Exploration of the parameter space of piecewise omnigenous stellarator magnetic fields
Nuclear FusionPiecewise 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.

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 ...

A framework for discrete optimization of stellarator coils
Nuclear FusionDesigning magnets for three-dimensional plasma confinement is a key task for advancing the stellarator as a fusion reactor concept. Stellarator magnets must produce an accurate field while leaving adequate room for other components and being reasonably ...
