Abstract
In the GAMMA10 tandem mirror, a strong ion cyclotron range of frequency hea ting is performed. As a result of the heating, the Alfven ion cyclotron (AI C) modes are spontaneously excited due to the strong temperature anisotropy . The AIC modes in the GAMMA10 are excited as the axial eigenmodes and dete cted at the whole of the device. In the recent experiments, the clear stand ing wave structure is observed with the magnetic probe measurements. Charac teristics of the AIC modes and the measurement of the axial profile are pre sented. (C) 2001 American Institute of Physics.
