Ring cyclotron is a kind of AVF cyclotron. The magenets are radially separated several sectors to focus strongly beam.
Huge electro-magnet for four-sector cyclotron was installed at the Institute of Physical and Chemical Research (RIKEN) of Japan.
Combined with a heavy-ion linear accelerator and AVF Cyclotron, this separated sector cyclotrons accelerates variety of particles from proton to uranium.
