Fast Ions in Mode Conversion Heating (3He)-H Plasmas in JET

Fast ions were analysed in experiments focusing on fundamental 3He minority and mode conversion ICRF heating in H plasmas and on 2nd harmonic heating of 3He ions at 2.65T mimicking D-T plasma heating in ITER at half its nominal toroidal magnetic field. Gamma-ray spectrometry, neutral particle analysers and fast-ion lost diagnostics provided information on the generation of fast-ion populations and on the distribution of ICRH power among the species in various heating scenarios and for a large range of 3He concentrations.
