As an injector cyclotron (IC), HIMM-IC can provide 6.8 MeV/10 eµA 12C⁵⁺ beam for the synchrotron. Nevertheless, in terms of better beam quality and operation efficiency, HIMM-IC design still has a lot of room for improvement. We used OPAL simulation program to complete the 3D multi-particle dynamics simulation of HIMM-IC including the space charge effect. And the results show that it is in good agreement with the actual experimental measurements.}}, }
