Tevatron Smashes no More: Higgs Boson May Have to Wait



""The Tevatron, the most successful atom smasher in the world, shut down for the last time 3:40 p.m. on Friday. It played a big role in the quest to find the elusive Higgs Boson or "God particle" and is run by the Fermi National Accelerator Laboratory.

"We're thinking of it as if we're pulling the plug on our favorite uncle," Roger Dixon, head of the accelerator division at Fermilab, told Fox News on Thursday.

 Operators shut down Tevatron by switching off dual beams of particles that have been colliding since 1985.

 "That will be it," Gregorio Bernardi, a physicist at Fermilab, told the media. "Then we'll have a big party."

 The decision to terminate Tevatron put an end to a fruitful era in research during which time scientists used Tevatron to search for the origin of mass. They were also able to look for new particles that could explain the nature of the universe itself.

 Tevatron sent protons and anti-protons around a four-mile track nearly at the speed of light before smashing them together in order to free hidden particles that make up matter.  Tevatron discovered three of the 17 particles that scientists think are fundamental to the universe.  Its biggest success came in in 1995 when it found a subatomic particle called the top quark, the last of six fundamental building blocks of matter to be discovered.""
