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.

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 ...

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 ...

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 ...

Near-surface expansion of vacuum stellarator configurations

Nuclear Fusion
Stellarators are inherently steady-state and disruption-free. However, three-dimensional geometry significantly increases the complexity of both equilibrium calculation and configuration optimization.
