Abstract

The compact conventional six-period torsatron L-V with an aspect ratio of A = 3 has been considered as a starting point for further computational optimization of the collisionless confinement of the guiding center orbits of fusion α particles. The configurations obtained possess improved neoclassical transport together with an equilibrium β limit at a level of (β) ≈ 10%. The optimization of magnetohydrodynamic (MHD) stability and the coil design are underway.
