Impurity convection reversal caused by edge localized turbulence for generating a stationary edge radiative layer in the HL-2A tokamak

Impurity convection reversal caused by edge localized turbulence for generating a stationary edge radiative layer in the HL-2A tokamak

The effect of impurity on edge turbulence was investigated on the HL-2A tokamak using neon supersonic molecular beam injection (SMBI). For the first time, a stationary radiative layer accompanied by edge localized turbulence (ELT) lasting more than 100 ms is observed at the edge region $\rho = 0.7\s...
