...expanded and cooled, they all but disappeared. Now they occur naturally only under certain conditions. To conjure them up, scientists have to re-create the fiery conditions that followed the Big Bang, not an easy task. Because the top is so heavy, only the most energetic collisions in the Tevatron are capable of producing the particle at all. In addition, this king of quarks has such an infinitesimal lifetime that its presence can be inferred only from the whispery contrails of other particles into which it promptly decays. Thus the detector designed by Fermilab's scientists consists of more than...
...quarks were culled from highspeed collisions between protons and antiprotons in the Tevatron particle accelerator at Fermilab--a circular underground track four miles long which rams particles together at speeds approaching that of light...
...dismay of scientists, no laboratory is even close to achieving such high energies. The recently-built Tevatron particle accelerator in Chicago falls short by a factor of about 10,000 trillion, or 10 with 16 zeroes following...
Fermilab. The machine most likely to find the top quark first is Fermilab's mighty Tevatron, which has been operating for 6 1/2 years beneath the waving grasses of the Illinois prairie. In the Tevatron, strong magnets guide subatomic particles through a circular tunnel that is 6.4 km (4 miles) in circumference. The accelerator is built as a ring so that particles can go around the track again and again, picking up speed with each lap. The ring was built large so that the particles would not have to make sharp turns...
...power 50% in the next year or two. CERN is also trying to persuade its member nations to put up the money to build a proton-proton collider in the same tunnel with LEP. Called the large had ron collider, it would be four times as powerful as the Tevatron and almost half as forceful as the proposed superconducting supercollider in Texas. Rubbia thinks he can finish the LHC several years ahead of the SSC and thus beat the Americans to many important discoveries. If the LHC measures up to Rubbia's expectations, SSC could end up standing for superfluous...
