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

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

6

• Provide support for underground program
• Clean assembly,
• lab space
• meeting rooms,
• Computing facilities
• Office space

7

• Building Ready end of May, 2005
