RF-induced Pinch of Resonant 3He Minority Ions in JET

The RF-induced pinch of 3He minority ions has been observed in JET affecting the diamagnetic energy, the fast ion energy content, the sawtooth period, the Alfven eigenmode excitation and the γ-emission. Further, the γ-emission is consistent with RF-detrapping into co-current passing orbits. The results from the SELFO code are consistent with the observations.
