The Bevatron is a particle accelerator operated at the Lawrence Berkeley National Laboratory from 1954 to 1993. It was designed to test the hypothesis that every particle has a corresponding antiparticle, and accelerated protons to high enough energies (6.2 GeV) that antiprotons might be produced in a collision with a fixed target. The Bevatron successfully produced antiprotons, and remained a productive research facility through several upgrades until its decommissioning in 1993.
