Journal Article Guttenfelder, W. ; Battaglia, D. J. ; Belova, Elena ; ... - Nuclear Fusion

Here, the mission of the low aspect ratio spherical tokamak NSTX-U is to advance the physics basis and technical solutions required for optimizing the configuration of next-step steady-state tokamak fusion devices. NSTX-U will ultimately operate at up to 2 MA of plasma current and 1 T toroidal field on axis for 5 s, and has available up to 15 MW of neutral beam injection power at different tangency radii and 6 MW of high harmonic fast wave heating. With these capabilities NSTX-U will develop the physics understanding and control tools to ramp-up and sustain high performance fully non-inductive plasmas withmore »« less

Broadening of divertor heat flux profile with increasing number of ELM filaments in NSTX

Journal Article Ahn, J. -W. ; Maingi, R. ; Canik, J. M. ; ... - Nuclear Fusion

Edge localized modes (ELMs) represent a challenge to future fusion devices, owing to cyclical high peak heat fluxes on divertor plasma facing surfaces. One ameliorating factor has been that the heat flux characteristic profile width has been observed to broaden with the size of the ELM, as compared with the inter-ELM heat flux profile. In contrast, the heat flux profile has been observed to narrow during ELMs under certain conditions in NSTX. In this paper, we show that the ELM heat flux profile width increases with the number of filamentary striations observed, i.e. profile narrowing is observed with zero ormore »« less

M3D-C1 simulations of the plasma response to RMPs in NSTX-U single-null and snowflake divertor configurations

Journal Article Canal, G. P. ; Ferraro, N. M. ; Evans, T. E. ; ... - Nuclear Fusion

Non-axisymmetric control coils and the so-called snow ake divertor con guration are two potential solutions proposed to solve two separate outstanding issues on the path towards self-sustained burning plasma operations, namely the transient energy bursts caused by edge localized modes and the steady state heat exhaust problem. In a reactor, these two proposed solutions would have to operate simultaneously and it is, therefore, important to investigate their compatibility and to identify possible con icts that could prevent them from operating simultaneously. In this work, single- and two- uid resistive magnetohydrodynamic calculations are used to investigate the e ect of externallymore »« less

Predictive modeling of a lithium vapor box divertor in NSTX-U using SOLPS-ITER

Journal Article Emdee, E. D. ; Goldston, R. J. ; Lore, J. D. ; ... - Nuclear Materials and Energy

The unmitigated heat flux in attached operation of a fusion power plant is predicted to be destructive to any solid divertor surface. Detachment, whereby the plasma pressure drops significantly before reaching the divertor target thus greatly reducing the heat flux and sputtering, will be necessary to ensure adequate lifetime of plasma facing components (PFCs). 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 condensing it closer to the main chamber, a lithium vapor density gradient can be created. This density gradient tiesmore »« less
