Computing MHD equilibria of stellarators with a flexible coordinate frame
Florian J. Hindenlang, Gabriel G. Plunk, Omar Maj
For the representation of axi-symmetric plasma configurations, it is natural to use cyl. coordinates (R,Z,), where is an independent coordinate. The same cyl. coordinates…
Back to the Figure-8 Stellarator
G. G. Plunk, M. Drevlak, E. Rodriguez +3
The first stellarator design was a simple tube of plasma twisted and closed on itself in the form of a figure-8. The line of such devices, however, was quickly ended over concerns…
Construction of an invertible mapping to boundary conforming coordinates for arbitrarily shaped toroidal domains
Robert Babin, Florian Hindenlang, Omar Maj +1
Boundary conforming coordinates are commonly used in plasma physics to describe the geometry of toroidal domains, for example, in three-dimensional magnetohydrodynamic equilibrium…
Constructing nested coordinates inside strongly shaped toroids using an action principle
Zeno Tecchiolli, Stuart Hudson, Joaquim Loizu +3
A new approach for constructing polar-like boundary-conforming coordinates inside a toroid with strongly shaped cross-sections is presented. A coordinate mapping is obtained throug…
