摘要

研究了由不同大小和物质密度的校准尘埃粒子组成的三维等离子体-尘埃形态。研究了分层辉光放电中结构形成的特征,以及它们在外部磁场中的形状和动态。从几种类型的粉末中获得了空间上分离的双重结构,它们填充了尘埃捕集器,位于不同的层相中。对于结构的每个部分,都获得了平均旋转速度作为磁场的函数。在旋转机制取决于粒度和离子阻力占主导地位的范围内,旋转速度是通过数值估算得出的,并考虑了沿层的参数变化。

Double Dust Structures in Different Stratum Phases in Moderate Magnetic Fields

Three-dimensional plasma-dust formations consisting of calibrated dust particles differing in sizes and material densities are studied. The characteristic features of the structures formation in stratified glow discharge were studied, as well as their shapes and dynamics in the external magnetic fields. From several types of powders, the spatially separated double structures were obtained, which filled the dust trap, being located in different stratum phases. For each part of the structure, the average rotational velocities were obtained as functions of the magnetic field. In the range, in which the rotation mechanism depends on the particle size and the ion drag force is dominant, the rotational velocity was numerically estimated with allowance for the parameters variation along the stratum.

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.
