Isotope mass dependence of pedestal transport in JET H-mode plasmas

open access: yesNuclear Fusion, 2023
We present a comparative transport analysis of the isotope mass dependence in the pedestal of two pairs of deuterium/hydrogen type I ELMy H-mode discharges in JET with ITER-like wall, one characterized by the same input power, the other one by the same ...

Modelling of the effect of ELMs on fuel retention at the bulk W divertor of JET [PDF]

open access: yes, 2019
Effect of ELMs on fuel retention at the bulk W target of JET ITER-Like Wall was studied with multi-scale calculations. Plasma input parameters were taken from ELMy H-mode plasma experiment.

N=2 ICRH of H majority plasmas in JET-ILW [PDF]

open access: yesAIP Conference Proceedings, 2015
Heating single ion species plasmas with ICRF is a challenging task: Fundamental ion cyclotron heating (w = wci) suffers from the adverse polarization of the RF electric fields near the majority cyclotron resonance while second harmonic heating (w = 2wci) typically requires pre-heating of the plasma ions to become efficient.

The Role of Combined ICRF and NBI Heating in JET Hybrid Plasmas in Quest for High D-T Fusion Yield

open access: yesEPJ Web of Conferences, 2017
Combined ICRF and NBI heating played a key role in achieving the world-record fusion yield in the first deuterium-tritium campaign at the JET tokamak in 1997.

Pedestal evolution physics in low triangularity JET tokamak discharges with ITER-like wall [PDF]

open access: yes, 2018
The pressure gradient of the high confinement pedestal region at the edge of tokamak plasmas rapidly collapses during plasma eruptions called edge localised modes (ELMs), and then re-builds over a longer time scale before the next ELM.

Quartz micro-balance results of pulse-resolved erosion/deposition in the JET-ILW divertor

open access: yesNuclear Materials and Energy, 2017
A set of quartz crystal microbalances (QMB) was used at JET with full carbon wall to monitor mass erosion/deposition rates in the remote areas of the divertor.

Investigation of deuterium trapping and release in the JET ITER-like wall divertor using TDS and TMAP

open access: yesNuclear Materials and Energy, 2019
Selected set of samples from JET ITER-Like Wall (JET-ILW) divertor tiles exposed both in 2013–2014 and 2011–2014 has been analysed using Thermal Desorption Spectrometry (TDS).

Recent progress in the quantitative validation of JOREK simulations of ELMs in JET [PDF]

open access: yes, 2017
Future devices like JT-60SA, ITER and DEMO require quantitative predictions of pedestal density and temperature levels, as well as inter-ELM and ELM divertor heat fluxes, in order to improve global confinement capabilities while preventing divertor ...

Comparison of OEDGE and EDGE2D‐EIRENE predictions of the scrape‐off layer conditions for attached plasmas

open access: yesContributions to Plasma Physics, Volume 64, Issue 7-8, August-September 2024.
Abstract Predictions of the scrape‐off layer (SOL) plasma conditions from the 2D multi‐fluid code EDGE2D‐EIRENE are compared to the OEDGE 1D fluid code for JET low‐confinement mode (L‐mode) plasmas. In the low‐recycling divertor conditions (divertor target plasma collisionality νe≈30$$ {\nu}_e\approx 30 $$), OEDGE and EDGE2D‐EIRENE agree on the ...
