SNOLAB – An International Facility for Underground Science Expand underground space to allow several experiments to operate simultaneously Provide a surface building to support the underground experiments Experiments selected on the basis of scientific merit and technical feasibility IX International Conference on « Neutrino Telescopes » Venice, 23 February 2005 V. Zacek Université de Montréal

Features of underground space All space within a common clean boundary (~class 2000) Common infrastructure includes dirty-clean transition and materials handling, power (~1.5 MW), cooling (300 T), water, UPW, networking (Gb/s off site, high speed internal) and clean ventilation system Design allows for future expansion but scale is limited
