 D0 under construction, the installation of the central tracking system The D0 experiment consists of a worldwide collaboration of scientists conducting research on the fundamental nature of matter. The experiment is located at the world's premier high-energy accelerator, the Tevatron Collider, at the Fermi National Accelerator Laboratory (Fermilab) in Batavia, Illinois, USA. The research is focused on precise studies of interactions of protons and antiprotons at the highest available energies. It involves an intense search for subatomic clues that reveal the character of the building blocks of the universe. Image File history File links Public. ...

Overview
 D0 Detector with large liquid argon calorimeter The D0 experiment is located at one of the interaction regions, where proton and antiproton beams intersect, on the Tevatron synchrotron ring, labelled 'D0'. A fundamental interaction is a mechanism by which particles interact with each other, and which cannot be explained by another more fundamental interaction. ...

Tevatron is a circular particle accelerator (or synchrotron) at the Fermi National Accelerator Laboratory in Batavia, Illinois. ...
A synchrotron is a particular type of cyclic particle accelerator in which the magnetic field (to turn the particles so they circulate) and the electric field (to accelerate the particles) are carefully synchronized with the travelling particle beam. ...
The experiment is a test of the Standard Model of particle physics. It is sensitive in a general way to the effects of high energy collisions and so is meant to be a highly model independent probe of the theory. This is accomplished by constructing and upgrading a large volume elementary particle detector. The Standard Model of Fundamental Particles and Interactions The Standard Model of particle physics is a theory which describes the strong, weak, and electromagnetic fundamental forces, as well as the fundamental particles that make up all matter. ...

The Compact Muon Solenoid (CMS) is an exampel of a large particle detector. ...
The detector is designed to stop as many as possible of the subatomic particles created from energy released by colliding proton/antiproton beams. The intersection region where the matter-antimatter annihilation takes place is close to the geometric center of the detector. The beam collision area is surrounded by tracking chambers in a strong magnetic field parallel to the direction of the beam(s). Outside the tracking chamber are the pre-shower detectors and the calorimeter. The Muon Chambers form the last layer in the detector. The whole detector is encased in concrete blocks which act as radiation shields. A subatomic particle is a particle smaller than an atom: it may be elementary or composite. ...
