SPIRAL II : Preliminary design study

LPSC-si ;There is currently in the nuclear physics community a strong interest in the use of beams of accelerated radioactive ions. Although a fast glance at the nuclide chart immediately shows the vast unknown territories on the neutron-rich side of the valley of beta stability, only few projects are concerned with the neutron-rich nuclides.The SPIRAL-II program aims at studying the techniques for delivering beams of neutron-rich radioactive nuclidesat energies of a few MeV per nucleon. For that purpose, some study groups have been formed to evaluate the possibility ofsuch a project inthe different components: physics case, target-ion sources, drivers, postacceleration and general infrastructure. The organization of the project study is given at the end of this report. You will find also the name of all the people involved in the study. The following report presents an overview of the study
