Main Injector Tunnel
Visible in this image are two accelerators. One at the floor, and another at the ceiling. The lower accelerator is the Main Injector, which accelerates protons and antiprotons to about 70% the speed of light before directing them around Fermilab to whichever experiment needs them. Above, is the Recycler. The Recycler, as the name implies, collects leftover antiprotons and stores them.
