n. Any of several forms of particle accelerator in which two opposing beams of particles collide
the GNU version of the Collaborative International Dictionary of English
n. 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.

Word Usage
"Particle physics might make it “easy” to do these tests, if you think waiting three decades to build a suitable collider is easy, but the principle holds for AGW theory as well."
