Experiments based on horn produced (anti-)neutrino conventional beams are presently under development. The event rates are marginal for a definitive search, since they require very intense beams and extremely large detector masses. Zucchelli has proposed a method in which pure (anti-)nu_e beams are generated by the beta-decay of relativistic radio-nuclides stored in a high energy storage ring pointing towards a far away neutrino detector.
