Abstract

The instability of dusty sound in plasma with a directed ion flow is investigated. This instability develops when the frequency of dust oscillations coincides with the frequency of ion oscillations. Characteristic frequencies and growth rates of the most unstable oscillations are obtained. It is shown that the interaction of waves in the nonlinear stage of instability development results in the formation of dust blobs elongated along the ion flow.

含尘声的共振不稳定性

研究了离子定向流等离子体中尘埃声的不稳定性。当尘埃振荡的频率与离子振荡的频率一致时，这种不稳定性就会发展。得到了最不稳定振荡的特征频率和增长率。结果表明，在不稳定发展的非线性阶段，波的相互作用导致沿离子流形成拉长的尘团。

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.
