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…
