Application of automated and robotically deployed in situ X‐ray fluorescence analysis for nuclear waste management

Journal of Field Robotics, Volume 39, Issue 8, Page 1205-1217, December 2022., 2022
Abstract Laboratory and synchrotron X‐ray fluorescence (XRF) analysis has both served as mainstay rapid and quantitative elemental analysis techniques for decades, attaining parts per million sensitivities for the majority of elements. Formerly, XRF was the reserve of large X‐ray generating systems and national facilities.

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 ...

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

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 ...

ICRH for core impurity mitigation in JET-ILW [PDF]

AIP Conference Proceedings, 2015
Ion cyclotron resonance frequency (ICRF) heating has been an essential component in the development of high power H-mode scenarios in JET-ILW. The steps that were taken for the successful use of ICRF heating in terms of enhancing the power capabilities and optimizing the heating performance in view of core impurity mitigation in these experiments 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).
