The Cosmotron was a particle accelerator, specifically a protonsynchrotron, at Brookhaven National Laboratory. Its construction was approved by the Atomic Energy Commission in 1948, it reached its full energy in 1953, and it continued running until 1968. It was the first particle accelerator to impart kinetic energy of in the range of GeV to a single particle, accelerating protons to 3.3 GeV. It was also the first accelerator to allow the extraction of the particle beam for experiments located physically outside the detector. It was used to observe a number of mesons previously seen only in cosmic rays, and to make the first discoveries of heavy, unstable particles (called V particles at the time). A 1960s single stage 2MeV linear Van de Graaff accelerator, here opened for maintenance A particle accelerator is a device which uses electric and/or magnetic fields to propel electrically charged particles to high speeds. ... Properties In physics, the proton (Greek proton = first) is a subatomic particle with an electric charge of one positive fundamental unit (1. ... A synchrotron is a particular type of cyclic particle accelerator in which the magnetic field (to turn the particles so they circulate) and the electric field (to accelerate the particles) are carefully synchronized with the travelling particle beam. ... Aerial view of Brookhaven National Laboratory. ... Almost a year after World War II ended, Congress established the United States Atomic Energy Commission to foster and control the peace time development of atomic science and technology. ... Kinetic energy is energy that a body has as a result of its speed. ... A GEV (or Ground Effect Vehicle) is vehicle that takes advantage of the aerodynamic principle of ground effect (or Wing-in-ground). ... In order to create a particle beam one must have a section called an ion source in which the beam is created by exciting electrons. ... This article needs to be cleaned up to conform to a higher standard of quality. ... Cosmic rays can loosely be defined as energetic particles originating outside of the Earth. ...
