Our group is an active member of the Sudbury Neutrino Observatory(SNO).
SNO consists of a one kiloton heavy water Cerenkov detector buried almost 2 km underground. The SNO experiment studies neutrinos that are produced in the nuclear reactions that take place in the solar core. In 2001, SNO was able to solve a 40-year outstanding puzzle in nuclear physics by observing that neutrinos from the sun oscillate from one type to the other.
As of November 28th, 2006, SNO took its last official data run.
The MIT group at SNO is involved in various analysis and calibration activities related to the last phase of the experiment (the NCD phase).
