A Scandium Calibration Source for the SNO+ Experiment — •Axel Boeltzig, Nuno Barros, Felix Krüger, Belina von Krosigk, Valentina Lozza, Laura Neumann, Johannes Petzoldt, Arnd Sörensen, and Kai Zuber — TU Dresden, Germany

The SNO+ experiment is the successor of SNO (Sudbury Neutrino Observatory), for which the detector will be filled with liquid scintillator. Located 2 km underground (equivalent to a shielding of about 6 km of water) in a mine near Sudbury, Canada, SNO+ will be a low-background experiment studying different aspects of neutrinos.

The SNO+ detector calibration is scheduled to begin in mid-2013 with a water-filled detector and in 2014 filled with liquid scintillator. One of the sources designated for this calibration will use the γ rays following the beta decay of 48Sc. The sum of their energies is 3.333 MeV for the main decay branch, which is close to Q=3.371 MeV for the neutrino-less double beta decay of 150Nd that SNO+ plans to investigate.

Due to the 48Sc half-life of 43.67 h, the source has to be produced shortly before the calibration via (n,p) reactions on 48Ti. Safety, radiopurity and cleanliness are further important issues for its application. The current status of the source development will be presented. This work is supported by the German Research Foundation (DFG).
