On the non-existence of stepped-pressure equilibria far from symmetry

Autor: Qu, Z. S., Hudson, S. R., Dewar, R. L., Loizu, J., Hole, M. J.

The Stepped Pressure Equilibrium Code (SPEC) [Hudson et al., Phys. Plasmas 19, 112502 (2012)] has been successful in the construction of equilibria in 3D configurations that contain a mixture of flux surfaces, islands and chaotic magnetic field lines

Time-dependent relaxed magnetohydrodynamics -- inclusion of cross helicity constraint using phase-space action

Autor: Dewar, R. L., Burby, J. W., Qu, Z., Sato, N., Hole, M. J.

Publikováno v: Physics of Plasmas 27, 062504 (2020)

A new formulation of time-dependent Relaxed Magnetohydrodynamics (RxMHD) is derived variationally from Hamilton's Action Principle using microscopic conservation of mass, and macroscopic conservation of total magnetic helicity, cross helicity and ent

The Infinite Interface Limit of Multiple-Region Relaxed MHD

Autor: Dennis, G. R., Hudson, S. R., Dewar, R. L., Hole, M. J.

We show the stepped-pressure equilibria that are obtained from a generalization of Taylor relaxation known as multi-region, relaxed MHD (MRXMHD) are also generalizations of ideal MHD. We show this by proving that as the number of plasma regions becom
