16 GHz 频段内记录的。结果表明，等离子体浓度方位角均匀性的破坏会导致发射光谱变宽，达到中心频率的 30%至 100%。除了电子控制频率之外，还发现了脉冲到脉冲电子控制等离子体激光唱片发射光谱宽度的可能性。
