The Fermilab Tevatron collides protons with antiprotons to create luminosity at a center of mass energy of 1.96 Tev. This talk will start with a description of the steps performed as protons and antiprotons make their way through the chain of Fermilab accelerators before reaching the Tevatron. The rest of the talk will focus on the Tevatron, the factors that determine the luminosity, and some of the fundamental limitations of creating luminosity.
