01 Executive_Summary

LANL experiment for Plasma-Jet-Driven Magneto-Inertial Fusion (PJMIF). 3m diameter spherical chamber, 36 plasma guns, 0.25 MJ total stored energy, ~10 μs shots, densities up to 10^17 cm^-3. 36 supersonic plasma jets at ~50 km/s form argon liner that compresses magnetized target. Key innovation: 'tangled magnetic field' target does NOT suffer from MHD instabilities found in spheromaks or FRCs. Simulations show compression to >1 keV possible. Published in Physics of Plasmas (October 2024). Partners: HyperJet Fusion Corp, NearStar Fusion, UAH (Cassibry), Univ. of New Mexico. ARPA-E BETHE funded. Commercialization roadmap: industry day July 30, 2025. Key personnel: S.C. Hsu (LANL, former ARPA-E ALPHA director), F. Chu, S.J. Langendorf, A.L. LaJoie. Fundamentally different MTF approach — plasma jets instead of solid liners (FRCHX, MagLIF) or lasers (NIF).

02 Definition

An experiment using converging plasma jets to form a spherically converging liner for MTF/MIF. PLX succeeded FRCHX in the LANL FRC/MTF lineage.
