摘要

研究了在二次衰变过程中激发离子伯恩斯坦(IB)波的局域化效应，以及伴随异常泵浦波低阈值参数衰变不稳定性的发展，导致异常波和等离子体中局部化的上杂化(UH)波的激发。结果表明，在电子回旋共振等离子体的二次谐振加热实验中，发现的效应使初级不稳定饱和水平和泵浦波的异常吸收水平都有所降低。

On the Issue of Possibility of Reducing Anomalous Absorption of Extraordinary Pump Wave in a Wide Range of Plasma Densities

The consequences are studied of the localization effect of ion Bernstein (IB) waves excited in secondary decay processes accompanying the development of low-threshold parametric decay instability of the extraordinary pump wave, which results in the excitation of the extraordinary wave and the upper-hybrid (UH) wave localized in the plasma. It is shown that in experiments on electron cyclotron resonance plasma heating at the second resonance harmonic, the effect discovered results in a decrease in both the saturation level of primary instability and anomalous absorption level of the pump wave.

期刊介绍： Plasma Physics Reports is a peer reviewed journal devoted to plasma physics. The journal covers the following topics: high-temperature plasma physics related to the problem of controlled nuclear fusion based on magnetic and inertial confinement; physics of cosmic plasma, including magnetosphere plasma, sun and stellar plasma, etc.; gas discharge plasma and plasma generated by laser and particle beams. The journal also publishes papers on such related topics as plasma electronics, generation of radiation in plasma, and plasma diagnostics. As well as other original communications, the journal publishes topical reviews and conference proceedings.
