Abstract
By using a transport code combined with an ion Bernstein wave tokamak ray tracing code, a modelling code for the ion Bernstein wave heting has been developed. With this code, the ion Bernstein wave heating experiment on the JIPPT-II-U tokamak has been analysed. It is assumed that a resonance layer is formed by the third harmonic of deuterium-like ions, such as fully ionized carbon, and oxygen ions near the plasma centre. As wave absorption mechanisms, electron Landau damping, ion cyclotron harmonic damping, and collisional damping are considered. The characteristics of the ion Bernstein wave heating experiment, such as an increase in ion temperature, a strong dependence of the quality factor on the magnetic field strength and a dependence of the ion temperature increment on the input power are well reproduced.
