B.Sadoulet Boulder Intro 1/5/05 1 Boulder DUSEL Study Workshop Introduction Apologies: a difficult date! The DUSEL Process The DUSEL (Solicitation 1) Study Goals of this 3rd workshop Bernard Sadoulet Dept. of Physics /LBNL UC Berkeley UC Institute for Nuclear and Particle Astrophysics and Cosmology (INPAC)

B.Sadoulet Boulder Intro 1/5/05 2 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, submitted on Sept 15, 2004 ( Unofficially approved by NSF (with 20% budget reduction) PIs 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?)

B.Sadoulet Boulder Intro 1/5/05 3 Solicitation 1 Organization 6 PIs 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 PIs 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

B.Sadoulet Boulder Intro 1/5/05 4 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 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 in particular bring in evolutionary molecular, cell and microbial biologists + new ideas Focus on infrastructure requirements -> Modules Progress is important for Solicitation 2 proposals Place DUSEL in international context: unique aspects Launch work of the working groups infrastructure and writing assignments Washington Area: May or June Preliminary conclusions First draft of report

B.Sadoulet Boulder Intro 1/5/05 5 Berkeley Workshop: A Powerful Case for DUSEL Unique aspects Earth Sciences: Deep, long term is unique Physics: Depth ? Long baseline + 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 SNO Japan/Europe

B.Sadoulet Boulder Intro 1/5/05 6 Blacksburg workshop: The Big Earth Science Questions The conditions for life Limits Metabolism/ Energy source Evolution/Ancient life The everchanging 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 Climate change ? Paleoclimate ? Ancient sequestered water Clouds? Note: Not a division between biologists and geologists. Each of these two themes need the whole complement of expertise

B.Sadoulet Boulder Intro 1/5/05 7 Blacksburg workshop: Some useful syntheses Science, methods and applications:complementary facets Ex: The ever changing earth, observation methods (“transparent earth”) and the origin/discovery/exploitation of resources Overlap is testimony of the richness of the field Opportunity for multiple advocacy (NSF-DOE- Congress - Industry) Earth science is not geology independent Not everything can be done at every site What are the generic site characteristics which are necessary to at least start to tackle the most important questions cf Depth as a major characteristic for physicists (but not needed for all) Do we have enough of a scientific case for recommending eventually a combination of sites with a variety of rocks :Sedimentary + hard rock +salt? Elaborate roadmaps using complementarity e.g. from simplest to more complex comparison low/high porosity, carbon rich--hydrogen rich

B.Sadoulet Boulder Intro 1/5/05 8 Goals The most powerful arguments for DUSEL The big questions A short list compelling both for the specialist and the public at large We will not justify DUSEL with a large collection of B projects. A few essential (A+) projects, which may enable useful (B) projects. Unique aspects of a US DUSEL Understand better the international situation: what exists, visions, plans What are the unique aspects? How is it complementary? Partnerships Strategic arguments A good generic plan for implementation Roadmap of high priority generic experiments Infrastructure requirements for these experiments and laboratory as a whole +management Modules: saving on common infrastructure synergies possibility of phased implementation Realism: Watch cost/complexity : we can very effectively kill the project! Make as much progress as possible here.Solicitation 2 Define work for the working groups this winter
