Optimization of energy confinement in the \(1/\nu \) regime for stellarators
For certain conditions the stellarator magnetic field can be originally obtained in the real space coordinates and there is no necessity in its transformation to magnetic coordinates. A procedure working in real space coordinates is presented for maximizing the plasma energy content, based on reducing the most unfavorable \(1/\nu\) neoclassical transport. Preliminary results for the heliac-type stellarator TJ-II are presented showing a configuration with almost twice the stored energy of the standard TJ-II configuration.
