National Spherical Torus Experiment

The National Spherical Torus Experiment (NSTX) is a research facility at Princeton Plasma Physics Laboratory studying a type of fusion reactor design called a spherical tokamak. It uses powerful magnets to contain and heat a plasma—a super-hot, ionized gas—much like the Sun's core. The goal is to understand how to efficiently produce and sustain fusion energy, which could provide a virtually limitless, clean energy source. NSTX experiments explore magnetic configurations, plasma behavior, and stability, contributing valuable insights toward developing practical fusion power for future energy needs.
