This paper summarizes the physical principles behind the novel three-ion scenarios using
radio frequency waves in the ion cyclotron range of frequencies (ICRF). We discuss how to …

We describe a new technique for the efficient generation of high-energy ions with
electromagnetic ion cyclotron waves in multi-ion plasmas. The discussed 'three …

Experiments were carried out in the JET tokamak to determine the critical ion temperature
inverse gradient length (R/L Ti= R|∇ T i|/T i) for the onset of ion temperature gradient modes …

This paper is a broad overview and a summary of the recent progress achieved in Ion
Cyclotron Range of Frequency (ICRF) systems, experiments and modelling during the last …

High resolution neutron emission spectroscopy (NES) and gamma-ray spectroscopy (GRS)
measurements of fast ions in high power fusion plasmas are reviewed. NES is a well …

Dedicated experiments were conducted in mixed HD plasmas in JET to demonstrate the
efficiency of the 3-ion ICRF scenario for plasma heating, relying on injected fast NBI ions as …

Abstract Ion Cyclotron Range of Frequencies (ICRF) heating and Neutral Beam Injection
(NBI) can have synergy due to the acceleration of NBI beam ions by ICRF wave fields at …

This paper presents results of JET ITER-like wall L-mode experiments in hydrogen and
deuterium (D) plasmas, dedicated to the study of the isotope dependence of ion heat …

In the past years, one of the focal points of the JET experimental programme was on ion-
cyclotron resonance heating (ICRH) studies in view of the design and exploitation of the …

This paper discusses the extension of the 'three-ion'species ICRF technique for heating
mixture plasmas using fast injected NBI ions as resonant 'third'species. In this scenario the …
