The dynamic features of the low-intermediate--high-(L-I-H) confinement transitions on HL-2A tokamak are presented. Here we report discovery two types limit cycles (dubbed type-$Y$ and type-$J$), which show opposite temporal ordering between radial electric field turbulence intensity. In type-$Y$, appears first after an L-I transition, grows first, followed by localized field. contrast, leads type-$J$. turbulence-induced zonal flow pressure-gradient-induced drift play essential roles in...
In this paper, recent progress on experimental analysis and theoretical models for non-local transport (non-Fickian fluxes in real space) is reviewed. The non-locality the heat momentum observed plasma, departures from linear flux-gradient proportionality, externally triggered phenomena are described both L-mode improved-mode plasmas. Ongoing evaluation of 'fast front' 'intrinsically non-local' models, their success comparisons with data, discussed
Abstract Since the last IAEA Fusion Energy Conference in 2018, significant progress of experimental program HL-2A has been achieved on developing advanced plasma physics, edge localized mode (ELM) control physics and technology. Optimization confinement performed. In particular, high- β N H-mode plasmas exhibiting an internal transport barrier have obtained (normalized pressure reached up to 3). Injection impurity improved confinement. ELM using resonance magnetic perturbation or injection a...

By tailoring 3D divertor plasma footprint through edge magnetic topology change, load was broadly dispersed and thus sputtering were well...
