The cascaded cyclotron system adopted in RIKEN RI Beam Factory (RIBF) has established stable deliveries of the world’s most intense heavy-ion beams. Beam Dynamics and Diagnostics Team is responsible for magnets, power supplies, beam instrumentation, computer control system and beam dynamic of the RIBF accelerator complex. We pursue further performance upgrades of the RIBF accelerator complex.
