Explosive Pulsed Power for Controlled Fusion

Megaampere pulsed currents with a rise time of 0.1-1 μs are required for fusion studies. Use of one or several stages of the current pulse sharpening should be used at such pulses formation using inductive systems of energy storage. In this case large energy losses take place. According to estimations, to realize technical projects of fusion reaction ignition the inductive sources with the stored energy of tens and hundreds megajoules are required. In RFNC-VNIIEF during the last 30 years devices for fusion studies are based on the systems with explosive magnetic flux compression - explosive magnetic generators (EMG). In the paper we consider high-power disk EMG for EMIR complex, intended for soft x-ray radiation generation of 10-megajoule level. Also, the paper presents experimental results with electric - exploded and explosive current opening switches.
