Discovery of Density Limit Disruption Induced by Core-localized Alfvnic Ion Temperature Gradient Instabilities in a Tokamak Plasma
Wei Chen, Liwen Hu, Jianqiang Xu +17
To achieve a high energy gain, the fusion reactor plasma must reach a very high density. However, the tokamak plasmas ofen undergo disruption when the density exceeds the Greenwald…
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…
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…
Development of a New Gas Puff Imaging Diagnostic on the HL-2A Tokamak
B. Yuan, M. Xu, Y. Yu +14
A new gas puff imaging (GPI) diagnostic has been developed on the HL-2A tokamak to study two-dimensional plasma edge turbulence in poloidal vs. radial plane. During a discharge, ne…
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…
Observation of Toroidal Alfven Eigenmodes during Minor Disruptions in Ohmic Plasmas
Yangqing Liu, Yi Tan, Zhe Gao +7
Toroidal Alfven eigenmodes (TAEs) excited in purely ohmically heated plasmas without any auxiliary heating have been identified for the first time in the SUNIST spherical tokamak.…
