“…Experiments on the action of clouds of charged microparticles obtained from regolith on a stainless steel surface were carried out at the plasmachemical gyrotron stand (gyrotron power up to 400 kW, radiation frequency of 75 GHz) at the plasma physics department of the Prokhorov General Physics Institute of the Russian Academy of Sciences. The scheme of the experiment, the specially designed plasmachemical reactor, and the microwave and video diagnostics, were described in detail in [ 40 , 42 , 43 ].…”

“…In [ 42 ], it was shown that a cloud of microparticles is generated above the surface of powders whose chemical composition and size distribution of particles are similar to lunar regolith (with an addition of a small amount of metal powder). Experiments were carried out during the action on laboratory regolith (henceforth, we call such powder mixture created in the laboratory simply “regolith”) of gyrotron pulses with power up to 400 kW and duration up to 10 ms.…”

In this article, results are presented of experiments on depositing charged particles, which imitate the levitating dust on the Moon, on stainless steel. Ensembles of particles are created above the surface of laboratory regolith whose composition and particle size distribution imitate the dust that covers the Moon’s surface. Under the action of the gyrotron radiation on regolith, non-linear physical-chemical processes develop (breakdown, chain plasmachemical reactions, and particle scattering by the Coulomb mechanism), which lead to the appearance of a levitating cloud of particles. The simulation experiment is based on the similarity between the processes that develop in the laboratory experiments with regolith and the processes that occur on the Moon during its bombardment by micrometeorites. The effect of the levitating cloud on stainless steel plates is studied and it is shown that regolith particles in the shape of spheroids of different sizes are deposited on the surface of the plates. The dimensions of the deposited particles and the density of their placement depend on the quality of treatment of the plate surface. It is shown that the laboratory-produced dusty plasma can be used in simulation experiments to study the modification of surfaces of different materials for space technology.

Определение механизмов образования лунной пыли, исследование динамики и взаимодействия пылинок с плазмой и с поверхностью космических аппаратов являются актуальными, при этом существуют несколько теоретических моделей по исследованию формирования плазменно-пылевого слоя над поверхностью Луны.В статье представлен краткий обзор исследованиям, изучавшие динамику пылевых частиц в плазменном слое над поверхностью Луны. Построена вычислительная модель динамики пылевых частиц левитирующих над поверхностью Луны на основе метода молекулярной динамики. Определено распределение пылевых частиц по размерам. Рассматриваются физические условия -плотность реголита, размеры частиц, параметры (плотность, температура электронови ионов, скорость) солнечного ветра, характеризующие динамику пылевых частиц вблизи поверхности Луны. Зарядка пылевых частиц рассчитывался с учетом плотности электронов, ионов солнечного ветра и фотоэлектронов в приближении ограниченных орбит (OML). Построен график зависимости заряда пылевой частицы от времени. Процессы зарядки пылевых частиц в плазменной среде вблизи поверхности Луны могут привести к левитации и транспортировки пылевых частиц по поверхности Луны под действием гравитационного и электрического поля.Ключевые слова: Лунный реголит, плазменно-пылевой слой, левитация.
