Accelerators are ring-shaped or linear devices that accelerate charged particles. More powerful than any other microscope, high-energy accelerators allow physicists to study matter at the smallest scale human beings have ever seen, exposing the quarks inside a proton. At the same time, high-energy accelerators can produce collisions that recreate the conditions of the early universe – though in a much smaller volume. Creating tiny fireballs of high density and high temperature, physicists produce the particles that were abundant in the early universe, a trillionth of a second after the Big Bang.

A device found in some semiautomatic firearms that, through mechanical advantage or spring energy, transfers kinetic energy from one part of the mechanism to another with the resultant speeding up of the action.

a scientific instrument that increases the kinetic energy of charged particles

a laboratory machine that produces energetic beams of sub-atomic particles

A device for imparting energy of motion to charged particles.

Any device used to impart kinetic energy to electrically charged particles including, but not limited to, electrons, protons, deuterons and helium ions. This includes equipment designed for and used only for the production of X-rays of 0.9 MeV or greater and equipment capable of discharging nuclear particles into a medium external to the accelerating device.

A device attached to a dry-pipe sprinkler system for the rapid removal of the air in the system; a device to control the speed of a vehicle by regulating the fuel supply.

A machine used to accelerate particles to high speeds (and thus high energy compared to their rest mass-energy).

a machine which accelerates charged particles to high energies

A device that accelerates charged atomic particles to high energies. An x-ray machine or a betatron is an accelerator.

A device (i.e., machine) used to produce high-energy high-speed beams of charged particles, such as electrons, protons, or heavy ions, for research in high-energy and nuclear physics, synchrotron radiation research, medical therapies, and some industrial applications. The LEP collidor is an electron-positron accelerator.

Device used to increase the energy of particles, which then collide with other particles. Major types are linear accelerators and circular accelerators. The name refers to the path taken by the accelerated particle.

(also exhauster): portion of dry-pipe system that bleeds air or shunts air pressure below the clapper valve when sprinkler pipe pressure drop is sensed, thus speeding operation of the valve to fill the system with water.

A solvent, or other material, which is added to an ink in order to increase its drying rate, i.e.. to make it dry quicker.

A device used in an automatic or semiautomatic firearm to increase the speed of the bolt's rearward travel by the application of leverage at the critical point of travel.
