The interaction between ion beams and plasma is a fundamental and important physical process, plasma can effectively neutralize the current and charge of ion beam pulses as an ideal medium for its transmission and focusing. The analytical model of short heavy ion beam pulse in cold background plasma under external magnetic field is established. Combined with the experimental parameters, by 2.5D particle-in-cell numerical simulations, the entire transport process of heavy ion beam application strong magnetic fields in plasma is investigated. Our research results indicate that the interaction between short-pulse heavy ion beams and plasma generates a longitudinally induced magnetic field in the same direction as the external magnetic field. Moreover, the electron cyclotron electromagnetic waves of anti-parallel to local magnetic field are excited, and the excitation mechanism is mainly drift instability of electrons beam caused by the heavy ion beam.
