N2 - On GAMMA10, waves in Ion-Cyclotron Range of Frequency (ICRF) are used to produce initial plasmas, heat plasmas and keep magneto-hydrodynamic (MHD) stability. High performance plasmas in the minimum- B configuration supply MHD stability. In order to enhance plasma heating, we introduce an ICRF system for heating plasmas in the anchor cell and evaluate its antenna loading. Changing the antenna shape is expected to improve antenna loading. In the experiment, we confirm to increase the antenna loading by changing the antenna shape from simple bar-type to the double elliptic arc type.
