加速器(かそくき) is a technical term for a machine that accelerates charged particles to high speeds. It is most commonly encountered in physics and medical contexts.

Full form

The full term is 粒子(りゅうし)加速器(かそくき) (particle accelerator), but 加速器(かそくき) alone is commonly used.

Types

  • 線形(せんけい)加速器(かそくき): linear accelerator (linac)
  • 円形(えんけい)加速器(かそくき): circular accelerator
  • 医療用(いりょうよう)加速器(かそくき): medical accelerator (used in radiation therapy)

Forms

加速(かそく) (acceleration) + 器(き) (device/instrument). The suffix 器(き) is productive for naming instruments and devices.

Japan context

Japan has major accelerator facilities, including KEK (高(こう)エネルギー加速器(かそくき)研究(けんきゅう)機構(きこう)) in Tsukuba.
