Ion kinetics and ion sound generation under the development of modulation instability of an intense Langmuir wave in a plasma
The development of one-dimensional parametric instabilities of intense long-wave plasma waves is considered in terms of the so-called hybrid models, when electrons are treated as a fluid and ions are regarded as particles. The analysis is performed for both cases when the average plasma field energy...

Digital Library of Periodicals of National Academy of Sciences of UkraineРезюме: | The development of one-dimensional parametric instabilities of intense long-wave plasma waves is considered in terms of the so-called hybrid models, when electrons are treated as a fluid and ions are regarded as particles. The analysis is performed for both cases when the average plasma field energy is lower (Zakharov's hybrid model − ZHM) or greater (Silin's hybrid model − SHM) than the plasma thermal energy. Reduced absorption of the high-frequency (HF) field leads to the retardation of the HF field burnout within plasma density cavities and to the broadening of the HF spectrum. At the same time, the ion velocity distribution tends to the normal distribution in both ZHM and SHM. |
