Experimental measurements of the SOL power decay length (λ q) estimated from analysis of
fully attached divertor heat load profiles from two tokamaks, JET and ASDEX Upgrade, are …

The H-mode is a confinement mode of toroidal plasmas, which may make the goals of fusion
possible—the development of a clean energy source at competitive electricity costs. The …

The paper is a review of investigations of the H-mode on ASDEX performed since its
discovery in 1982. The topics discussed are:(1) the development of the plasma profiles, with …

Combined theoretical and experimental work has resulted in the creation of a paradigm
which has allowed semi-quantitative understanding of the edge confinement improvement …

Local edge parameters on the ASDEX Upgrade tokamak are investigated at the L-mode to H-
mode transition, during phases with various types of edge-localized modes (ELMs), and at …

Poloidal and toroidal rotation of the main ions (He 2+) and the impurity ions (C 6+ and B 5+)
in H-mode helium plasmas have been measured via charge exchange recombination …

ABSTRACT A major scientific success story of magnetic fusion research in the past several
decades has been the theoretical development and experimental testing of the process of …

A bifurcation in the thermal confinement of tokamaks, which resembles the L‐to H‐mode
transition, is shown to follow from properties of edge turbulence recently derived by Biglari et …

Classical drifts offer potential explanations for a variety of physical phenomena such as
poloidal asymmetries, possible extra pinch or outward flow of plasma depending on the Bt …

The authors' data indicate that the L-mode to H-mode transition in the DIII-D tokamak is
associated with the sudden reduction in anomalous, fluctuation-connected transport across …
