Abstract: | For fifty years the isotope separation on-line (ISOL) technique has been used for the production of radioactive-ion beams
(RIBs). Thick-target ISOL facilities can provide very intense RIBs for a wide range of applications. The important design
parameters for an ISOL facility are efficiency, rapidity and selectivity of all steps of the separation process. To achieve
the anticipated beam intensities with the next-generation RIB facilities, the production rate in the ISOL target has to be
increased by orders of magnitude. This is only possible by adapting the projectile beam for optimum production cross-sections
and simultaneously minimizing the target heating due to the electronic stopping power of charged-particle projectiles. ISOL
beams of 75 different elements have been produced up to now and further beam development is under way to produce a still greater
variety of isotopes and to improve existing beams in intensity and purity.
