linear accelerator

noun

, Physics.

1. an accelerator in which particles are propelled in straight paths by the use of alternating electric voltages that are timed in such a way that the particles receive increasing increments of energy.

linear accelerator

noun

1. an accelerator in which charged particles are accelerated along a linear path by potential differences applied to a number of electrodes along their path Sometimes shortened tolinac

linear accelerator

1. A type of particle accelerator that accelerates charged subatomic particles, such as protons and electrons, in a straight line by means of alternating negative and positive impulses from electric fields. Linear accelerators were largely supplanted by cyclotrons and other architectures that require less path length to achieve the same or higher particle velocities.
2. See Note at particle accelerator

Word History and Origins

Origin of linear accelerator¹

First recorded in 1930–35

Example Sentences

After some initial acceleration to get the ions moving, the beam enters the linear accelerator, which is what sets the particles really cruising.

From Science News

An early model of the linear accelerator also gave a beam of heavy positive ions at high energies.

From Project Gutenberg

It is called a linear accelerator because it accelerates particles in a straight line.

From Project Gutenberg

Another instrument, the heavy-ion linear accelerator (Hilac), accelerates ions as heavy as neon to about 15% the speed of light.
