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 …

This paper reviews current understanding of key physics elements that control the H-mode
pedestal structure, which exists at the boundary of magnetically confined plasmas. The …

Divertor heat flux data from infra red (IR) from various tokamaks in H-Mode regime show that
the power width, $\lambda_ {q} $, scales approximately like 1.6 (R/a) ρ s, pol. However, the …

In this paper, we present linear and nonlinear gyrokinetic analyses in the pedestal region of
two DIII-D ELMy H-mode discharges using the CGYRO code. The otherwise matched …

The efficient operation of a tokamak is limited by several constraints, such as the transition to
high confinement or the density limits occurring in both confinement regimes. These …

The search for scenarios in which tolerable power exhaust is combined with good
confinement must involve high separatrix densities. We present here the first infrared …

We show for JET and ASDEX Upgrade, based on Thomson-scattering measurements, a
clear correlation of the density limit of the tokamak H-mode high-confinement regime with …

The ITER design, and future reactor designs, depend on divertor'detachment,'whether
partial, pronounced or complete, to limit heat flux to plasma-facing components and to limit …

The formation of the equilibrium radial electric field (Er) has been studied experimentally at
ASDEX Upgrade (AUG) in L-modes of “favorable”(ion∇ B-drift toward primary X-point) and …

The quasi-continuous exhaust (QCE) regime, formerly known as either type-II ELM or small
ELM regime is studied in ASDEX Upgrade. The regime is a natural type-I ELM-free H-mode …
