IRCF heating of jet plasmas with the third harmonic deuterium resonance

摘要

Ion cyclotron range of frequencies(ICRF)heating experiments with the third har- monic deuterium resonance in the plasma centre have been carried out at JET. These experiments were the first to demonstrate third harmonic damping on initially Maxwellian plasmas. A record deuterium-deuterium(DD)fusion reaction rate for ICRF-only heating on JET was achieved. The discharge have been simulated with the PION code(a self-consistent calculation of the evolution of the distribution function and the ICRF power deposition).
