      THE SUDBURY NEUTRINO OBSERVATORY: SALT ENHANCES THE NEUTRINO FLAVORS

                                   Abstract:
      The Sudbury Neutrino Observatory (SNO) is a 1,000 tonne heavy water
  Cerenkov-based neutrino detector situated 2,000 meters underground in INCO`s
    Creighton Mine near Sudbury, Ontario, Canada. Past measurements of solar
  neutrino fluxes have been smaller than predicted by solar model calculations
   (known as the Solar Neutrino Problem), implying that the calculations are
   incomplete or that some of the electron neutrinos produced in the sun are
changing to another flavor en route to earth. SNO has used the neutrinos from 8B
   decay in the Sun to observe one neutrino reaction sensitive only to solar
 electron neutrinos and others sensitive to all active neutrino flavors and has
found clear evidence for neutrino flavor change. Results from the multi-year SNO
observation program will be presented, including recent result with salt in the
         heavy water to enhance sensitivity to all active neutrino flav
