Abstract：
With the space charge forces considered, simulations of the evolution of the beam bunch in the K70 AVF cyclotron, which is an injector of the K540 RIKEN Ring Cyclotron (RRC), are carried out. The result shows that the deformation of the bunch and the formation of beam halo also take place in a cyclotron. But the mechanism of the formation of the beam halo in a cyclotron is different from that in a linear accelerator.
