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.

Separating divertor closure effects on divertor detachment and pedestal shape in DIII-D

, 2020
Comparison between an open divertor and a more-closed divertor in DIII-D demonstrates detachment up to 40% lower pedestal density ( n e , ped) in the closed divertor due to a combination of dec...

Computational protein stability analysis of SCN1A missense variants reveals domain‐dependent stability patterns

Epilepsia Open, EarlyView.
Abstract Objective To determine whether computational protein‐stability predictions discriminate pathogenic from benign SCN1A missense variants, and to characterize the structural distribution of predicted destabilization among pathogenic variants. Methods On an AlphaFold3‐predicted Nav1.1 structure, FoldX, and Rosetta Cartesian ΔΔG were computed for a

Late INa as a Therapeutic Target: New Strategies, Computational Modelling, Drug Development, and Clinical Translation

Medicinal Research Reviews, EarlyView.
ABSTRACT The Nav1.5 channel, a major isoform of voltage‐gated sodium ion channel, is mainly found in ventricular cardiomyocytes, playing a key role in generating essential cardiac action potentials for normal heart rhythms. Mutations in Nav1.5 have been associated with severe heart conditions such as long QT syndrome, Brugada syndrome, cardiac ...

Impact of ionization and transport on pedestal density structure in DIII-D and Alcator C-Mod

Nuclear Fusion
This paper investigates the role of ionization on the pedestal structure using both measurements and modeling for H-mode plasmas on DIII-D and Alcator C-Mod to enhance our ability to predict pedestal behavior in future pilot plants.

13C surface characterization of midplane and crown collector probes on DIII-D

Nuclear Materials and Energy, 2023
A dual collector probe system has been implemented on DIII-D for scrape-off-layer (SOL) impurity transport studies. These experiments injected isotopically enriched methane (13CD4) and sampled the impurities from this extrinsic, primary source with ...

First experimental tests of a new small angle slot divertor on DIII-D

Nuclear Fusion, 2019
A new small angle slot (SAS) divertor concept has been developed to enhance neutral cooling across the divertor target by coupling a closed slot structure with appropriate target shaping.

W-band system-on-chip electron cyclotron emission imaging system on DIII-D.

Review of Scientific Instruments, 2020
Monolithic, millimeter-wave "system-on-chip" (SoC) technology has been employed in heterodyne receiver integrated circuit radiometers in a newly developed Electron Cyclotron Emission Imaging (ECEI) system on the DIII-D tokamak for 2D electron temperature

Gamma ray imager on the DIII-D tokamak

Review of Scientific Instruments, 2016
A gamma ray camera is built for the DIII-D tokamak [J. Luxon, Nucl. Fusion 42, 614 (2002)] that provides spatial localization and energy resolution of gamma flux by combining a lead pinhole camera with custom-built detectors and optimized viewing geometry.
