requires a near detector with high oxygen content, in order to measure
neutrino-oxygen cross sections relevant for predicting the anticipated signal
at the Super-Kamiokande water Cerenkov far detector. The best near detector would be a fine-grained scintillating
water detector. To this end, we have
developed scintillating liquids and gels with 70% water content. Solutions have been found for the problems
of chemical attack of the vessel and scintillating fibres by the liquid
scintillator, and for biological growth in the liquid. We are now at the stage of doing beam tests
on a large number of prototypes to establish the long-term viability of the
proposed detector design.
