Abstract: | There are plans to fill the Sudbury Neutrino Observatory with liquid scintillator after measurements with heavy water are
completed. The new experiment, known as SNO+, would make an excellent detector for geo-neutrinos. SNO+ would be located amidst
a thick and uniform region of continental crust, away from nuclear power reactors. As a result, the geo-neutrino signal to
reactor background ratio in SNO+ will exceed that from previous measurements. Geo-neutrino measurements by SNO+ will shed
light on the amount of uranium and thorium radioactivity in the crust, as well as deeper inside the Earth. Spectral information
from SNO+ geo-neutrino detection will provide the first direct measurement of the U/Th ratio. |
