Abstract
We discuss a design study devoted to a construction of the Beta beams facility at CERN, a next generation European facility aiming for a production of pure and collimated ultra-relativistic beam of electron (anti)neutrinos with help of accelerated beta-decaying radioactive ions circulating in a storage decay ring. This high intense source of (anti) neutrinos directed towards a remote underground neutrino detector will allow to measure neutrino oscillations with high accuracy offering a unique chance for establishing a value of the theta(13) mixing angle and CP violating phase. Recently, a significant progress have been achieved on the conceptual design of high power targets required for a production and an extraction of two baseline isotopes, He-6 and Ne-18, at the unexampled rate of several 10(13) ions/s. There is a possibility to produce these isotopes using the so-called Isotope Separation On Line (ISOL) method at the ISOLDE facility (CERN). The He-6 production is realized by taking advantage of the Be-9(n, alpha)He-6 reaction and with help of spallation neutrons and porous BeO target material. The production of Ne-18 through the F-19(p, 2n)Ne-18 reaction at required intensities is even more challenging. Currently, a molten salt (NaF) loop target is proposed for a production of high rate of Ne-18 required for the Beta beams project. The progress on the design study associated with new data and plans for future is briefly presented.
