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 (â¼5-10m). The experimental measurement will be made with artificial sources namely with a144Ce-144Pr antineutrino source at the first stage (CeSOX) and possibly with a51Cr neutrino source at the second one. The fixed144Ce-144Pr 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.
