Impact of error fields and error field correction on heat fluxes in SPARC
Nuclear FusionUsing a single toroidal array of coils to reduce the $m,n = 2,1$ resonant error field (EF) produced by the misalignment of the axisymmetric coils in SPARC can result in the enhancement of the local divertor heat fluxes. Managing high divertor heat fluxes

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 ...

Thermal‐Hydraulic Assessment of W7‐X Plasma Vessel Venting System in Case of 40 mm In‐Vessel LOCA
Science and Technology of Nuclear Installations, Volume 2015, Issue 1, 2015., 2015 This paper presents assessment of the capacity of W7‐X venting system in response to in‐vessel LOCA, rupture of 40 mm diameter pipe during operation mode “baking.” The integral analysis of the coolant release from the cooling system, pressurisation of PV, and response of the venting system is performed using RELAP5 code.

Symposium - International Astronomical Union, 1997 The last two decades have seen the emergence of a new field in stellar astrophysics, the study of stellar coronae mostly in X-ray domain. With the advent of soft X-ray imagery X-ray emission was found from many thousands of solar-like stars. I will summarize the most important findings of X-ray surveys of late type stars and put the results in the ...

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.

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.
