Ion's Formation and Photo Issue at Interaction of High-Speed Dust Particles with Optical Glass

One of the factors influencing on a resource of open elements of designs of space vehicles, is micro meteoric particles and space dust influence. The installation is developed for experimental simulation of particle's influence in a range of weights and speed accordingly 10-13 - 10-14 g ton 1 - 12 km×s-1 on a surface of optical glass, allowing following problem saving: - Ion's formation and photo issue from a glass surface;- Definition of degradation of a surface and dependence of optical characteristics of glass on size of a stream of particles. The device containing the receiver of ions with a high transparency for particles, the photo electronic multiplier established from the party to blow is with that end in view developed. Forward of the ion's receiver two Faraday's cylinders for measurement charge and speed of a particle are established.As a source of particles the electrodynamics accelerator with an acceleration direction 0,8 MV was used. The exit of ions and photo issue as functions of parameters particles are experimentally investigated. By means of an electronic microscope the element structure of substance of a particle and glass on a structure of craters in investigated.
