1. A charged particle beam injector comprising:
a first ion source that generates first nuclide ions;
a first linear accelerator that linearly accelerates the first nuclide ions to form a first charged particle beam;
a second ion source that generates second nuclide ions;
a second linear accelerator that linearly accelerates the second nuclide ions to form a second charged particle beam;
a switching electromagnet that injects one of the first charged particle beam and the second charged particle beam into an inflector of a main accelerator;
a first extraction electromagnet that bends the first nuclide ions by electromagnetic force and injects the first nuclide ions into the first linear accelerator;
a second extraction electromagnet that bends the second nuclide ions by electromagnetic force and injects the second nuclide ions into the second linear accelerator;
a third ion source that generates third nuclide ions; and
a third extraction electromagnet that bends the third nuclide ions by electromagnetic force, then causes the third nuclide ions to pass straight through the first extraction electromagnet or the second extraction electromagnet, and then injects the third nuclide ions into the first linear accelerator or the second linear accelerator.
