Technical Challenges of the EURISOL Beta-beam

The so‐called beta‐beam concept [1] for accelerator‐driven neutrino experiments envisages the production of a pure beam of electron neutrinos (or their antiparticles) through the beta‐decay of radioactive ions circulating in a high‐energy storage ring. The conceptual design of a beta‐beam facility is ongoing within the framework of the EURISOL Design Study [2]. The required acceleration and accumulation of an unprecedented number of ions brings many challenges. Those most recently addressed are presented in this paper together with a brief overview of some of the salient features of the current design machine by machine.
