Caption: The ion source in the Cockroft-Walton generator at the Fermi National Accelerator Laboratory (Fermilab) near Chicago. The Cockroft-Walton is at the beginning of the particle acceleration process. Electrons are added to hydrogen atoms in the ion source in the generator, & the resulting ions (a proton with 2 electrons attached) emerge from the high-voltage accelerator with an energy of 750 keV. They then travel through the Linear Accelerator or Linac, the Booster Accelerator, & finally the two giant magnet rings that form the Tevatron accelerator, which can whirl protons & antiprotons up to an energy of 1000 GeV (1 TeV). (May '84)
