Impact of divertor plasma parameters on characteristics of current-convective turbulence under DIII-D-like detached conditions

Journal Article Stepanenko, A. A. ; Wang, H. Q. ; Krasheninnikov, S. I. - Physics of Plasmas

Recent observations of turbulence in plasma of a DIII-D inner divertor revealed the formation of poloidally localized fluctuations with frequencies in the low-kilohertz range, when the machine was operating in the fluctuating state of detachment. This phenomenon can be related to the onset of the current-convective instability (CCI). In this contribution, we use the basic physical model of the instability to simulate the saturated current-convective turbulence under the DIII-D-like detached conditions. Parameter scans of turbulence characteristics are performed. The spatial and temporal spectra of fluctuations are obtained and compared with the available experimental data. It is demonstrated that simulations aremore »« less

Physics of ultimate detachment of a tokamak divertor plasma

Journal Article Krasheninnikov, S. I. ; Kukushkin, A. S. - Journal of Plasma Physics

The basic physics of the processes playing the most important role in divertor plasma detachment is reviewed. The models used in the two-dimensional edge plasma transport codes that are widely used to address different issues of the edge plasma physics and to simulate the experimental data, as well as the numerical schemes and convergence issues, are described. The processes leading to ultimate divertor plasma detachment, the transition to and the stability of the detached regime, as well as the impact of the magnetic configuration and divertor geometry on detachment, are considered.

Current convective instability in detached divertor plasma

Journal Article Krasheninnikov, S. I. ; Smolyakov, A. I. - Physics of Plasmas

The asymmetry of inner and outer divertors, which cause the inner divertor to detach first, while the outer one is still attached, results in the large temperature difference between the vicinities of inner and outer targets and the onset of large electric potential drop through detached plasma of the inner divertor. A large potential drop along with the inhomogeneity of the resistivity of detached plasma across the divertor leg drives the current convective instability in the inner divertor and subsequent fluctuations of radiation loss similar to that observed in experiments. The estimates of the frequency of plasma parameter fluctuations duemore »« less
