Numerical simulation of electromagnetic pulse formation processes of EMIR complex

Summary form only given. The converter unit of the EMIR complex is used for electromagnetic pulse of quasi-rectangular shape with the voltage of /spl sim/ 10MV, current of /spl sim/2.5-3 MA, duration of /spl sim/120 ns formation in the transmitting line, supplying energy to the matched load. The converter unit is based on a linear accelerator principle and consists of five serially connected inductors, based on short-circuited water radial lines. Inductors are powered with the current from DFCG-240-20. At a preset moment, the supply circuit is broken with the special breaking key. On the inductor output voltage pulse is formed and energy, accumulated in the line, is supplied to the vacuum wave line with magnetic self insulation. At serial inductors connection the output voltage is summed up. Mathematical problem definition of calculation of operation processes of EMIR complex forming system, bringing to the solution of two-dimensional Maxwell equations in the geometry close to the real one, is presented in the paper. DFCG operation is described with equivalent electrical circuit, breaking key is simulated by the area with varying conductivity. Calculation results, optimizing operation of the forming system, are presented. The influence of breaking key diversification operation on formed pulse parameters is studied. Calculations were made using RISC method, adapted to solution of the problem presented.
