Recent H majority inverted radio frequency heating scheme experiments in JET-ILW

EPJ Web of Conferences, 2017
Inverted 3He and D ion cyclotron minority heating scenarios were recently tested in JET-ILW. They confirm the good heating efficiency at low concentrations of ∼3%. The 3He minority heating scheme is only modestly affected by the change from a carbon (JET-

EDGE2D-EIRENE simulations of the impact of poloidal flux expansion on the radiative divertor performance in JET

Nuclear Materials and Energy, 2017
In the past at JET, with the MkI divertor, a systematic study of the influence of X-point height and poloidal flux expansion has been conducted [1,2] showing minor differences in the radiation distribution, whereas in [3] experiment and simulations have ...

Impact of ICRF on the scrape-off layer and on plasma wall interactions: From present experiments to fusion reactor

Nuclear Materials and Energy, 2019
Recent achievements in studies of the effects of ICRF (Ion Cyclotron Range of Frequencies) power on the SOL (Scrape-Off Layer) and PWI (Plasma Wall Interactions) in ASDEX Upgrade (AUG), Alcator C-Mod, and JET-ILW are reviewed.

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

Nuclear 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 ...

ITER-like current ramps in JET with ILW: experiments, modelling and consequences for ITER [PDF]

, 2015
Since the ITER-like wall in JET (JET-ILW) came into operation, dedicated ITER-like plasma current (I-p) ramp-up (RU) and ramp-down (RD) experiments have been performed and matched to similar discharges with the carbon wall (JET-C).

A study of the atomic and molecular power loss terms in EDGE2D-EIRENE simulations of JET ITER-like wall L-mode discharges

Nuclear Materials and Energy, 2017
A discrepancy in the divertor radiated powers between EDGE2D-EIRENE simulations and JET-ILW experiments employing a set of NBI-heated L-mode discharges with step-wise density variation is investigated.
