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…

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…
