Abstract

Doublet II is a noncircular cross-section toroidal device with three magnetic axes. Theoretical considerations show that confinement of plasma in a doublet device might be similar to that of a tokamak with a much stronger toroidal magnetic field. Experiments carried out in Doublet II verify this in that the plasmas are found to have densities, temperatures, $q$ values, and confinement properties close to those of comparable circular-cross-section tokamak plasmas.
