Intense relativistic (anti)neutrino beams are an unique tool required to study fundamental properties of neutrinos such as neutrino oscillation parameters, as well as their Majorana or Dirac nature, the lepton number conservation hypothesis and the absolute neutrino mass scale. Such beams originate from acceleration of β-decaying radioactive ions (”Beta beams”). The conceptual design study of high power targets required for the production and extraction of two low-Q baseline radioactive isotopes, 6He and 18Ne, to be accelerated and stored at decay ring will be presented.
