Energy balance in JET

Nuclear Materials and Energy, 2017
In this paper we discuss results from the study of the energy balance in JET based on calculated heating energies, radiated energy from bolometry and tile calorimetry. Recent data enables us to be more confident in the numbers used and to exclude certain

An overview of tritium retention in dust particles from the JET-ILW divertor

Physica Scripta, 2021
Tritium (T) retention characteristics in dust collected from the divertor in JET with ITER-like wall (JET-ILW) after the third campaign in 2015–2016 (ILW-3) have been examined in individual dust particles by combining radiography (tritium imaging plate ...

Overview of interpretive modelling of fusion performance in JET DTE2 discharges with TRANSP

Nuclear Fusion, 2023
In the paper we present an overview of interpretive modelling of a database of JET-ILW 2021 D-T discharges using the TRANSP code. The main aim is to assess our capability of computationally reproducing the fusion performance of various D-T plasma ...

The role of edge plasma parameters in H-mode density limit on the JET-ILW

Nuclear Fusion, 2021
A study of a dataset of JET H-mode plasma with the Be/W ITER-like wall (JET-ILW) shows that reaching the edge MHD ballooning limit leads to confinement degradation.

Detection of alpha heating in JET-ILW DT plasmas by a study of the electron temperature response to ICRH modulation

Nuclear Fusion
In the JET DTE2 campaign a new method was successfully tested to detect the heating of bulk electrons by α-particles, using the dynamic response of the electron temperature T e to the modulation of ion cyclotron resonance heating (ICRH).

Fuel retention and erosion-deposition on inner wall cladding tiles in JET-ILW

Physica Scripta, 2021
The morphology of beryllium coatings on the Inconel inner wall cladding tiles after JET-ILW campaigns was determined. The focus was on: (i) fuel retention and its share in the overall fuel inventory; (ii) the change of the layer structure and composition.

Spectroscopic investigation of N and Ne seeded induced detachment in JET ITER-like wall L-modes combining experiment and EDGE2D modeling

Nuclear Materials and Energy, 2019
Modeling and experimental investigation of the distribution of seeded impurities and their influence on divertor detachment in all-metal tokamaks is critical for developing reactor-scale exhaust scenarios. In this work, the degree and operating space for
