The cyclotron is designed as the injector of the Heavy Ion Medical Machines (HIMMs) in Wuwei city and Lanzhou city, China. It provides 10 µA carbon ion beams to fulfill the accumulation requirement in the following synchrotron. Four picoammeters acquire the beam current signals gathered by the radial detectors; meanwhile, the beam time structure is measured with Field Programmable Gate Arrays and a real-time operating system. This paper introduces the mechanical design of the radial detectors and further provides the thermal structure analysis result of probe tips with and without water cooling. Moreover, the hardware and software architecture of the control system for this detector is described, including the motion control and data acquisition system, which can implement simultaneous acquisition of beam current data and position at more than 10 kS/s. At last, the laboratory test and acceptance scheme of both mechanical and control systems are listed, and the beam current and turn pattern measurement results at HIMMs are presented in this paper.
