Betaspectroscopy of a Ce/Pr-144 sample for the SOX experiment — •Simon Appel for the BOREXINO collaboration — TU München

The very low radioactive background of the Borexino detector, its large size, and the well proved capability to detect both low energy electron neutrinos and anti-neutrinos make an ideal case for the study of short distance neutrino oscillations in the ev scale, which is the goal of the SOX experiment.

As neutrino generator SOX will use a Ce/Pr-144 source with expected activity aorund 100 kCi. The experiment will look for distortions in the anti-neutrino spectrum. Therefore it is crucial to have a good understanding of the original spectrum. This is done via betaspectroscopy of a Ce/Pr-144 sample, based on a plastic scintillator setup. To distinguish electron and gamma particles the setup is equipped with an multi-wire-chamber.

This talk will present the latest results of the setup.
