The ring trap 1 (RT-1) device is a "laboratory magnetosphere" created by a levitated superconducting ring magnet, which is dedicated to the study of plasma physics in the vicinity of a magnetic dipole. Electron cyclotron heating with 8.2 GHz and ~50 kW is used to produce the plasmas. The high energy electrons with a few ten keV are produced, but the ions still remain cold. Ion heating is expected to achieve a high beta and to change the aspect of plasma confinement theoretically. The ion cyclotron heating with 3 MHz and ~10 kW is being prepared in RT-1. The associate operation regime for electron cyclotron heating is surveyed to produce a target plasma. The ion cyclotron heating(ICH) is applied to the target plasma as an auxiliary heating. The preliminary result of ICH is presented with other diagnostic system.
