Up to 15s H-mode plasmas with 8MW of ICRH power were executed on JET, with the
JET record high injected ICRH energy of 108MJ. The ICRH discharges, using the H minority
heating scheme at 3% minority concentration, were stationary without any major MHD
activities or impurity accumulation. NBI heated discharges were executed consecutively to
match the dimensionless plasma profiles of q, ?*, ?*, ?n and Ti/Te using the same shape. Both
pulses had gas puff modulation at 3Hz for the whole duration of the discharges to extract
perturbative particle transport coefficients. The ELM frequencies are 75Hz and 45Hz for the
ICRH and NBI pulses, respectively, with mixed ELMs and affected by gas puff modulation.
