Enhancing stellarator accessibility through port size optimization
Nuclear FusionAccess to the plasma chamber in a stellarator reactor is essential for maintenance and diagnostics. However, the complex geometry of stellarator coils, often characterized by their strong twisting, can severely limit the space available for access ports.

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.

An optimized Hβ index for disentangling stellar population ages [PDF]
Monthly Notices of the Royal Astronomical Society, 2009 We have defined a new H_βabsorption index definition, H$_{β_o}$, which has been optimized as an age indicator for old and intermediate age stellar populations. Rather than using stellar spectra, we employed for this purpose a library of stellar population SEDs of different ages and metallicities at moderately high spectral resolution.

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 ...

Combination of quasi-isodynamic and piecewise omnigenous magnetic fields
Nuclear FusionDue to their simultaneous optimization for radial and parallel neoclassical transport, quasi-isodynamic (QI) fields have been the main choice of stellarator magnetic configuration for most fusion reactor candidates in recent years.

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 ...
