放医研サイクロトロン(NIRS-930, HM-18)の現状報告　（2018）

The cyclotron facility at National Institute of Radiological Sciences (NIRS) consists of a NIRS-930 cyclotron (Thomson-CSF AVF-930, Kb=110 MeV and Kf=90 MeV) and a small cyclotron HM-18(Sumitomo- Heavy- IndustryHM-18, K=20 MeV). The NIRS-930 has been used for production of radionuclide. The other purposes of NIRS-930 were research of physics, developments of particle detectors in space, research of biology, and so on. The annual total operationtime of NIRS-930 in last year was 1634 hours. The HM-18, that is a fixed energy negative-ion accelerator, has been providing 18 MeV protons and 9 MeV deuterons in order to produce short-lived radio-pharmaceuticals for PositronEmission Tomography (PET). The annual total operation time of HM-18 in last year was 1547 hours
