The ATLAS Project
Information courtesy of the ATLAS public page.
ATLAS is a particle physics experiment at the Large Hadron Collider (LHC) at CERN. The detector will search for new discoveries in the head-on collisions of protons at energies up to 14TeV. ATLAS will learn about the basic forces that have shaped our Universe since the beginning of time and that will determine its fate. Among the possible unknowns are the origin of mass, extra dimensions of space, unification of fundamental forces, and evidence for dark matter candidates in the Universe. Scientists from 37 countries wok on the ATLAS project, coming from over 172 universities. For the next 15-20 years, these scientists will study the information produced by the LHC. The ATLAS detector is about 45 meters long, more than 25 meters high, and weighs about 7,000 tons. It is about half as big as the Notre Dame Cathedral in Paris and weighs the same as the Eiffel Tower or a hundred empty 747 jets.
