Ion beams of unstable (radioactive) nuclei, most of which are so short-lived that they do not occur naturally on Earth—hence the term rare isotopes. Rare isotopes are typically produced and isolated in the laboratory by suitable nuclear reactions or decays such as fission. Rare-isotope beams are either produced in-flight from fragmentation or fission of stable beams or they are produced in specialized ion sources from where they are extracted as particle beams that can be manipulated by specialized electromagnetic devices to produce beams of the desired characteristics such as purity, particle velocity, direction, and time structure. Several facilities worldwide are operational, and more powerful ones are under construction to explore the vast scientific discovery potential offered by rare-isotope beams. We will use the term rare-isotope beams, noting that such beams are also often referred to as radioactive beams or exotic beams. See also: Ion sources; Isotope; Nuclear fission; Nuclear reaction
