Enhancement of Mid-/High-Z Impurity Transport by Continuous Li-granule Dropping in a Stellarator Plasma
Daniel Medina-Roque, Isabel García-Cortés, Naoki Tamura +16
An enhancement of core impurity transport is observed in high-density plasmas of the stellarator LHD heated by neutral beam injection when continuous lithium (Li) granule dropping…
Simplicial Approximation of Deforming 3D Spaces for Visualizing Fusion Plasma Simulation Data
Congrong Ren, Hanqi Guo
We introduce a fast and invertible approximation for data simulated as 2D planar meshes with connectivities along the poloidal dimension in deforming 3D toroidal (donut-like) space…
Implementation of higher-order velocity mapping between marker particles and grid in the particle-in-cell code XGC
Albert Mollén, M. F. Adams, M. G. Knepley +2
The global total- gyrokinetic particle-in-cell code XGC, used to study transport in magnetic fusion plasmas, implements a continuum grid to perform the dissipative operations, s…
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…
