  The Sungkyunkwan University has developed the 9 MeV cyclotron for producing radio isotopes. In order to operate the cyclotron stably, all sub-systems in the cyclotron are controlled and monitored consistently. Therefore, each sub-system includes control devices, which is developed based on PLC, or DSP chip and the sub control modules interface with main control system in real time. As main control system, we choose the CompactRIO system from NI (National Instrument) to take into account the latency and robust control. The control system has high-performance processor running real-time OS, so that the system can control the cyclotron fast and exactly. In addition, the system can be remotely accessed over the network to monitor the status of cyclotron easily. The configuration of control system for 9 MeV cyclotron and performance test result will be described in this paper.

  This paper presents the magnet power supply (MPS) for the beam correction magnet. The required current to energize the magnet was ±20 A. The MPS has been implemented using the digital signal processing technology and shows the high stability and other good responses. The stability of the MPS was about ~10 ppm in short and long term, respectively. Various experimental results such as stability, bandwidth and simulation are given in this paper
