Microtearing turbulence limiting the JET-ILW pedestal [PDF]

Nuclear Fusion, 2016
Abstract The first nonlinear gyrokinetic turbulence simulations that quantitatively reproduce experimental transport levels in an H-mode pedestal are reported. In the JET-ILW (ITER-like wall) pedestal, the bulk of the transport in the steep gradient region is caused by the turbulence driven by the microtearing mode (MTM).

Fusion Materials Development at Forschungszentrum Jülich

Advanced Engineering Materials, Volume 22, Issue 6, June 2020., 2020
In fusion material research, the focus has been twofold‐plasma facing and structural materials allowing to withstand the extreme conditions such as neutron bombardment and high heat fluxes. In this contribution, the background for the choice of tungsten as first wall material is given and the advanced materials developed at Forschungszentrum Jülich ...

Tritium retention characteristics in dust particles in JET with ITER-like wall

Nuclear Materials and Energy, 2018
A tritium imaging plate technique (TIPT) in combination with an electron-probe microscopic analysis (EPMA) were applied to examine tritium (T) retention characteristics in individual dust particles collected in the Joint European Torus with the ITER-like

Testing a prediction model for the H-mode density pedestal against JET-ILW pedestals

Nuclear Fusion, 2023
The neutral ionisation model proposed by Groebner et al (2002 Phys. Plasmas 9 2134) to determine the plasma density profile in the H-mode pedestal, is extended to include charge exchange processes in the pedestal stimulated by the ideas of Mahdavi et al (

Space Weather Challenge and Forecasting Implications of Rossby Waves

Space Weather, Volume 18, Issue 3, March 2020., 2020
Abstract Rossby waves arise in thin layers within fluid regions of stars and planets. These global wave‐like patterns occur due to the variation in Coriolis forces with latitude. In the past several years observational evidence has indicated that there are also Rossby waves in the Sun.

Isotope removal experiment in JET-ILW in view of T-removal after the 2nd DT campaign at JET

Physica Scripta, 2022
A sequence of fuel recovery methods was tested in JET, equipped with the ITER-like beryllium main chamber wall and tungsten divertor, to reduce the plasma deuterium concentration to less than 1% in preparation for operation with tritium.

Species Composition, Phenotypic and Genotypic Resistance Levels in Major Malaria Vectors in Teso North and Teso South Subcounties in Busia County, Western Kenya

Journal of Parasitology Research, Volume 2020, Issue 1, 2020., 2020
Introduction. Knockdown resistance (kdr) is strongly linked to pyrethroid insecticide resistance in Anopheles gambiae in Africa, which may have vital significance to the current increased use of pyrethroid‐treated bed net programmes. The study is aimed at determining species composition, levels of insecticide resistance, and knockdown patterns in ...
