Abstract

Mega ampere spherical tokamak (MAST) and the impact of low aspect ratio on tokamak physics are discussed. MAST is characterized by strong toroidicity, strong shaping and self fields, low magnetic field, high beta, and large plasma flow. MAST data have an important influence on scaling laws for confinement and H-mode threshold power, exerting strong leverage on the form of these scaling laws. Low aspect ratio plasmas are also an ideal testing ground for plasma instabilities.
