	HIMM (Heavy Ion Medical Machine) is an accelerator complex designed by Institute of Modern Physics, CAS, which accelerates carbon ions to the energy 400 MeV/A for tumor therapy. The main accelerator of HIMM is a synchronous accelerator. As a special design, we use a cyclotron as the injector of the synchrontron. The cyclotron is a compact cyclotron to accelerate C¹²⁵⁺ ions to the energy 6.8 MeV/A, and the extracted beam intensity of the cyclotron is 10 eµA. For stability and simplicity operation, we use two identical permanent magnet ECR ion sources in the axial injection line, that the ion sources can interchange with each other rapidly with the same performance, and only one main exciting coil with no trim coils in the cyclotron magnet. Up to now, three cyclotrons have been accomplished, one of them was operated in Gansu Wuwei Tumor Hospital to treat more than six hundred cancer patients in the last two and a half years, the other one had been fully commissioned in Lanzhou Heavy Ion Hospital about two years ago. After a short introduction to the heavy ion cancer treatment facility development in China, this paper will present operation status of the cyclotrons for HIMM.

HIMM (Heavy Ion Medical Machine) is an accelerator complex designed by Institute of Modern Physics, CAS, which accelerates carbon ions to the energy 400 MeV/A for tumor therapy. The main accelerator of HIMM is a synchronous accelerator. As a special design, we use a cyclotron as the injector of the synchrontron. The cyclotron is a compact cyclotron to accelerate C¹²⁵⁺ ions to the energy 6.8 MeV/A, and the extracted beam intensity of the cyclotron is 10 eµA. For stability and simplicity operation, we use two identical permanent magnet ECR ion sources in the axial injection line, that the ion sources can interchange with each other rapidly with the same performance, and only one main exciting coil with no trim coils in the cyclotron magnet. Up to now, three cyclotrons have been accomplished, one of them was operated in Gansu Wuwei Tumor Hospital to treat more than six hundred cancer patients in the last two and a half years, the other one had been fully commissioned in Lanzhou Heavy Ion Hospital about two years ago. After a short introduction to the heavy ion cancer treatment facility development in China, this paper will present operation status of the cyclotrons for HIMM. Typical performance and on-line operation reliability will be discussed.
