Target Plasma Formation for Magnetic Compression/Magnetized Target Fusion

Experimental observations of plasma behavior in a novel plasma formation chamber are reported. Experimental results are in reasonable agreement with two-dimensional magnetohydrodynamic computations suggesting that the plasma could subsequently be adiabatically compressed by a magnetically driven pusher to yield 1 GJ of fusion energy. An explosively driven helical flux compression generator mated with a unique closing switch/opening switch combination delivered a 2.7 MA, 347 μs magnetization current and an additional 5 MA, 2.5 μs electrical pulse to the chamber. A hot plasma was produced and 10¹³ D-T fusion reactions were observed.
