NASA/Navy Submarine Plasmoid Experiments

The NASA/Navy Submarine Plasmoid Experiments represent a specialized joint research initiative designed to observe, measure, and analyze high-energy electrical discharge phenomena within confined maritime environments. Conducted aboard operational diesel-electric submarines, the program focused on the formation and behavior of luminous plasmoids generated by heavy circuit breaker arc faults. Throughout the test series, researchers recorded approximately 40 discrete arc events. The resulting plasmoid structures measured several millimeters in diameter and demonstrated sustained lifespans of roughly 0.2 seconds in atmospheric conditions. Optical emission spectroscopy revealed spectral signatures heavily dominated by vaporized electrode materials—primarily copper and silver—intermixed with ambient atmospheric constituents, specifically oxygen and nitrogen. This empirical research provided vital baseline data on how high-current electrical switches generate self-contained, long-lived plasma structures, cross-referencing early toroidal plasma confinement dynamics observed during the Scylla I-C Theta Pinch Experiments and formalizing empirical methods later tracked in our institutional Network Graph.
