Stress-triggered atomic explosion of trapped hydrogen initiates crack nucleation
Liang Gao, Thomas Schwarz-Selinger, Martin Balden +6
Hydrogen embrittlement (HE) has persisted for more than a century as one of the most intractable problems in materials science. The prevailing view1 that diffusive H governs embrit…
Experimental Evidence for Increased Particle Fluxes Due to a Change in Transport at the Separatrix near Density Limits on Alcator C-Mod
M. A. Miller, J. W. Hughes, T. Eich +5
Experimental inferences of cross-field particle flux at the separatrix, , show rapid growth near H-mode and L-mode density limits at high magnetic field on…
Nonlinear generation of global zonal structures in gyrokinetic simulations of TCV and ASDEX Upgrade magnetic configurations
I. Novikau, A. Biancalani, A. Bottino +6
In tokamaks, turbulence is responsible not only for the anomalous transport of heat and particles from the core to the edge, which reduces heating efficiency, but also for the gene…
Determination of confinement regime boundaries via separatrix parameters on Alcator C-Mod based on a model for interchange-drift-Alfvén turbulence
M. A. Miller, J. W. Hughes, T. Eich +13
The separatrix operational space (SepOS) model [Eich \& Manz, \emph{Nuclear Fusion} (2021)] is shown to predict the L-H transition, the L-mode density limit, and the ideal MHD ball…
