The importance of the classical channel in the impurity transport of optimized stellarators
S. Buller, A. Mollén, S. L. Newton +2
In toroidal magnetic confinement devices, such as tokamaks and stellarators, neoclassical transport is usually an order of magnitude larger than its classical counterpart. However,…

Impurity transport in a mixed-collisionality stellarator plasma
Per Helander, Sarah L. Newton, Albert Mollén +1
A potential threat to the performance of magnetically confined fusion plasmas is the problem of impurity accumulation, which causes the concentration of highly charged impurity ion…

Rotation and Neoclassical Ripple Transport in ITER
E. J. Paul, M. Landreman, F. M. Poli +3
Neoclassical transport in the presence of non-axisymmetric magnetic fields causes a toroidal torque known as neoclassical toroidal viscosity (NTV). The toroidal symmetry of ITER wi…
