On the other hand, in high ion temperature aimed discharge ion cyclotron emissions (ICEs) are clearly detected using ion cyclotron heating antennas as a magnetic fluctuations, and the damped mechanism of ICEs is similar to that of HHFW. Observed magnetic fluctuations are rapidly increased after parallel NB is injected, and the excitation effect of ICEs seems to be different between fundamental and multi-harmonic ICEs in the direction of parallel NBI.
