Helicity Injected Spheromak Experiment (HISE)

The Helicity Injected Spheromak Experiment (HISE) is a research facility that explores plasma science by creating toroidal (doughnut-shaped) plasma configurations called spheromaks. Using magnetic fields, HISE injects helicity—a measure of the twist and linkage in magnetic field lines—into the plasma. This process maintains a stable, self-contained plasma without the need for continuous external magnetic support, aiming to understand how such plasmas could be used for efficient, compact fusion energy devices. HISE helps scientists study magnetic confinement and stability critical for developing future fusion power systems.
