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

The role of ETG modes in JET–ILW pedestals with varying levels of power and fuelling

Nuclear Fusion, 2022
We present the results of GENE gyrokinetic calculations based on a series of JET–ITER-like-wall (ILW) type I ELMy H-mode discharges operating with similar experimental inputs but at different levels of power and gas fuelling.

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 ...

Effect of the isotope mass on pedestal structure, transport and stability in D, D/T and T plasmas at similar β N and gas rate in JET-ILW type I ELMy H-modes

Nuclear Fusion, 2023
The work describes the pedestal structure, transport and stability in an effective mass (A eff) scan from pure deuterium to pure tritium plasmas using a type I ELMy H-mode dataset in which key parameters that affect the pedestal behaviour (normalized ...

Characterisation of divertor detachment onset in JET-ILW hydrogen, deuterium, tritium and deuterium–tritium low-confinement mode plasmas

Nuclear Materials and Energy, 2023
Measurements of the ion currents to and plasma conditions at the low-field side (LFS) divertor target plate in low-confinement mode plasmas in the JET ITER-like wall materials configuration show that the core plasma density required to detach the LFS ...

Isotope physics of heat and particle transport with tritium in JET-ILW type-I ELMy H-mode plasmas

Nuclear Fusion, 2023
As part the DTE2 campaign in the JET tokamak, we conducted a parameter scan in T and D-T complementing existing pulses in H and D. For the different main ion masses, type-I ELMy H-modes at fixed plasma current and magnetic field can have the pedestal ...

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).
