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 meritand technical feasibility

White Paper Description in Progress
Excavation has begun under contract with Redpath
First new space in about 1 year
Laboratory complete in 2007
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
Provide support for underground program– Clean assembly, – lab space – meeting rooms,– Computing facilities– Office space
