Deep Underground Science and Engineering Laboratory (DUSEL)
Davis CavernSep 21, 2009
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
Dark Matter searches
Long Base Line Neutrino Experiment & Proton Life time
Double Beta Decay Experiments
Homestake Homestake – Home to – Home to the Davis the Davis Detector Detector (Nobel (Nobel Prize, Prize,
Physics, Physics, 2002) 2002)
Raymond Davis, Jr.
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?

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 & core research
program:
NSF/DOE Collaboration
Interagency MOU planned for end of
FY 2010.

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

Project Status: Facility Design:
Design team at UC Berkeley and SD School of Mines has been completed and is making good progress on the preliminary design.
Experiments Design: Multiple collaborations have been formed (S4 awards) composed of
University and National lab teams to design a set of world class experiments for DUSEL lab.
Sanford Lab: Significant progress in dewatering 4850 Level infrastructure restoration underway
Safety Culture: Project team and Sanford Lab. developing a safety culture to allow for
a world class safe Laboratory. Preliminary Design expected end of CY 2010
