Abstract The RCNP facility consisting of the AVF-Ring cyclotron cascade and high-resolution experimental apparatuses has advanced the high-precision frontier of nuclear physics in the range of intermediate energies up to 416 MeV for pro-tons. The best performance of the cyclotron beam has rexently been realized in a long term over a week as the highly sta-bilized operation of the Ring Cyclotron without any tuning of cyclotron parameters. This very stable high-resolution operation is realized with a precise adjustment of temperature of the iron core of magnets and has enabled to perform unique nuclear physics experiments. In order to extend the present activities, we have started studies for a future accelerator towards a new high-precision frontier of quark-lepton nuclear physics in the range of multi-GeV energies. Despite the fact that the final concept of the future accel-erator has not been decided yet, a “figure of 8 configura-tion ” synchrotron is being studied. Such a new multi-GeV high-performance accelerator is characterized as a pro-tons/electrons/light ions/polarized ions cooler-synchrotron-collider. R&D studies for several components of high-performance synchrotrons have been started already. 1
