Impact of edge turbulence spreading on broadening the heat flux width with plasma approaching the density limit
T. Wu, P. H. Diamond, L. Nie +8
This paper investigates the impact of edge turbulence spreading on broadening the heat flux width in Ohmic-plasma approaching the density limit of the J-TEXT tokamak. At the plasma…
Experimental Evidence of Nonlinear Avalanche Dynamics of Energetic Particle Modes
L. M. Yu, F. Zonca, Z. Y. Qiu +17
Recent observations in HL-2A tokamak give new experimental evidences of energetic particle mode (EPM) avalanche. In a strong EPM burst, the mode structure propagates radially outwa…
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…
Alfvenic Ion Temperature Gradient Activities in a Weak Magnetic Shear Plasma
W. Chen, R. R. Ma, Y. Y. Li +15
We report the first experimental evidence of Alfvenic ion temperature gradient (AITG) modes in HL-2A Ohmic plasmas. A group of oscillations with kHz and is detect…
Cylindrical anisotropic dynamos
R. Avalos-Zuñiga, M. Xu, F. Stefani +2
We explore the influence of geometry variations on the structure and the time-dependence of the magnetic field that is induced by kinematic dynamos in a finite cylinder. Th…
Ambivalent effects of added layers on steady kinematic dynamos in cylindrical geometry: application to the VKS experiment
F. Stefani, M. Xu, G. Gerbeth +4
The intention of the ''von Karman sodium'' (VKS) experiment is to study the hydromagnetic dynamo effect in a highly turbulent and unconstrained flow. Much effort has been devoted t…
