MODELLING OF THE POTENTIAL HOLE FOR SPATIAL RESTRICTION OF SCATTERING OF THE LOADED PARTICLES OF PLASMA IN THE ELECTROMAGNETIC FIELD

Work is devoted to development of model of the potential barrier, allowing considering elastic reflection of particles about plasmatron walls. The coaxial magneto plasma accelerator which is really used in practice is considered. In the accelerator change of speed and weight of a plasma clot depending on the coordinate, defined both power characteristics, and gas dynamic regularities of hypersonic jet currents in the cylindrical channel is investigated. The type of potential function and the force field, modeling spatial restriction of scattering of particles of plasma is presented. Dynamics of distribution of the loaded particles in an electromagnetic field is established, the balance of energy taking into account an erosion of walls of the channel is graphically presented. Adequacy of the developed model of the coaxial magneto plasma accelerator taking into account an erosion caused at distribution of particles on a low-frequency spiral is shown. Low-frequency spiral movement is presented as superposition of longitudinal and cross movements. The solution of the differential equations was carried out by a method Runge-Kutta with the fixed step.
