Tevatron, Particle accelerator in Batavia, US
The Tevatron is a particle accelerator that sent protons and antiprotons racing through a circular tunnel four miles around, buried 25 feet below ground at Fermilab. The machine relied on more than 1,000 superconducting magnets to steer these particles and make them loop through the tunnel tens of thousands of times each second.
This accelerator began operating in 1983 and held the position of the world's second most powerful particle collider until 2011. The facility was shut down as the newer Large Hadron Collider in Europe demonstrated superior capabilities.
Scientists at the Tevatron made groundbreaking discoveries in 1995, including the confirmation of the top quark's existence through particle collision experiments.
The site sits within Fermilab's grounds and is no longer in active operation, though visitors can view the aboveground facilities. Plan your visit during the research center's regular operating hours to explore the campus properly.
Two massive detectors sat at opposite points along the ring, each weighing about 5,000 tons and rising three stories high above ground. These instruments recorded every collision event and helped physicists spot rare particles emerging from the smashed projectiles.
