An overview of the physics of intrinsic torque is presented, with special emphasis on the
phenomenology of intrinsic toroidal rotation in tokamaks, its theoretical understanding, and …

The object of this review is to summarize the achievements of research on the Alcator C-Mod
tokamak [Hutchinson et al., Phys. Plasmas 1, 1511 (1994) and Marmar, Fusion Sci. Technol …

The affordable, robust, compact (ARC) reactor is the product of a conceptual design study
aimed at reducing the size, cost, and complexity of a combined fusion nuclear science …

Edge-localized-modes (ELMs) are a ubiquitous feature of H-mode in tokamaks. When
gradients in the H-mode transport barrier grow to exceed the MHD stability limit the ELM …

An improved energy confinement regime, I-mode, is studied in Alcator C-Mod, a compact
high-field divertor tokamak using ion cyclotron range of frequencies (ICRFs) auxiliary …

Fusion performance in tokamaks hinges critically on the efficacy of the edge transport barrier
(ETB) in suppressing energy losses. The new concept of'fingerprints' is introduced to identify …

One of our grand challenges towards fusion energy is the achievement of a high-
performance plasma core coupled to a boundary solution. The high confinement mode (H …

Plasmas are created by heating gases through the absorption of ionizing radiation in the
visible through the ultraviolet part of the electromagnetic spectrum and through collisional …

High-resolution charge-exchange recombination spectroscopic measurements of B 5+ ions
have enabled the first spatially resolved calculations of the radial electric field (E r) in 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 …
