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

In the future, the investigation of superheavy elements could be even more efficient thanks to the new linear accelerator HELIAC, for which the first module was recently assembled at HIM and then successfully tested in Darmstadt, so that further, even more exotic and therefore presumably longer-lived nuclei will also be experimentally achievable.

From Science Daily

It’s not your local vet that has a $2 million linear accelerator that aims radiation at cancer tumors with pinpoint accuracy.

From Seattle Times

The new therapy, delivered by a high-energy linear accelerator Kaplan developed in the 1950s for medical use, was the first step in a Stanford-driven effort to turn the once fatal cancer of the lymph nodes into one that is now highly curable.

From Science Daily

In an XFEL, a linear accelerator, or linac, shoots electrons through magnets that shake the particles sideways and make them emit x-rays.

From Science Magazine

In a free electron laser, a linear accelerator, or linac, shoots a beam of high-energy electrons into a string of complex magnets called undulators.
