The DØ Experiment consists of a worldwide collaboration of scientists conducting research on the fundamental nature of matter. The DØ experiment (the CDF experiment as well) is located at the world's premier high-energy accelerator, the Tevatron Collider, at the Fermi National Accelerator Laboratory (Fermilab) (Department of Energy [DOE] national laboratory) in Batavia, Illinois, USA.

By the way: 

The name of our detector is based on the naming scheme of the Tevatron Collider (schematic view of the Tevatron), which is divided into 6 sections. The DØ - Detector is  located in section D, precisely at the point called 'D0', whereas the CDF - Detector for example can be found in section B (at the point 'B0'). The main injector is connected to the Tevatron in section F (at the point 'F0').
