Turbulent impurity transport simulations in Wendelstein 7-X plasmas
J. M. García-Regaña, M. Barnes, I. Calvo +8
A study of turbulent impurity transport by means of quasilinear and nonlinear gyrokinetic simulations is presented for Wendelstein 7-X (W7-X). The calculations have been carried ou…

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,…

Collisional transport of impurities with flux-surface varying density in stellarators
S. Buller, H. M. Smith, P. Helander +3
High-Z impurities in magnetic confinement devices are prone to develop density variations on the flux-surface, which can significantly affect their transport. In this paper, we gen…
