Princeton Fusion

ORGANISATION Fusion Physics Also: Princeton Fusion Systems, PFRC, Starfire reactor, Princeton Satellite Systems fusion

01 Executive_Summary

Princeton Fusion Systems (Plainsboro, NJ) — spun out of Princeton Plasma Physics Laboratory (PPPL). Developing the Princeton Field-Reversed Configuration (PFRC): 1-10 MW portable fusion reactors 'sized to fit on a truck' — same concept as the CFR. D-He3 fuel (aneutronic). FRC plasma geometry (same as CFR). RF heating (vs CFR's neutral beam injection). PFRC-1 (2006): 4-cm plasma radius. PFRC-2: electrons heated to >100 eV, plasma durations to 300 ms — 'more than 10^4 times longer than the predicted tilt instability growth time.' 'No new materials or superconducting coils needed.' '1-10 MW PFRC reactors would be suitable for diverse applications, from submarines to urban environments to space propulsion.' Government support: DARPA ERIS Marketplace 'Awardable' status for 'Starfire' fusion microreactor — 'Starfire would revolutionize off-grid power, military forward power, disaster relief, and space propulsion and power — all critical for advancing DoD missions.' ARPA-E GAMOW program for power electronics. Partnership with Pulsar Fusion (UK) for nuclear fusion propulsion. The PFRC is essentially the CFR concept by another name — FRC, truck-sized, military applications.
