What is the highest beam energy Fermilab can achieve?
Fermilab’s four-mile Tevatron, the world’s second-highest-energy particle accelerator, can reach an energy level of 0.980 trillion electron volts (TeV) for each of its particle beams: clockwise-circulating protons and anticlockwise-circulating antiprotons. A proton-antiproton collision produces an energy of 1.96 TeV at the interaction points. In 1995, Tevatron Run I-b, the collisions ran at an energy level of 1.8 TeV, .9 TeV per beam, which was sufficient to discover the top quark. With the present energy level Fermilab hopes to continue discovering new particles in Run II of the Tevatron.
