Hybrid method for RF heating problem of mirror confinement machine

Summary form only given, as follows. Summary form only given. A RF code named ´hybrid´ for the heating problem of a mirror confinement machine is developed. The meaning of the hybrid is that the heating problem is solved partially by an analytic and partially by a numerical method without loss of generality. The vacuum region including an antenna current is dealt with using an analytic technique and the usual FDM for the plasma region. In this work we propose proper boundary conditions of the electric field on the axis of cylinder. We applied this method to solving the heating problem of HANBIT the mirror confinement machine located at the KBSI site. The dispersion characteristic is studied by calculating the antenna radiation resistance for variance of the external magnetic field strength and the plasma density. The heating and field profiles are also investigated for the given magnetic and density configurations. Finally we compare the heating characteristics of slot and double half turn antennas.
