A gas puff imaging diagnostic is used in the National Spherical Tokamak Experiment [M. Ono, et al., Nucl. Fusion 40, 557 (2000)] to study the edge turbulence and intermittency present during H-mode discharges. In the case of low power Ohmic H-modes t

Experiments in NSTX have now unambiguously demonstrated the coupling of toroidal plasmas produced by the method of transient Coaxial Helicity Injection (CHI) to inductive sustainment and ramp-up of the toroidal current. The coupled discharges have ra
