What about a beta-beam facility for low-energy neutrinos?

A novel method to produce neutrino beams has recently been proposed: the beta beams. This method consists in using the β decay of boosted radioactive nuclei to obtain an intense, collimated and pure neutrino beam. Here we propose to exploit the beta-beam concept to produce neutrino beams of low energy. We discuss the applications of such a facility as well as its importance for different domains of physics. We focus, in particular, on neutrino–nucleus interaction studies of interest for various open issues in astrophysics, nuclear and particle physics. We suggest possible sites for a low-energy beta-beam facility.
