As part of its nuclear reactions in its core, the sun produces                  neutrinos.  Neutrinos are electrically neutral particles that                   interact only very rarely with matter.  Once produced, they pass                through the sun and fly off into space.  The Principal                          Investigator (PI) of this proposal intends to measure the solar                 neutrino flux on earth, making use of new fast counting equipment               and of chlorine, which becomes excited when absorbing neutrinos                 and thereby allows the measurement of the rate of solar neutrino                absorption.  This is a classic neutrino experiment that the PI                  has been conducting for about two decades in the Homestake Gold                 Mine.  The ultimate goal of this experiment is to understand the                current differences between the measured and theoretically                      predicted solar neutrino flux.
