“…We developed and constructed an accelerator [3,[6][7][8] of high speed particles, which allows to simulate impacts of micrometeorites with a size of 1 ÷ 10 um and speeds of 1-15 km / s with materials of spacecraft structures under laboratory conditions. Figure 1 shows a block diagram of a linear accelerator for simulation of micrometeorites, the path of which consists of an injector, linear electrostatic accelerator (LESA), linear electrodynamic accelerator (LEDA), three measuring lines and an experiment chamber.…”

“…This is why it is currently important to obtain flows and levitating clouds of charged dust similar to lunar dust under laboratory conditions [ 10 , 11 , 12 , 13 , 14 ] to conduct simulation experiments and testing of both materials and components of future space technology, including lunar habitats [ 15 , 16 ]. Such experiments are conducted using acceleration technology [ 17 , 18 , 19 , 20 ], electron beams [ 12 , 13 , 14 ] or electrostatic powder dispensers [ 21 ]. These and other techniques are applied to imitate micrometeorites and man-made particles in simulation experiments with spacecraft materials [ 22 , 23 , 24 ] and in dust mitigation tests [ 25 , 26 , 27 ].…”

Microwave Simulation Experiments on Regolith (Lunar Dust) Deposition on Stainless Steel

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.
