collidern.

Brit.

/kəˈlʌɪdə/, U.S.

/kəˈlaɪdər/

Etymology: < collide v. + -er suffix¹.

1. Physical Chemistry. A molecule or atom that collides with other molecules or atoms, esp. to an extent that needs to be allowed for in kinetics. Frequently with qualifying word, as strong collider, weak collider.

strong collider1968

1968 Jrnl. Chem. Physics 48 1285/2 In the second-order region the relative collisional activation efficiency depends simply on γ_γ, a relative measure of the transition probabilities of weak vs strong colliders.

1972 Robinson & Holbrook Unimolecular Reactions x. 324 It seems very reasonable to assume..that these sufficiently large molecules behave effectively as strong colliders.

1977 Chem. Physics Lett. 48 207 The magnetic field effect is only observed in the presence of colliders.

1979 Jrnl. Physical Chem. 83 93/2 Deviations from the behavior predicted..are termed weak collider (WC) effects.

2. Particle Physics. An accelerator in which two beams of particles are accelerated independently and made to collide, so as to increase the effective energy of the collision.

1979 Nature 29 Mar. 408/1 Another contender will be the p̄p collider planned at Fermilab using the superconducting magnet ring being installed to double the present accelerator's energy to 1,000 GeV; this may eventually allow 2,000 GeV to be reached in the collision.

1981 A. Salam in J. H. Mulvey Nature of Matter v. 116 It is proposed to build the world's biggest electron-positron collider, called LEP.

1985 National Geographic May 638/1 That relativity is..the basis for Fermilab's collider.
