Radioactive Ion Accelerators
H. L. Ravn/CERN, EP
Abstract
Ion beams of the unstable isotopes of the elements with energies above the
coulomb barrier are more and more in demand for exploring the boundaries of the
chart of nuclides. After a short introduction to the physics case of
Radioactive Ion Beams (RIB) the following subjects are discussed in more detail
The facilities and projects in the world
The principles of the various radioactive ion-accelerators
The drivers accelerators and reactions for production of the rare nuclei
The nuclear targets for high intensity beams
Ion sources for efficient and selective ionization
The low energy injector, bunching and charge breeding
The post accelerator
Emphasis is put on the ISOL-post-accerlerator metod that presently give the
highest intensities. In here the nuclei of interest are produced and
thermalised in a thick target from which they subsequently are extracted,
conditioned and post accelerated.
