  Developments of injection systems for cyclotrons at Research Center for Nuclear Physics (RCNP) Osaka University have been carried recently in order to improve the high intense ions in MeV region. The additional glazer lens on axial injection of AVF cyclotron has been installed to expand the beam accectance of cyclotron. Additional buncher for the heavy ion injection like Xe beam which requires high voltage in comparison with proton case also has been installed. Extension of baffle slits on injection line of Ring Cyclotron also has been done to extend the flexibility of injection orbit. Modification of low energy beam transport (LEBT) from ion sources to AVF injection axis including the development of fast emittance monitors also has been carried. Each component works well.

  The Research Center for Nuclear Physics (RCNP) cyclotron facility is equipped with the K140 AVF cyclotron and K400 ring cyclotron. The cascade cyclotron system provides high quality beams for precise experiments in nuclear physics using the high resolution spectrograph Grand-RAIDEN. Recently secondarily produced DC muons has become available. Radio-isotope production is regularly carried out for fundamental research in nuclear chemistry and medicine. The upgrade program of the cyclotron facility was carried out to reduce deterioration of cyclotron equipment and to construct new beam lines for experiments using muons and high quality beams. A bending magnet using a high-temperature superconducting wire was developed for switching between two beam lines. Design of a new type of high-temperature superconducting compact AVF cyclotron is underway to promote targeted alpha-particle therapy.
