Dynamics of microscopic charged dust particles in cryogenic condition is studied experimentally. Dust particles were free falling through the liquid helium (LHe) vapor as well as through LHe. In the liquid, particles start to go up toward the surface. It was found that dust particles are charged negatively in vapor plasma, but lose the negative charge and became charged positively in the liquid, which is confirmed by the examination of the particle dynamics. Based on dust trajectories observed, the charge values for the dust particles were calculated.

“…Complex plasmas under extreme conditions [1], particularly under the ultra-cold conditions [2][3][4][5], are studied, since they provide an opportunity to investigate unusual charge systems. In particular, 2D complex (dusty) plasma structures, which can be formed by charged dust grains, located on the surface of liquid helium (LHe) [6].…”

“…Unfortunately, the nature of these remarkable features is still almost unclear mostly because of the lack of reliable experimental data. As it was obtained in numerical simulations (see, for example, [3]), at cryogenic temperatures of the discharge tube walls strong anisotropy of ion velocity distribution function takes place, which in turn can cause considerable change of structure and dynamic properties of a dusty plasma.…”

“…complex plasmas in cryogenic discharges, have received increasing interest over the last decade [1][2][3][4][5][6][7][8][9][10][11][12]. The interest has been largely motivated by extremely low temperature conditions (to several Kelvins) at those dust structures can exhibit unique structure properties such as very high dust concentration, the formation of compact dust spheres, etc.…”

Plasma Phys. 56, No. 3-4, 296 -301 (2016) Key words Dusty plasma, gas discharge, cryogenic temperatures, binary systems.Complex (dusty) plasmas of micron-sized CeO2 polydisperse particles in dc glow discharges at 77 and ∼10 K were experimentally investigated. It was obtained that dust structure in cryogenic gas discharge plasma can be a mixture of two fractions (components) with completely different dust ordering and dynamics. We observed under some specific conditions that fast-moving particles of one component diffuse through another component consisted of dust particles arranged in linear chains (strings). From experimental data analysis particle velocity distribution functions for each dust component were obtained. The possible nature of two-component dust structure formation was discussed.

“…Liquid and cooled dense helium was recently reported to be the working medium for modern detectors of elementary particles [4]. Finally, early in 1980s a keen interest arose in electric dis charges in liquid helium doped with dusty, which would allow a greater insight into the physics of cryo genic dusty plasmas [5][6][7].…”

The kinetic Boltzmann equation is applied to determine the electron energy distribution function in condensed helium over a wide range of pressures and temperatures. Account is taken of all the effects influ encing the electron kinetics in dense media. The electron multiplication rates and basic electron transport coefficients in condensed helium at atmospheric and elevated pressures have been determined. Starting from the streamer theory, the limiting breakdown characteristics of condensed helium are calculated. The theoret ical findings are compared with available experimental data. For liquid helium the long standing fundamen tal problem is first solved of the intrinsic dielectric strength determined exclusively by the electron processes in a liquid itself rather than in gaseous bubbles formed at the prebreakdown stage. Comparison with experi mental data allows also answering the question of how the voltage application duration and contaminants affect the breakdown characteristics of liquid helium.
