Abstract:

This study was an experimental investigation of the feasibility of an explosive MHD pulsed electric power generator. The electrical energy, when reconverted into thermal energy with a large exploding wire, will yeild very high energy densities temperature 10 eV - 100 eV suitable for nuclear weapon simulation in large scale explosive field tests. The key technical problem was seen as fast 100 microsecond self-excitation of a low inductance field coil to full power field strength of about 50 tesla. Experimental results demonstrate MHD power production and partial self-excitation. Lower than expected electrical conductivity prevented complete self-excitation and full power operation. Achieved field amplification was 20 dB to 3.7 tesla instead of 43 dB 50 tesla required for full power. Achieved power was in excess of 200 megawatts. Recommendations for further work to resolve the conductivity problem or minimize its effect on the field amplification process are made. Author
