Exotic ion-beams targets and sources

Exotic beams of short-lived radioisotopes are produced in nuclear reactions such as thermal neutron induced fission, target or projectile fragmentation and fusion reactions. For a given radioactive ion beams (RIB), different production mode are in competition. For each of them the cross section, the...

description Exotic beams of short-lived radioisotopes are produced in nuclear reactions such as thermal neutron induced fission, target or projectile fragmentation and fusion reactions. For a given radioactive ion beams (RIB), different production mode are in competition. For each of them the cross section, the intensity of the projectile beam and the target thickness define an upper production rate. The final yield relies on the optimisation of the ion-source, which shall be fast and highly efficient in view of the limited production cross section and on minimum diffusion time out of the target matrix or fragment catcher to reduce decay losses. Eventually, either chemical or isobaric selectivity is needed to confine unwanted elements near to the production site. These constraints are discussed for pulsed or dc driven RIB facilities and the solutions to some of the technical challenges will be illustrated by examples of actually scarcely produced near drip line elements.
