SUNIST, the abbreviation of Sino-UNIted Spherical Tokamak, is a small spherical tokamak in the Department of Engineering Physics, Tsinghua University, Beijing, China.
Alfven wave current drive experiments in spherical tokamak plasmas
Alfven wave can generate toroidal plasma current without density limits. This is very favourable for spherical tokamak plasmas, which have very high dielectric constants that makes LHCD or ECCD very hard.
