In GAMMA 10, Alfvén-ion-cyclotron (AIC) waves are spontaneously excited because of the perpendicular ions heating with ion cyclotron range of frequency waves. High-energy ions are transported to axial direction with pitch angle scattering owing to the AIC waves. In the high-energy ion signal detected with a semiconductor detector, the fluctuations with the differential frequencies between discrete peaks of the AIC waves are clearly observed. Recently, a microwave reflectometer detected the AIC mode in the anchor cell. The high-energy ions signal in the axial direction also increases when the AIC mode is excited.
