Pacific Fusion is pursuing pulsed magnetic fusion systems. Their approach is based on impedance-matched Marx generators which will be arrayed to provide the high current, short pulses needed to compress and heat fusion fuel. Their plans include an experiment which will demonstrate net facility gain before the development of electricity producing fusion energy systems.
