Abstract
A technique for outputting heterologous ions having the same per-nucleon energy at different timings by using one ion source is provided. An ion generation device includes: an ion generation energy setter that causes first ions and second ions generated by ionization in a vacuum chamber to be emitted in a mixed state from an opening; an electric-field voltage adjuster that imparts a same predetermined per-nucleon energy to each of the first and second ions by applying electric potential formed between the opening and extraction electrodes while switching the electric potential between first and second electric-field voltages; and an excitation current adjuster that causes the first and second ions to be outputted at different timings by supplying a coil of a separation electromagnet with an excitation current while switching the excitation current between first and second excitation currents.
