SPECTRE: A robust solver for 3D equilibria with arbitrary topology
E. Balkovic, J. Loizu, E. Lanti +6
We present SPECTRE, a new equilibrium code based on the Multi-Region relaxed MHD model for robustly calculating 3D equilibria with general magnetic topology, allowing for flux surf…

The properties of resistive MHD modes and unstable spectra in advanced tokamak regimes
M. Coste-Sarguet, J. P. Graves
Advanced tokamak regimes, featuring extended regions of low magnetic shear, are promising candidates for future fusion reactors but are also more prone to specific kinds of MHD ins…

Direct prediction of saturated neoclassical tearing modes in slab using an equilibrium approach
Erol Balkovic, Joaquim Loizu, Jonathan P. Graves +2
We demonstrate for the first time that the nonlinear saturation of neoclassical tearing modes (NTMs) can be found directly using a variational principle based on Taylor relaxation,…
