About
UK fusion propulsion for deep space; direct fusion drive prototype tested.
HyperJet Fusion Corporation designs and builds coaxial plasma guns for plasma-jet-driven magneto-inertial fusion (PJMIF). This pulsed fusion approach merges dozens of supersonic plasma jets to form a spherically imploding plasma liner, compressing a magnetized fuel target to achieve fusion conditions. The technology aims to provide a lower-cost path to commercial fusion energy and high-thrust space propulsion.
The company is a key partner in the Plasma Liner Experiment (PLX) at Los Alamos National Laboratory, supported by the ARPA-E ALPHA program. HyperJet provides the high-momentum plasma guns required to form the spherical liner in the vacuum chamber.
F. Douglas Witherspoon founded the company in 2017 as a spin-out from HyperV Technologies. It is based in Chantilly, Virginia.
