Complex structure of turbulence across the ASDEX Upgrade pedestal

Journal of Plasma Physics, 2023
The theoretical investigation of relevant turbulent transport mechanisms in H-mode pedestals is a great scientific and numerical challenge. In this study, we address this challenge by global, nonlinear gyrokinetic simulations of a full pedestal up to the separatrix, supported by a detailed characterisation of gyrokinetic instabilities from just inside ...

Observation of confined current ribbon in JET plasmas [PDF]

, 2009
we report the identification of a localised current structure inside the JET plasma. It is a field aligned closed helical ribbon, carrying current in the same direction as the background current profile (co-current), rotating toroidally with the ion ...

The role of edge fueling in determining the pedestal density in high neutral opacity Alcator C-Mod experiments

Nuclear Materials and Energy, 2021
SOLPS-ITER modeling of EDA H-mode experiments on Alcator C-Mod find that the electron density pedestal structure is unaffected by increased gas fueling when approaching ITER-like opaqueness conditions.

Pedestal structure and energy confinement studies on TCV [PDF]

Plasma Physics and Controlled Fusion, 2018
High external gas injection rates are foreseen for future devices to reduce divertor heat loads and this can influence pedestal stability. Fusion yield has been estimated to vary as strongly as so an understanding of the underlying pedestal physics in the presence of additional fuelling and seeding is required.

Air-clad silicon pedestal structures for broadband mid-infrared microphotonics [PDF]

Optics Letters, 2013
Toward mid-infrared (mid-IR) silicon microphotonic circuits, we demonstrate broadband on-chip silicon structures, such as: (i) straight and bent waveguides and (ii) beam splitters, utilizing an air-clad pedestal configuration which eliminates the need for typical mid-IR-lossy oxide cladding.

Studies of the pedestal structure and inter-ELM pedestal evolution in JET with the ITER-like wall [PDF]

Nuclear Fusion, 2017
The pedestal structure of type I ELMy H-modes has been analysed for JET with the ITERlike Wall (JET-ILW). The electron pressure pedestal width is independent of ρ* and increases proportionally to √βpol,PED. Additional broadening of the width is observed, at constant βpol, PED, with increasing ν* and/or neutral gas injection and ...
