Ideal MHD theory of low-frequency Alfven waves in the H-1 Heliac [PDF]

, 2012
A part analytical, part numerical ideal MHD analysis of low-frequency Alfven wave physics in the H-1 stellarator is given. The three-dimensional, compressible ideal spectrum for H-1 is presented and it is found that despite the low beta (approx.

Exploration of the parameter space of piecewise omnigenous stellarator magnetic fields

Nuclear Fusion
Piecewise omnigenous fields are stellarator magnetic fields that are optimized with respect to radial neoclassical transport thanks to a second adiabatic invariant that is piecewisely constant on the flux-surface.

Study of Alfvén eigenmode stability in Quasi-Poloidal Stellarator (QPS) plasma using a Landau closure model

Nuclear Fusion, 2023
The aim of this study is to analyze the linear stability of Alfvén eigenmodes (AE) in the QPS device heated by a tangential neutral beam injector (NBI). The analysis is performed using the gyro-fluid code FAR3d, that solves the reduced MHD equations for ...

Fast and Invertible Simplicial Approximation of Magnetic‐Following Interpolation for Visualizing Fusion Plasma Simulation Data

Computer Graphics Forum, Volume 44, Issue 3, June 2025.
Abstract We introduce a fast and invertible approximation for fusion plasma simulation data represented as 2D planar meshes with connectivities approximating magnetic field lines along the toroidal dimension in deformed 3D toroidal spaces. Scientific variables (e.g., density and temperature) in these fusion data are interpolated following a complex ...

Quasi-Isodynamic Stellarators with Low Turbulence as Fusion Reactor Candidates

PRX Energy
The stellarator is a type of fusion energy device that—if properly designed—could provide clean, safe, and abundant energy to the grid. To generate this energy, a stellarator must keep a hot mixture of charged particles (known as a plasma) sufficiently ...

Formation of a Boron‐Oxide Termination for the (100) Diamond Surface

Advanced Materials Interfaces, Volume 11, Issue 33, November 25, 2024.
A boron‐oxide termination for (100) diamond is formed under ultrahigh vacuum conditions. This is the first demonstration of a new method of introducing a boron‐based species to the diamond lattice. This result has potential for enabling new surface‐based pathways to the fabrication of high quality boron‐doped delta layers and boron‐based material ...

Methods for Color Center Preserving Hydrogen‐Termination of Diamond

Advanced Materials Interfaces, Volume 11, Issue 24, August 23, 2024.
Hydrogen‐termination of diamond by three methods. Hydrogen plasma exposure with stage heating above 700 °C yields maximal coverage but causes irr loss of shallow nitrogen‐vacancy fluorescence. Plasma exposure without heating preserves nitrogen‐vacancies at the expense of increased oxygen coverage.
