Storage rings are usually associated with kilometer-long accelerators and particle colliders, but there is one miniature storage ring. The Nevatron, the first neutral-atom storage ring, is slightly larger than a quarter (25 mm or 1 in. in diameter) and weighs only 200 g (7 oz). While it cannot create antiprotons with teraelectronvolts (TeV) of energy, the Nevatron does bring together laser cooling and magnetic trapping to produce a storage ring for neutral rubidium-87 (⁸⁷Rb) atoms. This ring has allowed observation of multiple atomic orbits, dual cloud loading, and atomic cloud shaping. It also provides the basis for an atomic interferometer, a device that may one day provide the world's most sensitive gyroscope.
