    collider
    [ noun ]
    an accelerator in which two beams of particles are forced to collide head on
    <noun.artifact>


    collider \col*lid"er\ n. (Physics)
    a particle accelerator in which two separate beams of
    particles (usually of opposite charge) are circulated in
    opposite directions and directed so as to collide head on.
    This technique allows the production of collisions of higher
    energy than would be possible with a single beam produced by
    the same device.

    Syn: particle collider; colliding-beam accelerator;
    colliding-beam machine. [WordNet 1.5 +PJC]


    colliding-beam machine \colliding-beam machine\ n. (Physics)
    a particle accelerator in which two separate beams of
    particles (usually of opposite charge) are circulated in
    opposite directions and directed so as to collide head on; --
    called also {colliding-beam accelerator} and {collider}.

    Note: This technique allows the production of collisions of
    higher energy than would be possible with a single beam
    produced by the same device.

    Syn: particle collider; colliding-beam accelerator; collider.

    8. Texans in Congress will have a tough time persuading their colleagues to spend the billions of dollars needed to build the super collider, Sen. Lloyd Bentsen says.
    9. The House voted Wednesday to limit the federal government's spending on the super collider atom smasher to $5 billion.
    10. Officials will have to acquire more than 10,000 acres to build the super collider, a 54-mile oval in a tunnel in which protons and other particles will be accelerated to extreme speeds and smashed for scientific study.
    11. An aide to Sen. Lloyd Bentsen, D-Texas, said senators probably will act on the collider during appropriations.
    12. Supporters of the super collider say it is vital if this country is to be competitive with other nations in the area of basic science and technology.
    13. The House voted overwhelming approval Friday to a Department of Energy spending blueprint that includes $1.6 billion for the superconducting super collider, a massive high-energy physics project.
    14. The nation desperately needs highly trained scientists to tackle such challenges as the superconducting super collider, space stations, human genetic mapping and the AIDS epidemic, he says.
    15. The House Budget Committee has approved a plan that preserves spending on the super collider at more than $300 million next year _ a level that falls short of the president's request but exceeds Democratic leaders' initial recommendations.
    16. Because of budget contraints, Johnston said he was unable to support President Bush's rsuperconducting super collider receive $250 million in funds for the fiscal year that begins Oct. 1.
    17. After Texas bid for the super collider, state and federal officials notified the Wilburns their acreage would be needed if the state won.
    18. The Energy Department will decide within the next two weeks whether to build a smaller super collider atom-smasher or to spend more to keep the giant machine as originally envisioned, Sen. Phil Gramm, R-Texas, said Tuesday.
    19. Fire ants, infamous for chewing through underground cables and sparking shortages, have nibbled their way to the attention of federal scientists evaluating the Texas farmland designated as the site for the $4.4 billion super collider physics project.
    20. That's because the machine cost one-eighth as much as the $1 billion Large Electron-Positron collider, due to produce Z particles as soon as July at CERN.
    21. Mecham also was accused of pressuring a state panel to choose Craft as its lobbyist for Arizona's bid for the federal superconducting super collider.
    22. Rep. Silvio O. Conte, R-Mass., ranking Republican on the House Appropriations Committee, says the collider has no practical application.
    23. It is called a "super collider" because it would accelerate the protons until they packed some 20 times the punch _ or kinetic energy _ that existing machines can create.
    24. The House had cut the request to $200 million after critics called the science project an "expensive toy." The collider would be the most powerful and advanced facility in the world for examining subatomic particles.
