	We propose a separated sector cyclotron (SSC) using high temperature superconducting (HTS) magnet for a next generation cyclotron. From its stability and low operating cost, HTS cyclotrons are expected to apply for accelerator-driven subcritical reactors or beam cancer treatment systems. On the other hand, we still have a variety of issues and challenges to implement them. As a first step, we are planning to develop an HTS cyclotron as an injector for K400 ring cyclotron at RCNP. It will be the first attempt in the world. This plan will improve beam intensity in our facility and also contribute to component developments for the next generation cyclotron. The most serious issues are development of large-size HTS magnets that can be used in SSC. One-meter-size HTS dipole magnet is made for testing. Now we are going to exam the magnet and evaluate the characteristics of large HTS magnets. The result of the test will be incorporated with the sector magnet design. Moreover, we have been working on conceptual design of the new injector, developed magnetic field and orbit analysis programs. In this session, the current status of designing HTS injector cyclotron at RCNP will be discussed.

Developments of injection systems for cyclotrons at Research Center for Nuclear Physics (RCNP) Osaka University have been carried recently in order to improve the highly intense heavy ions in MeV region for the secondary RI beam, et al. The additional glazer lens on axial injection of AVF cyclotron is one of those and it has been installed for the purpose of increasing beam transmission to the inflector in center region of cyclotron. Another development is additional buncher for the heavy ion injection like Xe beam which requires high voltage in comparison with proton case.
