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 …

Recent evidence points toward the microtearing mode (MTM) as an important fluctuation in
the H-mode pedestal for anomalous electron heat transport. A study of the instabilities in the …

In a series of discharges on the DIII-D tokamak, fast vertical plasma jogs are used to induce
current perturbations in the steep gradient region of the H-mode edge. These current …

This article presents a global reduced model for slab-like microtearing modes (MTMs) in the
H-mode pedestal, which reproduces distinctive features of experimentally observed …

In this work, we present first-of-their-kind nonlinear local gyrokinetic (GK) simulations of
electromagnetic turbulence at mid-radius in the burning plasma phase of the conceptual …

In this study, gyrokinetic simulations are used to study pedestal fluctuations for DIII-D
discharge 174082 using the GENE code. Nonlinear local simulations indicate that electron …

We report on a detailed study of magnetic fluctuations in the JET pedestal, employing basic
theoretical considerations, gyrokinetic simulations, and experimental fluctuation data to …

Internal magnetic fluctuation measurements are utilized to identify turbulence associated
with micro-tearing modes (MTM) in the DIII-D Edge-Localized-Mode (ELM)-y H-mode …

We report the observation of a set of coherent high frequency electromagnetic fluctuations
that leads to a turbulence induced self-regulating phenomenon in the DIII-D high bootstrap …

A new, comprehensive set of evidence reveals that Micro-Tearing Modes (MTMs) dominate
pedestal electron heat transport in an H-mode experiment in the DIII-D tokamak. The …
