Summary
The Borexino experiment for the measurement of low-energy neutrinos started data taking on May 15, 2007. After only two months of measuring time, the Borexino collaboration for the first time succeeded to unambiguously identify in real time neutrinos which are released in the electron capture of 7Be in the core of the Sun and thereby to verify independently neutrino oscillations. Besides this, also neutrinos from the Earth’s interior and from far distant nuclear reactors generate signals in Borexino.
