Abstract Spherical torii require non-inductive current drive for startup and steadystate sustainment. Coaxial Helicity Injection (CHI) is used to produce and sustain non-inductive discharges with over 200 kA toroidal plasma current in both the National Spherical Torus Experiment (NSTX, R = 0.85 m, a = 0.67 m, Bo = 0.3 T) at the Princeton Plasma Physics Laboratory and the Helicity Injected Torus experiment (HIT-II, R = 0.3 m, a = 0.2 m, Bo = 0.5 T) at the University of Washington.
