Deep Underground Science and Engineering
Laboratory (DUSEL)

• DUSEL is being envisioned as a unique, dedicated
  international underground education research
  facility that would support potentially
  transformational experiments in multiple
  disciplines
• The U.S. particle, nuclear, and astrophysics
  communities have selected DUSEL as central to
  their national programs
• The engineering, geology and biology communities
  are proactively engaged, and participate in all
  aspects of DUSEL planning
• Development focused on the former Homestake Gold
  Mine (Lead, SD), the deepest mine in North
  America

Cosmic Questions for DUSEL

• Of what is the Universe made?
• What is Dark Matter?
• What are neutrinos telling us?
• Are protons unstable?
• Where did the antimatter go?
• How did the Universe evolve?

Proposed Science in DUSEL

• Four main pillars of emerging national physics
  program
• Long Baseline ? experiment
• Proton Decay
• ßß decay
• Dark Matter
• Other programs (list growing as possibilities
  become known)
• New capabilities in nuclear and neutrino
  astrophysics
• Research in geology, chemistry, biology,
  atmospheric sciences!

NSF/DOE Collaboration

• NSF/DOE agreed to establish DUSEL Physics Joint
  Oversight Group (JOG) immediately after release
  of P5 report (May 2008).
• Will jointly coordinate oversee DUSEL
  experimental physics program.
• JOG meeting bi- monthly.
• Both agencies closely collaborating in defining
  and realizing the DUSEL physics program.
• Agencies have agreed on DUSEL stewardship roles

International Opportunities

• Open Global Laboratory
• NSF would steward DUSEL for the world community
• Experiments and collaborations welcome
• International partners assume only incremental
  costs
• Infrastructure investment already made
• Network of similar labs around the world?
• Coordinated, distributed global program
• Cooperative stewardship model
• For multi-component scope (not, e.g., ITER)
• Well defined steward co-sponsor roles
• Well defined extent of risk
• Extend JOG concept as appropriate

Summary

• DUSEL Scientific Promise and Project Status
• Potentially transformational over a decade in
  planning
• Solid technical trajectory towards Preliminary
  Design Review in early 2011
• Timelines and key decision points
• Establish baseline late 2011
• Final Design Review mid-2013?
• Construction start 2014?
• International Opportunities
• Partners in facility definition Partners in
  discovery
• Broad scientific scope
