Anomalous Stability
TECHNOLOGY General HISTORICAL // R&D
01 Executive_Summary
A landmark discovery made during LANL's FRX-A and FRX-B experiments (c. 1979-1981). The FRC plasma was found to remain stable for up to 60 µs—nearly one hundred times longer than predicted by ideal Magnetohydrodynamic (MHD) theory. This proved that kinetic effects (large ion orbits) provide natural stability to the FRC, establishing it as a viable confinement vessel.
