Abstract

In this study, an experimental investigation of the effects of dust particle selection was carried out, in which the type of plasma-forming gas was varied. Using working gases with different ionization potentials, plasma filters (plasma-dust traps) capable of holding dust particles from 3 to 6.3 µm in size were obtained. The correspondence between the main parameters of the discharge (the longitudinal field and the electron temperature) and the size of the levitated particles was obtained from the numerical estimates. From the results obtained in the study, it was possible to create plasma filters with specified and finely tuned particle parameters. This makes it possible to create dusty plasmas with particles of required sizes.

不同电离势惰性气体辉光放电条纹中粉尘颗粒的选择

实验研究了不同等离子体形成气体类型对尘埃粒子选择的影响。使用具有不同电离电位的工作气体，获得了能够容纳3至6.3 μ m大小的尘埃颗粒的等离子体过滤器(等离子体粉尘捕集器)。通过数值估计得到了放电主要参数(纵向场和电子温度)与悬浮粒子尺寸的对应关系。从研究中获得的结果来看，有可能创建具有指定和微调粒子参数的等离子体过滤器。这使得制造具有所需大小粒子的尘埃等离子体成为可能。

期刊介绍： High Temperature Materials and Processes offers an international publication forum for new ideas, insights and results related to high-temperature materials and processes in science and technology. The journal publishes original research papers and short communications addressing topics at the forefront of high-temperature materials research including processing of various materials at high temperatures. Occasionally, reviews of a specific topic are included. The journal also publishes special issues featuring ongoing research programs as well as symposia of high-temperature materials and processes, and other related research activities. Emphasis is placed on the multi-disciplinary nature of high-temperature materials and processes for various materials in a variety of states. Such a nature of the journal will help readers who wish to become acquainted with related subjects by obtaining information of various aspects of high-temperature materials research. The increasing spread of information on these subjects will also help to shed light on relevant topics of high-temperature materials and processes outside of readers’ own core specialties.
