QUATOS: A University-Scale Test of the Quasi-Toroidal Stellarator Concept

A university-scale concept exploration experiment is proposed to investigate the improved confinement properties of the quasi-toroidal stellarator. The experiment would investigate three issues germane to a larger proof-of-principle experiment: first, the improved neoclassical confinement through me...

Description
Summary:A university-scale concept exploration experiment is proposed to investigate the improved confinement properties of the quasi-toroidal stellarator. The experiment would investigate three issues germane to a larger proof-of-principle experiment: first, the improved neoclassical confinement through measurement of the ion temperature dependence on axisymmetry; second, the impact of internal currents on the stability of this configuration; and third, the effect of the reduced viscosity on plasma rotation and the formation of transport barriers.
