Paper Abstract

The forming of accelerating voltage and current pulses with the given parameters is one of the most significant problems for creating the high-efficiency generators founded on a virtual cathode triode. The experiments have shown, that the nonlinear elements of an electrical circuit influence on the growing slope, amplitude and pulse length. One of nonlinear elements is the radiating triode. The results of theoretical investigations of the emission influence on the virtual cathode impedance and the forming of voltage and current pulses in the circuit with a inductive energy accumulator and exploding wires have been presented in this work. A model has been elaborated, including the influence of the electromagnetic radiation emission on the impedance of virtual cathode triode. The numerical simulation of the transient processes in the electrical circuit has been carried out. The dependences of the voltage and current pulses parameters, the emission efficiency, beam geometry and resonance chamber have been received.
