	A high temperature superconducting ECR ion source (HTS-ECR) using REBCO coils is under development in Research Center for Nuclear Physics(RCNP), Osaka University. REBCO tapes are the second-generation high temperature superconductor, which maintains a high critical current even being placed in a strong external magnetic field. Using this REBCO coils as electromagnets, the HTS-ECR was designed to operate at microwave frequencies of 2.45 GHz and 10 GHz, for the purpose of producing high intensity proton, deuteron and helium beams. In this work, the low-temperature performance test results of the REBCO coils will be presented. The coil system and plasma chamber designed for the HTS-ECR will also be discussed. Results yielded in this research will also be made the best use of the development of a skeleton cyclotron, a compact air-core cyclotron which is under development in RCNP, Osaka University.

	A 230 MeV superconducting AVF cyclotron SC230 is developed by Sumitomo Heavy Industries, Ltd. This is the world’s smallest isochronous cyclotron for proton therapy, and its weight is 65 tons, which is 0.3 times that of our previous cyclotron model. The size is reduced by generating high magnetic fields using NbTi supercon-ducting coils cooled without cryogen. In addition, this cyclotron features the maximum beam current >1 uA and low power consumption <200 kW. The beam-commissioning test started at the end of 2020, the first extracted beam was observed in July 2021, and the basic performance of the beam was measured. The processes and results of the beam commissioning are reported.
