Description

Mode behaviors including non-linear development and pressure profiles during internal reconnection events are clarified in the MAST spherical tokamak. In a q0 > 1 discharge, the tearing mode is a trigger; however, non-linearity of modes is not confirmed. On the other hand, in a q0 < 1 discharge, the harmonics of a m/n=4/1 mode of ∼22 kHz are confirmed. Method for identification of poloidal mode in ST configuration is also given. (author)
