Progress in the design of a drift-optimized torsatron device

Progress on the design of a drift-optimized torsatron configuration is presented. Previous work developed two (unoptimized) coil torsatron coil sets - including vertical and solenoidal field coils for flexibility. Here, we present the results of optimizing these configurations for improved neoclassical confinement. The goal of this project is to design a drift-optimized torsatron device in order to blend the benefits of a natural divertor region provide by the torsatron coils with improved neoclassical confinement from drift-optimization. Equilibrium, transport and stability characteristics will be compared across the optimized configurations.
