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.

A charged particle acceleration device, which eliminates the need for repeating alignment adjustment even in the case of repeating installation of the controllers, is provided, and a method for adjusting the same is provided. A charged particle acceleration deviceA includes: controllersconfigured to control a beam trajectoryof charged particles that pass through a ductto be inserted through the controllers; and a stagethat is supported by a framefixed to a base and reversibly moves the controllersin a direction of intersecting the beam trajectory
