Nuclear Physics: The SPARC tokamak in Devens, Massachusetts, has demonstrated a sustained plasma reaction producing more than twice the thermal energy input required to heat it, marking a historic engineering milestone for commercial magnetic confinement fusion.
20-Tesla High-Temperature Superconducting Magnets
SPARC utilizes rare-earth barium copper oxide (REBCO) superconducting tapes to produce a 20-tesla magnetic cage, confining 100-million-degree deuterium-tritium plasma in a device one-fortieth the volume of ITER.
Path to Commercial ARC Power Plants
Data from the successful burn phase validates the core physics models that will guide construction of ARC, a planned 400-megawatt grid-connected pilot fusion power plant.
