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 10 A includes: controllers 15,15 a, 15 b, 15 c 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.

First claim

The invention claimed is:

1. 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.

2. The charged particle acceleration device according to claim 1 , wherein the stage further includes a linear-motion driver that axially rotates to move the moving plate with respect to the fixing plate.

3. The charged particle acceleration device according to claim 1 , further comprising another stage aside from the stage on which the controller is installed,
wherein the another stage is configured to reversibly move an adjuster to be operated during an adjustment stage in a direction of intersecting the beam trajectory.

4. The charged particle acceleration device according to claim 1 , wherein at least one of the fixing plate and the moving plate are partially dividable except for an area to be occupied by the controller during normal operation.

5. 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.
