DZero detector shortly after Run I. The DZero 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. Beams of protons and antiprotons collide at nearly the speed of light in Fermilab's Tevatron accelerator. Millions of times a second,protons and antiprotons burst into showers of secondary particles: quarks,electrons,muons,neutrinos,... there are more than a hundred possibilities. By studying the particles,physicists learn about the elementary building blocks and fundamental forces that determine the nature of matter%u2014and the ultimate structure and evolution of the universe. Physicists need more than accelerators in order to ''see'' high energy collisions. That's why scientists have designed and built particle detectors like DZero. They are essentially huge ''cameras'' that can take more than a million ''snapshots'' of particle collisions every second. They can count particles,identify their tracks,measure their energy,record their time of flight and distinguish one particle from another. Detectors can be as tiny as a computer chip or as huge as a house,containing many thousands of tons of material | |
