2. Henderson DUSEL November 2005 2 Topics Interaction between science requirements & conceptual design Top design issues Status of some design issues Top collaborative issues Action plan & milestones

3. Henderson DUSEL November 2005 3 Interaction Between Science Vision & Conceptual Design What are we designing and why? Iterative process Regular communication Documentation WBS Design Criteria Program

4. Henderson DUSEL November 2005 4 Top Design Issues Conceive a facility for doing great science Fire & life safety (FLS) Integration with Henderson facility Timeline issues Laboratory development plan Infrastructure development plan Operations & construction phasing Experiment descriptions

5. Henderson DUSEL November 2005 5 Draft Lab FLS Concept (during mining)

6. Henderson DUSEL November 2005 6 Lab vs. Infrastructure Development Plan

7. Henderson DUSEL November 2005 7 Design Life Criteria for Infrastructure Suggested initial design life (capacity only) Lab life—30?, 40?, 50? years Drift cross section—sized for full expansion Duct size—20 years Power conductors—20 years Power transformers—10 years Chiller piping—20 years Chiller plant—10 years Communications—10 years

8. Henderson DUSEL November 2005 8 Physics experiment power requirements

9. Henderson DUSEL November 2005 9 Top Design Issues (cont.) Modules & module relationships Access concept Access size Underground layout Facility size, cost target Cleanliness Common facilities Operating strategy & criteria Surface facilities

11. Henderson DUSEL November 2005 11 Draft Lab Drift Cross Section

12. Henderson DUSEL November 2005 12 Top Collaborative Issues Scientists must: have a vision convert vision to facility characteristics Engineering team must: develop strong documentation WBS Design criteria Program Visual not hinder science while keeping the plan realistic

13. Henderson DUSEL November 2005 13 Vision & Design Criteria Workshop Conducted in October 2005 Some results General consensus on the laboratory destinations & access Considered access alternatives Clean suite required in Central & Lower campus Conceptual plan for FLS regulatory responsibility Others

14. Henderson DUSEL November 2005 14

15. Henderson DUSEL November 2005 15 What do the designers need from you? Consensus on science vision & needs Laboratory research destinations Access Infrastructure needs Initial suite Relationship needs 10 thru 30+ year vision When?

16. Henderson DUSEL November 2005 16 Action Plan & Milestones Vision & Design Criteria Workshop, past Physics & Geosciences Workshops, now “Inception Report”, a week or two Questionnaires, next week Mining & Engineering Workshop, December Feedback on layout & infrastructure needs from physics & geosciences by 12/15, final by 1/15 Ditto from mining & engineering group by 12/31, final by 1/31

17. Henderson DUSEL November 2005 17 Discussion & Questions?

18. Henderson DUSEL November 2005 18 Relationships Assumptions Physics separations Accelerator module separate from (most?) other physics Deep, clean, low background module separate from large & intermediate depth physics modules Modules separate from all other activities Restricted access module Remote very large block / reservoir scale experiments Large block, highly perturbed Large block, pristine experiments Drift structure experiments

19. Henderson DUSEL November 2005 19 DUSEL Layout Access points No. 2 shaft Various levels Ore tunnel & portal Research destinations Upper campus (8100 shop) Central campus Lower campus Experimental mine Geoscience outposts, pristine) Geoscience outposts, perturbed Bioscience outposts Sampling Deep drilling

20. Henderson DUSEL November 2005 20 DUSEL Layout Various starting points Various ending points About 29,000 ft of drifting How should this be drifting be used to gain access for earth science?
