Super-bunch acceleration is a key concept in an induction synchrotron. In the induction synchrotron, super-bunches confined in the longitudinal direction by a pair of barrier voltages are accelerated with long induction step voltage pulses. Synchrotron oscillation of the super-bunch is notable, which consists of long drifting between the barriers and quick reflection in the barrier regions. This is apparently distinguished from that of the conventional RF bunch, which is the pendulum oscillation. This property has been supposed to bring about qualitatively different features in the head-tail instability of the super-bunch. Recently the head-tail instability of the super-bunch has been systematically examined. In this paper, the preliminary results of macro-particle simulations is reported.
