Abstract
An objective of the invention is to provide an acceleration cavity, an accelerator, and a resonance frequency adjustment method of an acceleration cavity that can change the natural resonance frequency of the acceleration cavity without occupying space between adjacent accelerator cavities. A QWR includes: a body portion whose axial direction is parallel to the vertical direction, and having a cylindrical side face portion; an upper face portion provided in an upper part of the body portion and is a plate-shaped member; and a deformation adjustment portion applying a pressing force on the upper face portion to deform the upper face portion.
