Ion generation device, ion generation method, and ion generation program

An ion generation method comprising:

• emitting first ions and second ions in a mixed state from an opening, the first ions and second ions being generated by ionization in a vacuum chamber while switching output intensity of an ion generation energy supplier;
• imparting a same predetermined per-nucleon energy to each of the first ions and the second ions by applying an electric potential to be formed between the opening and an extraction electrode in such a manner that the electric potential is switched between a first electric-field voltage and a second electric-field voltage depending on switching of the output intensity;
• and
• outputting the first ions and the second ions at different timings by supplying a coil of a separation electromagnet with an excitation current in such a manner that the excitation current is switched between a first excitation current and a second excitation current depending on switching of the output intensity.

A non-transitory computer-readable medium storing executable instructions that allow a computer to perform:

• an emitting process of causing first ions and second ions to be emitted in a mixed state from an opening, the first ions and second ion being generated by ionization in a vacuum chamber while switching output intensity of an ion generation energy supplier;
• an imparting process of imparting a same predetermined per-nucleon energy to each of the first ions and the second ions by applying an electric potential to be formed between the opening and an extraction electrode in such a manner that the electric potential is switched between a first electric-field voltage and a second electric-field voltage depending on switching of the output intensity;
• and
• an outputting process of causing the first ions and the second ions to be outputted at different timings by supplying a coil of a separation electromagnet with an excitation current in such a manner that the excitation current is switched between a first excitation current and a second excitation current depending on switching of the output intensity.
