Quickening

accelˈerātor noun

Any person or thing that accelerates, esp a substance that accelerates chemical action, a nerve or muscle that increases rate of action, an apparatus or device for increasing the speed of a machine, computer, etc, or one for imparting high energies to atomic particles. Devices for accelerating charged particles include the cyclotron type (for accelerating the heavier particles, such as protons; used in the treatment of cancer), and modifications of this, such as the synchrocyclotron type and the synchrotron type (for accelerating electrons). Other types of accelerators are the proton synchrotron (of which examples are the cosmotron and the bevatron), the betatron (for accelerating electrons; used in medicine and industry), linear accelerators and electron ring accelerators
