Experimental investigation of explosive high power pulse source

Abstract

This paper describes the designs and experimental investigation of indirectly charged two stage helical explosive magnetic flux compression generator (MFCG), pulsed power conditioning system with explosive metal wire array opening switch and the combined experimental results of the two systems above. This MFCG can generate high current (115kA) on comparatively high inductance inductor (4.5μH). The length of current pulse (from zero to the biggest) on the inductor is about 10Ωs. Energy gain of the MFCG is greater than 30 times. Combined experiment of the two system shows that more than 25GW of high power pulse can be reached on 10Ω-load resistor, and width of the pulse is more than 150ns. The experiment shows that the systems of which we studied are very successful and practical in producing high power pulse for MFCG.
