Are ghost surfaces quadratic-flux-minimizing?
S. R. Hudson, R. L. Dewar
Two candidates for "almost-invariant" toroidal surfaces passing through magnetic islands, namely quadratic-flux-minimizing (QFMin) surfaces and ghost surfaces, use families of peri…
Configurational Effects on Alfvenic modes and Confinement in the H-1NF Heliac
B. D. Blackwell, D. G. Pretty, J. Howard +12
The flexible Heliac coil set of helical axis stellarator H-1 (R=1m, <r>~0.15-0.2 m) permits access to a wide range of magnetic configurations. Surprisingly, in the absence of any o…
Relaxed MHD states of a multiple region plasma
M. J. Hole, R. Mills, S. R. Hudson +1
We calculate the stability of a multiple relaxation region MHD (MRXMHD) plasma, or stepped-Beltrami plasma, using both variational and tearing mode treatments. The configuration st…
Magnetohydrodynamic Stability of Plasmas with Ideal and Relaxed Regions
R. L. Mills, M. J. Hole, R. L. Dewar
A unified energy principle approach is presented for analysing the magnetohydrodynamic (MHD) stability of plasmas consisting of multiple ideal and relaxed regions. By choosing an a…
