Key specifications<\/strong><\/p>\n\n\n\n

The bench is a plasma gas-dynamic tunnel.The 100 m\u00b3\/s evacuation system of the bench and its cryopanels cooled with liquid nitrogen produce a static vacuum of 10-5 N\/m2\u00b2 in the work chamber, which is a nonmagnetic steel cylinder of diameter 1.2 m and length 3.5 m \u2014 with gas inleakage, the chamber pressure is 10-4<\/sup> \u2014 10-2<\/sup> N\/m2. Supersonic rarefied plasma flows are produced using a hot-cathode gas-discharge accelerator, whose working medium is ionized by electron impact and electron oscillation in an external magnetic field. The plasma flow parameters are measured using a system of electrical and pressure probes, 5.45 and 9.8 GHz interferometers, and a \u041c\u04257303 mass-spectrometer. The diagnostic instruments and models under study are placed on the movable platforms of the upper and lower coordinate tables with four degrees of freedom each. The positioning is checked using potentiometric pickups. The positioning accuracy is \u2014 0.5 \u00b7 10-3<\/sup> m for linear displacements and \u2014 0.5 \u00b0 for angular ones.<\/p>\n\n\n\n

Description<\/strong><\/p>\n\n\n\n

The plasmoelectrodynamic bench serves to study various aspects of interaction between a solid body (e.g. spacecraft materials and structural elements) with its environment in the Earth ionosphere and magnetosphere. The bench systems and capabilities allow one to simulate the interaction of the planets of the Solar System, artificial bodies, and spacecraft with the interplanetary medium (solar wind), cold ionospheric and hot magnetospheric plasma flows, charged-particle streams, electric and magnetic fields, and solar-spectrum and radar-range electromagnetic radiation in high-elliptical, geostationary, low, medium, and geopolar orbits at altitudes of 150 to 40,000 km.<\/p>\n\n\n\n

The plasmoelectrodynamic bench is the National Treasure according to the Cabinet of Ministers of Ukraine’s order #650 from 28\/08\/2013.<\/p>\n\n\n\n
