Detector lens as a new tool for solar neutrino spectroscopy

The LENS detector is a ν _e-flavor real-time detector for measurement of low-energy solar neutrino flux and spectral shape, specifying the pp and ⁷Be neutrinos individually. It will complement future low-energy neutrino experiments (BOREXINO, HELLAZ, GENIUS), all of which are scattering experiments. The main goal of the LENS collaboration is to develop final formulation of Yb-and In-loaded liquid scintillators and to build a prototype of suitable volume to study the backgrounds and detector performance.
