The third phase of the Borexino experiment that's referred to as SOX is devoted to test the hypothesis of the existence of one (or more) sterile neutrinos at a short baseline (∼5-10m). The experimental measurement will be made with artificial sources namely with a 144 Ce- 144 Pr antineutrino source at the first stage (CeSOX) and possibly with a 51 Cr neutrino source at the second one. The fixed 144 Ce- 144 Pr sample will be placed beneath the detector in a special pit and the initial activity will be about 100 - 150 kCi. The start of data taking is scheduled for April 2018. The article gives a short description of the preparation for the first stage and shows the expected sensitivity.

Abstract

The third phase of the Borexino experiment that's referred to as SOX is devoted to test the hypothesis of the existence of one (or more) sterile neutrinos at a short baseline (∼5-10m). The experimental measurement will be made with artificial sources namely with a 144 Ce- 144 Pr antineutrino source at the first stage (CeSOX) and possibly with a 51 Cr neutrino source at the second one. The fixed 144 Ce- 144 Pr sample will be placed beneath the detector in a special pit and the initial activity will be about 100 - 150 kCi. The start of data taking is scheduled for April 2018. The article gives a short description of the preparation for the first stage and shows the expected sensitivity.
