In the exciting arena of the solar neutrino research a new actor is expected to come soon in the game: Borexino. This massive, calorimetric, liquid scintillation detector, in advanced phase of installation in the underground Gran Sasso Laboratory, will be focused towards one of the fundamental issues of this field, i.e. the direct determination of the flux of the neutrinos produced in the 7Be electron capture reaction in the Sun. As a pilot program for the full detector, the Counting Test Facility operated for two years at Gran Sasso, provided the convicing evidence that the fundamental technological challenge of the experiment, the achievement in the scintillator of unprecedented radiopurity levels, can be accomplished successfully, thus opening the way to the realization of the experiment.
