Abstract
A radio-frequency type charged particle accelerator includes a RFQ accelerator and a rear stage RF accelerator both of which are contained in a single evacuated chamber. The RFQ accelerator has quadrupole electrodes positioned along a traveling path of the charged particle and bunches and accelerates a charged particle beam by receiving a radio-frequency power from a radio-frequency power source and resonating. The rear stage RF accelerator is disposed in a rear stage of the RFQ accelerator and accelerates or decelerates the energy of the charged particle beam accelerated by the RFQ accelerator by receiving the radio-frequency power from the radio-frequency power source and resonating. A separating plate is disposed in the single evacuated chamber to separate the RFQ accelerator from the rear stage RF accelerator so that the RFQ accelerator and the rear stage RF accelerator work independently of each other.
