DUSEL Process
Solicitation 1: Community wide study of
• Scientific roadmap: from Nuclear/Particle/Astro Physics to Geo
Physics/Chemistry/Microbiology/Engineering
• Generic infrastructure requirements
• Proposal supported by all 8 known sites (www.dusel.org)
Approved by NSF (with 20% budget reduction)
PI’s will go to Washington in February to clarify goals and time scale
Solicitation 2 : Preselection of 3-5 sites
• Proposals due February 28.
Solicitation 3
Selection of initial site(s)
MRE and Presidential Budget (08?) -> 2010

Solicitation 1 Organization
6 PI’s responsible for the study
in particular scientific quality/ objectivity
14 working groups + Workshops
Infrastructure requirements/management
Education and outreach
2 consultation groups
• The site consultation group (Solicitation 2 sites)
Endorsement of the PI’s and general approach
Input on scientific/technical questions important to the sites
Competition between sites
• The initiative coordination group: major stakeholders (e.g. National
Labs)
Coordination with other major initiatives
Competition between these initiatives
Report directed at OMB/OSTP/Congress
cf. Quantum Universe
+Web based reports
with technical facts
External review à la NRC

Workshops
Berkeley Aug 4-7
Agree about methodology and finalize Solicitation 1 proposal
First exploration of scientific themes
Start of work on infrastructure requirements
Common language for solicitation 2
Blacksburg Nov 12-13
Focus on Earth Sciences (including Geo-microbiology) and Applications
More precise definition of scientific roadmaps and generic experiments
Boulder Jan 5-7:
Further develop the science argument for DUSEL
Focus on infrastructure requirements -> Modules
Place DUSEL in international context: most unique aspects
Launch work of the working groups
Washington Area: Early June
Preliminary Conclusions
First draft of report

A Powerful Case for DUSEL
Unique aspects
Earth Science: Deep, long term is unique
Physics: Depth
Long base line + accelerators
Likely demand and evolution of science
We have to build the case
Road maps + Infrastructure requirements
Strategic importance
- as large scale experiments become international , important to
have US site to have US teams leading the projects
- We want the U.S. to be a leader in geoscience techniques
- Energy sciences (finding oil deposit, etc.)
- Underground construction
- Education of our scientists and engineers
- Homeland security
International context and partnerships

The Big Earth Science Questions
The conditions for life
How do the underground microbes manage to live in such an environment
What can we learn from the microbes underground
What can we learn about evolution and ancient form of life
The ever changing earth
Behavior of rock and fluids at depth.
Coupled processes in inhomogeneous media: mass, momentum,energy flow
Spatial and temporal scaling “laws”
The structure and the evolution of the earth
Observing from inside out: Core/mantle/crust/mountain
Dynamics: earthquakes
The concentration of ore deposits

Strategy
Importance of the science: identify key projects
Physics: Neutrinos/Dark Matter/Stability of matter
Biology
Earth science
This science is international
Large cavity detector for proton decay/ neutrino
After 100kg stage of double beta decay/dark matter, ton scale, largeTPC
Need for the US
Eventually we need a national facility
Strategic advantage
At the core of major physics experiments
A unique facility for deep earth science and microbiology
Training of the next generation of geoscientists
Support of national program
Flexibility
This is experimental science, not an observatory
Decoupling of large detector from deep science
($1.5B)= megascience decision taken
Long Base Line + Proton decay: Science + politics less mature
But a US deep site able to accept also large detector: competitive advantage
Although some advantages of a single site, not necessary (+earth science)
Role of SNOLab: saves us in the short term, evolution in the long term

DUSEL & CDMS
Too late for SuperCDMS
-> SNOLab
Impact on long term evolution
Positive impact
General
Importance of Physics of the Universe
Significant investment -> capture the attention of the administration/Congress
Unification of the community + collaboration with earth scientists and biologists
International consultation
Need for R&D
Dark Matter Study Group (Dan Akerib, Elena Aprile)
Dialogue between the dark matter groups
Enhance visibility in the community of the 150 kg- ton scale dark matter
Low Background Counting Study Group (Prisca Cushman, Harry Miley)
But
Better argument for the need for counting facilities
Long term
Lots of work (both scientific and political)
