On How Avalanches Penetrate the SOL and Broaden Heat Loads
Y. Kosuga, R. Matsui, P. H. Diamond
Recent experiments reported a correlation between power law core temperature spectra and emission, suggesting that heat avalanches penetrate the SOL. This paper derives a thr…
Spontaneous Transport Barriers Quench Turbulent Resistivity in 2D MHD
Xiang Fan, P. H. Diamond, L. Chacón
This Letter identifies the physical mechanism for the quench of turbulent resistivity in 2D MHD. Without an imposed, ordered magnetic field, a multi-scale, blob-and-barrier structu…
Subcritical turbulence spreading and avalanche birth
R. A. Heinonen, P. H. Diamond
In confined plasmas, a localized fluctuation in a marginal or weakly damped region will propagate and generate an avalanche if it exceeds a threshold. In this letter, a new model f…
Studies of Reynolds Stress and the Turbulent Generation of Edge Poloidal Flows on the HL-@A Tokamak
Ting Long, P. H. Diamond, Min Xu +3
Several new results in the physics of edge poloidal flows, turbulent stresses and momentum transport are reported. These are based on experiments on the HL-2A tokamak. Significant…
Formation and Evolution of Target Patterns in Cahn-Hilliard Flows
Xiang Fan, P. H. Diamond, Luis Chacón
We study the evolution of the concentration field in a single eddy in the 2D Cahn-Hilliard system to better understand scalar mixing processes in that system. This study extends in…
Edge Shear Flows and Particle Transport near the Density Limit in the HL-2A Tokamak
R. Hong, G. R. Tynan, P. H. Diamond +7
Edge shear flow and its effect on regulating turbulent transport have long been suspected to play an important role in plasmas operating near the Greenwald density limit . I…
