MONKES: a fast neoclassical code for the evaluation of monoenergetic transport coefficients in stellarator plasmas

Nuclear Fusion
MONKES is a new neoclassical code for the evaluation of monoenergetic transport coefficients in stellarators. By means of a convergence study and benchmarks with other codes, it is shown that MONKES is accurate and efficient.

3D MHD simulations of stellarator plasmas with SPECYL and PIXIE3D codes

, 2015
Preliminary simulations of stellarator-like configurations with the nonlinear 3D MHD codes SPECYL and PIXIE3D are reported in this work. SPECYL [1] solves the zero-b visco-resistive MHD equations in cylindrical geometry, whereas PIXIE3D [2] can run in ...

Reduction of Islands in Full-pressure Stellarator Equilibria [PDF]

, 2001
The control of magnetic islands is a crucial issue in designing Stellarators. Islands are associated with resonant radial magnetic fields at rational rotational-transform surfaces and can lead to chaos and poor plasma confinement.

Evaluation of neoclassical transport in nearly quasi-isodynamic stellarator magnetic fields using MONKES

Nuclear Fusion
Stellarator magnetic fields that are perfectly optimized for neoclassical transport (with levels of radial neoclassical transport comparable to tokamaks) are called omnigenous.

Optimizing stellarators with hidden symmetry

Stellarators confine fusion plasmas using three-dimensional magnetic fields composed of nested toroidal magnetic surfaces. In generic stellarators, trapped particles can drift across these surfaces and degrade plasma confinement. Certain topological properties of the magnetic field strength can suppress these drifts.
