Dependence of Characteristics of Helium Ion Diffusion and Drift in Own Gas on its Temperature

摘要

The gas discharge at a lower atom temperature has a number of features which can appear in experiments with dusty plasma. At cryogenic temperatures of gas-discharge tube walls, strong anisotropy of the velocity distribution function of ions takes place, which, in turn, can cause a significant change in dust structure properties. In this study, the dependences of helium ion drift characteristics in a dc uniform electric field on the temperature of own gas atoms are analyzed.
