LINAC 1

LINAC 1 was the first particle injection system used within a proton particle beam-accelerator within CERN. Designed during the 1950s the LINAC was first active in 1958-59. Starting in 1964 the LINAC was used to accelerate deuterons continuing to be used for this during the 1970s. LINAC1 ceased to be used in experiments in 1992.

The LINAC is an additional accelerator utilized in order to provide energy that particles absorb resulting in these having a motion closer to c.

Linear particle accelerator

A linear particle accelerator (often shortened to linac) is a type of particle accelerator that greatly increases the kinetic energy of charged subatomic particles or ions by subjecting the charged particles to a series of oscillating electric potentials along a linear beamline; this method of particle acceleration was invented by Leó Szilárd. It was patented in 1928 by Rolf Widerøe, who also built the first operational device at the RWTH Aachen University in 1928, influenced by a publication of Gustav Ising.

Linacs have many applications: they generate X-rays and high energy electrons for medicinal purposes in radiation therapy, serve as particle injectors for higher-energy accelerators, and are used directly to achieve the highest kinetic energy for light particles (electrons and positrons) for particle physics.

The design of a linac depends on the type of particle that is being accelerated: electrons, protons or ions. Linacs range in size from a cathode ray tube (which is a type of linac) to the 3.2-kilometre-long (2.0 mi) linac at the SLAC National Accelerator Laboratory in Menlo Park, California.
