The Tool: The Tevatron

To explore the smallest of the small, the particles inside the atom, scientists use the largest of scientific instruments, particle accelerators with outer dimensions measured in miles. These giant tools of particle physics can accelerate subatomic particles to very close to the speed of light (3.0 X 108 meters/sec). In experiments to find and measure the top quark, Fermilab physicists use the world's most powerful accelerator, the Tevatron.

The Tevatron will accelerate beams of protons and antiprotons. The protons and antiprotons travel in opposite directions around the Tevatron's four mile circumference. When the proton and antiproton meet, they collide with enough energy to allow the physicists to explore the decay of the kaon particle.
