Arial photo of the Fermilab site.  What excactly does the Fermilab do you ask? Well in the simplest terms possible the lab studies the tiniest building blocks of matter to learn and understand more about the forces involved in holding them together and the forces that separate them, otherwise known as particle physics. To study these subatomic particles the scientist must smash them together in order to see what comes flying out. One of the most interesting parts about the Fermilab is the immense size of the equipment used to carry out the experiments. The Tevatron is the highest energy particle accelerator in the world. It is located 30 feet below the surface and has a circumference of approximately four miles. The Tevatron uses accelerators that help add energy to the subatomic particles so that they can travel around the four-mile loop 50,000 times a second at a speed of 99.9999 % of light. To help study the collisions there are two collider detectors ( CDF and DZero), each about the size of a four story building. To help compute all of the information the lab uses a supercomputer. This supercomputer can handle over 80,000 gigabytes or 80 terabytes a year. Inside the Tevatron you will find two kinds of particles, protons and antiprotons. The scientists send the two different particles in opposite directions and then steer them into a head on collision with each other. These collisions occur in the center of the CDF detector and the DZero detector. These detectors house tons of sensors and equipment that relay the necessary information to the scientists.
