Infrared thermography system on DIII-D [PDF]

Review of Scientific Instruments, 1990
Six infrared cameras measure temperature changes on the protective graphite armor inside the DIII-D vacuum vessel. Simultaneous time-dependent temperature measurements are made on armor tiles located on the centerpost and divertor regions, and on both outboard limiters.

Experimental conditions to suppress edge localised modes by magnetic perturbations in the ASDEX Upgrade tokamak

, 2018
Access conditions for full suppression of Edge Localised Modes (ELMs) by Magnetic Perturbations (MP) in low density high confinement mode (H-mode) plasmas are studied in the ASDEX Upgrade tokamak.

Letter [PDF]

, 2009
The onset of type I edge localized modes (ELMs) is investigated on the DIII-D tokamak. A fast imaging camera is used with an integration time of 1 νs and a time between frames of about 15 νs continuously recording for a period of 1.3 s.

Disruption mitigation studies in DIII-D [PDF]

Physics of Plasmas, 1999
Data on the discharge behavior, thermal loads, halo currents, and runaway electrons have been obtained in disruptions on the DIII-D tokamak [J. L. Luxon and L. G. Davis, Fusion Technol. 8, 2A 441 (1985)]. These experiments have also evaluated techniques to mitigate the disruptions while minimizing runaway electron production.

Bacillus thuringiensis Cry4Ba Insecticidal ToxinExploits Leu⁶¹⁵ in Its C-Terminal Domain to Interact with a Target Receptor—Aedes aegypti Membrane-Bound Alkaline Phosphatase

Toxins, 2021
In addition to the receptor-binding domain (DII), the C-terminal domain (DIII) of three-domain Cry insecticidal δ-endotoxins from Bacillus thuringiensis has been implicated in target insect specificity, yet its precise mechanistic role remains unclear ...

Advanced tokamak physics in DIII-D [PDF]

Plasma Physics and Controlled Fusion, 2000
Advanced tokamaks seek to achieve a high bootstrap current fraction without sacrificing fusion power density or fusion gain. Good progress has been made towards the DIII-D research goal of demonstrating a high-β advanced tokamak plasma in steady state with a relaxed, fully non-inductive current profile and a bootstrap current fraction greater than 50%.

Advances in radiated power control at DIII-D

Nuclear Materials and Energy, 2019
Feedback control of radiated power from the lower divertor Prad, div, L has been implemented in the DIII-D Plasma Control System (PCS). A realtime sensor for Prad, div, L has been constructed from 12 foil bolometer channels which agrees with standard ...

Direct Gyrokinetic Comparison of Pedestal Transport in JET with Carbon and ITER-Like Walls [PDF]

, 2019
This paper compares the gyrokinetic instabilities and transport in two representative JET pedestals, one (pulse 78697) from the JET configuration with a carbon wall (C) and another (pulse 92432) from after the installation of JET's ITER-like Wall (ILW ...

Experiments on plasma detachment in a V-shaped slot divertor in the DIII-D tokamak

Nuclear Fusion
Experiments in DIII-D demonstrate that the upstream plasma density to detach an un-pumped slot divertor is similar for a V-shaped and a flat-end slot, despite significantly higher neutral pressure in the V-shaped slot and in contrast to SOLPS-ITER ...
