要旨:
The Borexino experiment has begun data taking in
May 2007 after a long R&D work and preparation. The
liquid scintillator purity exceeds even optimistic
expectations, and the first detection of 7Be solar
neutrinos has been possible after less than two
months of data taking. This note shows briefly
which are the main issues that were addressed in order to obtain such an extreme radiopurity, the detector performance and a few details concerning
this first result.
