Together with other teams of Nishina Center accelerator division, maintaining and improving the RIBF cyclotron complex. The accelerator provides high intensity heavy ions. Our mission is to have stable operation of cyclotrons for high power beam operation. Recently stabilization of the rf system is a key issue to provide 10 kW heavy ion beam.
Major Research Subjects are:(1)RF technology for Cyclotrons
(2)Beam-RF correlation analysis
(3)Operation of RIBF cyclotron complex.
(4)Maintenance and improvement of RIBF cyclotrons.
(5)Design and construction of new injector linac.
(6)Single turn operation for polarized deuteron beams.
