Abstract

A study was performed on high confinement mode (H-mode) threshold and dynamics in the National Spherical Torus Experiment (NSTX). The H-modes in spherical torus (ST) exhibit differences compared with tokamaks because the edge magnetic topology of a ST differs from a conventional aspect ratio tokamak. It was found that the comparisons between good L-modes and H-modes show greater differences in the ion channel than the electron channel.
