A radioactive ion beam facility—in short a RIB facility—produces ions of short-lived nuclei and accelerates them to energies of 0.1&ellip;10 MeV per nucleon or even higher. In this process it is important that the resulting RIB beams are free from nuclei of neighboring isobars or of neighboring elements. This task requires the production and ionization of the nuclei of interest as well as separating them from all others with a high-mass resolving power and small-mass cross contaminations. When constructing such a facility it also is very important to find ways that allow the accelerated ions to be provided to different experiments at least quasi simultaneously. ©1999 American Institute of Physics.
