文摘In recent years, a new approach named the spherical tokamak or spherical torus （ST） in the magnetic fusion research has made remarkable progress, parallel to the tokamak development including the international thermonuclear experimental reactor （ITER） projectTM. In ST experiments, magnetohydrodynamics stable high beta value （the ratio of the plasma pressure to the toroidal magnetic pressure） up to 50% has been routinely obtained. The confinement scaling for ST, though being less-confident compared to the database of tokamaks, seems at least to be as good as the tokamak.
