The radio frequency is coasely changed over the range of 18-45 MHz with movable-boxed accommodated inside the resonators. An acceleration voltage of as much as 275 kV is generated at a frequency of 32.6 MHz, which corresponds to the top enegy of 135 MeV/nucleon for light ions. The acceleration harmonics of 5 is used for the AVF injection, while 9,10, and 11 for the RILAC injection. The RILAC works at the same frequency as the RRC, while AVF at half ot the RRC frequency. The extraction radius is desinged to be four times the injection radius, so that the final velocity increased by four times an incident velocity.
