ABSTRACT
The Sudbury Neutrino Observatory (SNO) detector is a 1000 tonne heavy water Čerenkov detector designed to study the intensity, energy and direction of neutrinos from the sun and other astrophysical sources such as supernovae. The unique feature is the use of heavy water which enables both electron neutrinos and all types of neutrinos to be measured. These measurements will provide sensitive tests of the standard solar model, vacuum oscillations and MSW effects. It will detect with high sensitivity all types of neutrinos from a supernova in our galaxy.
