Abstract

Borexino, a large volume liquid scintillator detector installed at Gran Sasso laboratory, demonstrated extraordinary sensitivity with respect to neutrino and antineutrino detection, reporting the best up to date results on low energy solar neutrino fluxes and performing geo-neutrino detection. Energy and position of 1 MeV events in Borexino are recon- structed with a precision of 5% and 14 cm respectively. These performances together with extremely low background provides an excellent opportunity for the study of short distance neutrino oscillations on the eV mass scale with artificial neutrino sources. The possible layouts for 51Cr (monoenergetic neutrino) and 144Ce-144Pr (antineutrino from β-decay) source experiments in Borexino and the expected sensitivity to sterile neutrinos for three possible designs of the experiment are presented.
