AB - The RIKEN Ring Cyclotron (RRC) has been in stable operation over 28 years, and has been used for supplying many types of heavy-ion beams for various experiments. Since 2007, it has also been used for supplying beams to the three Ring Cyclotrons at the Radioactive Isotope Beam Factory (RIBF). The RRC has three types of injectors: the AVF cyclotron for comparatively light ions, variable-frequency linac for heavy-ions (RILAC), and the RIKEN Heavy-ions Linac 2 (RILAC2) for using high-intensity very-heavy ions. The total operation time of the RRC is more than 4000 h/year. Recently, some problems caused by age-related deterioration have often been occurring in the RRC. Some main coils of sector magnets had a sign of layer short. Two Magnetic Deflection Channels and some electrodes of Electrostatic Deflection Channel were damaged by some beam-loss. Several leaks of vacuum have happened at a feed-through of trim coils in the E-sector, at a bellows between the Resonator No.2 and the S-sector magnet, and at some copper cooling water pipes in the Resonator No.1 and the Resonator No.2. These present statuses of the RRC are presented in this paper.
