  HIMM(Heavy Ion Medical Machine)is a synchrotron based accelerator for cancer therapy in Wuwei city, China. It is composed of 2 ion sources, LEBT, cyclotron, MEBT, a synchrotron, HEBT and therapy terminals. The commissioning of HIMM is completed .At present, electrical safety, electromagnetic compatibility and performance testing of medical devices have been passed, and now enters the clinical tests phase. The beam diagnositics(BD) devices for HIMM are designed and produced by IMP BD department .An overview of the integrated devices is presented, and the common beam parameters in the different parts of the accelerator facility are reviewed including intensity measurement, beam profile, emmitance, energy and so on with the related detectors such as the View Screen, Faraday Cup, Radial Detector, Multi-wires, Phase Probe, Wire Scanner, DCCT, ICT, BPM, Schottky, Slit, Beam Stopper, Beam Halo Monitor, Multi-channel Ionization Chamber. Additionally, the RF-KO for beam extraction, the strip foil with automatic control system as well as the detectors for terminal therapy are described.

  The cyclotron is designed as the injector of the Heavy Ion Medical Machine (HIMM) in Wuwei city, China. It provides 10 uA carbon beams to fulfill the requirement of the accumulation in the following syn-chrotron. The Radial detector is used to measure the beam current and beam turn motion in this Cyclotron. The beam current signal gathered by radial detector is acquired by four picoammeters, meanwhile the beam time structure is measured with FPGA and real time operating system. This paper introduces the design of radial detector, the motion control and data acquisition system for it of the cyclotron. Finally, the beam current and turn pattern measurement results at HIMM are presented in this paper.
