Engineering Physics Annotation << Back Mesh Model for Measuring Micrometeoroid Velocities Telegin A.M., Voronov K.E., Shestakov D.A. In this paper, a brief review of known designs and methods for determining the velocity of high-speed microparticles is carried out and subsequently, a grid-based sensor design capable of determining the velocity vector is proposed. A model of microparticle charge pointing on the grids of the investigated sensor and a detailed derivation of the formulas of the components of the particle velocity vector are given. Various methods of recording signals from the sensor grids are proposed and the most economical method using only one charge amplifi er is selected. The calculated relation is given, which shows the infl uence of the distance between the grids, parameters of charged microparticles on the shape of the output signal from the measuring grid. The resulting sensor is planned to be used in conjunction with a dust-impact mass spectrometer system to investigate the elemental composition of high-velocity particles.
