Abstract

The stability of a planar plasma crystal in an external confining force field is investigated. Particles are assumed to be located in the plasma with Maxwellian electrons and with a directed flow of cold ions. It is shown that, together with the coupled wave instability, four more types of aperiodic instabilities arise, which lead to the formation of different structures. A region of the crystal stability in the space of external parameters is constructed.

平面等离子体晶体的稳定性

摘要

研究了平面等离子体晶体在外部约束力场中的稳定性。假定粒子位于具有麦克斯韦电子和定向冷离子流的等离子体中。结果表明，与耦合波不稳定性一起，还出现了另外四种非周期性的不稳定性，这导致形成不同的结构。构造了在外部参数空间中晶体稳定性的区域。
