Bevatron

The Bevatron was a particle accelerator — specifically, a weak-focusing proton synchrotron — at Lawrence Berkeley National Laboratory, U.S., which began operating in 1954.^[1] The antiproton was discovered there in 1955, resulting in the 1959 Nobel Prize in physics for Emilio Segrè and Owen Chamberlain.^[2] It accelerated protons into a fixed target, and was named for its ability to impart energies of billions of eV ("billions of eV synchrotron").
