The tandem accelerator is kept at high voltage and many ions are accelerated by use of the high voltage.
The ion sources on the deck, which are used for generation of negative ions, are installed outside of the accelerator, and several ion sources are always ready in operation.
Therefore, beam switching from one ion specie to another finishes in a short time, and experiments using desired ion beams can start readily after some handling of beam alignment. Ion species available for acceleration are listed in green in the table below.
Inert gases are accelerated from positive charge states because negative charge states are not available for inert gases. The positive ion source is installed at the high voltage terminal of the accelerator. Electron cyclotron resonance is applied to the positive ion source, and hydrogen, nitrogen and oxygen ions can be accelerated by the ion source. The development for the acceleration of metal ions is now in progress.
