Abstract
The 1/ν neoclassical transport is computed for the standard, the drift-orbit-optimized and the quasi-axisymmetric versions of CHS. For the computations, a new method is used which is based on the integration along magnetic field lines. The calculations show the advantage of the quasi-axisymmetric CHS configuration over the standard configuration resulting in a reduced 1/ν transport. It is shown that also for the drift-orbit-optimized configuration the 1/ν transport is reduced; however, by a smaller amount than for the quasi-axisymmetric configuration.Keywords
