RF-Specific Tungsten Erosion and Global Transport in ITER under Neon Seeding
Atul Kumar, Dhyanjyoti Nath, Wouter Tierens +15
Ion cyclotron radio-frequency heating (ICRH) is a key auxiliary heating system in ITER, but high-power RF operation can enhance plasma-material interactions through rectified RF sh…
The power exhaust constrained SPARC separatrix operational space
B. Lomanowski, T. Eich, J. D. Lore +3
In this work we extrapolate the separatrix operational space (SepOS) projections to SPARC and introduce detachment access criteria, thus formulating the combined power exhaust cons…
Harnessing Toroidal Neutral Flows to Enhance Divertor Particle Exhaust
M. Moscheni, A. Herrmann, J. D. Lore +5
In 1991 Reiter et al. (1991 Plasma Phys. Control. Fusion 33 1579) considered the onerous exhaust requirements of ITER, and wrote: "The vacuum pumping problem of a fusion reactor wi…
Understanding Carbon Sourcing and Transport Originating from the Helicon Antenna Surfaces During High-Power Helicon Discharge in DIII-D Tokamak
A. Kumar, D. Nath, W. Tierens +11
The high-power helicon wave system in the DIII-D tokamak introduces new plasma--material interaction (PMI) challenges due to rectified RF sheath potentials forming near antenna str…
Integrated modeling of boron powder injection for real-time plasma-facing component conditioning
Florian Effenberg, Klaus Schmid, Federico Nespoli +6
An integrated modeling framework for investigating the application of solid boron powder injection for real-time surface conditioning of plasma-facing components in tokamak environ…
Conceptual Design of a Doppler Spectrometer for 10 m/s Cross-Field Flows in Tokamak Divertors
Keisuke Fujii, Ryuichi Sano, Tomohide Nakano +4
It has been theoretically predicted that the \ExB drift caused by the spontaneously generated potential in scrape-off-layers (SOLs) and divertors in tokamaks is of a similar size t…
Modeling of Particle Transport, Neutrals and Radiation in Magnetically-Confined Plasmas with Aurora
F. Sciortino, T. Odstrčil, A. Cavallaro +8
We present Aurora, an open-source package for particle transport, neutrals and radiation modeling in magnetic confinement fusion plasmas. Aurora's modern multi-language interface e…
Predictive Modeling of a Lithium Vapor Box Divertor in NSTX-U using SOLPS-ITER
E. D. Emdee, R. J. Goldston, J. D Lore +1
The lithium vapor box divertor aims to detach the divertor plasma via evaporating and condensing lithium surfaces. By evaporating lithium near or at the divertor plate and condensi…
