storage rings[′stȯr·ij ‚riŋz]
elements of crossed-beam charged-particle accelerators. The intensity of accelerated particles in a single pulse of modern accelerators is usually in the range of 1012-1013 particles, which does not provide the required effectiveness for physical experiments with crossed beams. For this reason, the particles from tens or hundreds of pulses are collected in special storage rings. A storage ring consists of a permanent or quasipermanent magnet, a ring-shaped vacuum chamber, a device for injection and displacement of a particle beam along the chamber, and an acceleration gap. In some versions, storage rings are incorporated into the main accelerator.
