A particle accelerator in which a beam gains kinetic energy along a substantially straight sequence of accelerating structures.
A collider whose main beams are accelerated along opposing linear beamlines and brought into collision without returning repeatedly around a storage ring. Sources, beam conditioning, final focus, extraction, and dumps are essential parts of the layout, as well as the main accelerating structures.
A proposed electron–positron linear collider using normal-conducting RF structures powered through a separate drive-beam deceleration system. The 2012 conceptual design studied multi-TeV operation and lower-energy stages; its TeV design used approximately MV/m main-linac gradients. Historical design targets should be distinguished from later staging revisions and from operating measurements. [ref]

A proposed electron–positron linear collider based on superconducting RF acceleration. The 2007 reference design relevant to an exam-era comparison targeted GeV centre-of-mass energy and peak collider luminosity , with approximately km total footprint. These are historical design parameters, not achieved machine performance. [ref]

A linear particle accelerator, or linac, is a type of particle accelerator that accelerates charged particles, such as electrons, protons, or other ions, in a straight line. Unlike circular accelerators, which use magnetic fields to bend the path of the particles into a circular trajectory, linacs utilize a series of accelerating structures to impart energy to the particles as they travel through them.
