Abstract
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 device 10A includes: controllers 15,15a,15b,15c configured to control a beam trajectory 12 of charged particles that pass through a duct 11 to be inserted through the controllers 15; and a stage 20 that is supported by a frame 16 fixed to a base and reversibly moves the controllers 15 in a direction of intersecting the beam trajectory 12.
Claims5
A charged particle acceleration device comprising:
- a controller configured to control a beam trajectory of charged particles that pass through a duct, the duct being inserted through the controller;
- and
- a stage that is supported by a frame fixed to a base and reversibly moves the controller in a direction of intersecting the beam trajectory, wherein
- the stage includes:
- a fixing plate to be fixed to the frame,
- a moving plate to which the controller is fixed, the moving plate being configured to move relative to the fixing plate, and
- a regulator configured to regulate movement of the moving plate with respect to the fixing plate.
A method for adjusting a charged particle acceleration device that includes:
- a controller configured to control a beam trajectory of charged particles that pass through a duct, the duct being inserted through the controller, and
- a stage that is supported by a frame fixed to a base and reversibly moves the controller in a direction of intersecting the beam trajectory, the method comprising:
- attaching an integrated structure including the duct, the controller, and the stage to the frame and then performing alignment adjustment with respect to the beam trajectory;
- moving the stage in such a manner that the controller is evacuated from the beam trajectory;
- disposing an adjuster on the beam trajectory and then adjusting incident conditions of the charged particles;
- evacuating the adjuster from the beam trajectory;
- and
- moving the stage in such a manner that the controller is returned to the beam trajectory.
