Charged particle accelerator and method for building charged particle accelerator

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
