Design Study of the Intermediate Energy Particle Accelerator Complex

An intermediate energy particle accelerator complex has been proposed as a new accelerator facility of RCNP. This variable energy accelerator complex covers a wide energy range above the present RCNP cyclotron and accelerates ions from proton through uranium with high intensity and good beam quality. Protons of 550 MeV are available for a meson factory. The main accelerator is divided into two cascade ring cyclotrons. An ordinary AVF cyclotron and a Wideröe type variable frequency linac will be used as light ion and heavy ion injector, respectively. A 1/3.5 scale model of the 1st ring magnet and a 1/10 scale model of variable frequency single gap acceleration cavities are being studied.
