Abstract

The SNO experiment has completed data taking for the last of three phases in which an array of ultra-low radioactivity 3He-filled proportional counters were deployed in the heavy water medium to observe neutrons from the neutral current reaction on deuterium. Data analysis is nearly completed and will provide a new independent measure of the neutral current reaction for 8B solar neutrinos with completely different systematic uncertainties from previous measurements. The new SNOLAB international underground science facility, expanding the experimental area 2 km underground, is nearly complete and will be ready for experiments this year. Brief descriptions of several experiments planned for this facility will be provided, including dark matter measurements by PICASSO, DEAP-1, Mini-CLEAN, DEAP/CLEAN and Super-CDMS; double beta decay measurements by SNO+ and EXO-gas and solar, geological, reactor and supernova neutrinos by SNO+ and HALO.
