A 50 MeV H− compact cyclotron (CYCIAE-50) as a proton irradiation facility is under construction at China Institute of Atomic Energy. The proton beam with the energy of 30 MeV to 50 MeV and the current of 10 uA will be extracted by a single stripping extraction system. In order to reduce the beam loss, the combination magnet is fixed inside the magnetism yoke. The positions of stripping points for the different extraction energy are calculated and the extracted beam trajectories after stripping foil are simulated in detail in this paper. The extracted beam distribution after stripping foil and the extracted beam characters will be studied in this paper. The beam parameters after extraction will be given by the extracting orbit simulation. The design on the whole stripping extraction system has been finished and will be presented in this paper.

A 50 MeV cyclotron (CYCIAE-50) is been building at China Institute of Atomic Energy. CYCIAE-50 is a compact H− cyclotron with the proton beam energy of 30 MeV to 50 MeV and the beam current of 10 uA. A multi-cusp H− ion source with the beam current of 3 mA will be used for this machine. The design on the injection and central region of CYCIAE-50 has been finished. The way of matching the beam from ion source to central region and the design of central region will be present in this paper. In addition, some significant problems in central region will be discussed, including radial alignment, axial focusing, longitudinal focusing and energy gain, etc.

A compact cyclotron is developed by Cyclotron Accelerator Research Center at China Institute of Atomic Energy (CIAE) to extract 14 MeV proton beam for medical radioisotopes production, so as to meet the market demands of early diagnosis of malignant tumors, cardiovascular and cerebrovascular diseases. Owing to the small size and limited space of small medical cyclotrons, critical requirements are imposed on magnetic field measurement. For this reason, a magnetic field measurement system, with high-precision and high-stability, suitable for small cyclotrons is adopted and then an efficient magnetic field shimming method is used, which greatly reduces the construction period. It provides a strong guarantee for the stable operation of medical small cyclotrons.
