National Spherical Torus Experiment (NSTX)
01 Executive_Summary
NSTX is a spherical tokamak at Princeton Plasma Physics Laboratory (PPPL) exploring low-aspect-ratio magnetic confinement. It is relevant to the compact-fusion lineage because spherical tori share the high-beta, compact-geometry philosophy with FRC/compact-toroid concepts.
