摘要：

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 mu m 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.
