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.
