Implementation and validation of guiding centre approximation into ERO2.0

Contributions to Plasma Physics, Volume 62, Issue 5-6, June‐July 2022., 2022
Abstract The Monte‐Carlo code ERO2.0 uses full orbit resolution to follow impurity particles throughout the plasma volume to determine the local erosion and deposition fluxes on the plasma‐facing components of fusion devices in magnetic confinement fusion.

Core‐SOL simulations of high‐power JET‐ILW pulses fuelled with gas and/or with pellets

Contributions to Plasma Physics, Volume 62, Issue 5-6, June‐July 2022., 2022
Abstract Experimental analysis of two couples of pulses in the range of input power of 26–32 MW, shows that addition of pellet throughput to high gas dosing pulses does not modify the plasma energy, but leads to better conditions as far as the tungsten concentration and core radiation are concerned. Significantly decreasing the gas dosing with addition

ICRH options for JET-ILW DTE2 operation [PDF]

AIP Conference Proceedings, 2020
Ion cyclotron resonance heating (ICRH) plays an important role in high performance JET-ILW plasma discharges, both for keeping the heavy impurities away from the plasma centre as for increasing the core ion temperature to boost fusion performance. While the former is needed in all high-performance discharges for steady state operation, the latter will ...

In Vivo Cellular‐Level 3D Imaging of Peripheral Nerves Using a Dual‐Focusing Technique for Intra‐Neural Interface Implantation

Advanced Science, Volume 9, Issue 3, January 25, 2022., 2022
Optical coherence tomography‐based peripheral nerve imaging platform with a new depth of focus extension technique is reported. The microstructures of a rat sciatic nerve with a metal wire inserted are volumetrically visualized in vivo. It is expected that new possibilities for solving the chronic implantation problem of an intra‐neural interface will ...

Disruption of lateral hypothalamic calorie detection by a free choice high fat diet

The FASEB Journal, Volume 35, Issue 9, September 2021., 2021
Abstract During the last few decades, the consumption of low‐calorie sweeteners, as a substitute for caloric sweeteners, has sharply increased. Although research shows that caloric versus low‐calorie sweeteners can have differential effects on the brain, it is unknown which neuronal populations are responsible for detecting the difference between the ...

L-H transition studies in tritium and deuterium–tritium campaigns at JET with Be wall and W divertor

Nuclear Fusion, 2023
The recent deuterium–tritium campaign in JET-ILW (DTE2) has provided a unique opportunity to study the isotope dependence of the L-H power threshold in an ITER-like wall environment (Be wall and W divertor).

Pedestal structure and stability in JET-ILW and comparison with JET-C

, 2020
Kontrollerad termonukleär fusion erbjuder ett lovande koncept för säker och hållbar energiproduktion. Det finns dock fortfarande många frågor som ska undersökas på väg till en kommersiell fusionsreaktor. En viktig aspekt är väggmaterialet som innesluter det varma termonukleära plasmat.

EFD-C(13)03/09 Study of the Effect of the Outer-Strike Point Location on the Divertor Neutral Pressure in JET-ILW Using EDGE2D/EIRENE [PDF]

, 2013
During the first year of the JET-ILW operation, a substantial effort was devoted to the L-mode domain characterization with the newly installed ITER-Like Wall (ILW), consisting of a W divertor and a Be main chamber.
