- Strong collaboration ANL, Illinois Universities
- Special role of University of Chicago
- URA R&D funds to strengthen Universities-Fermilab ties

## Working with the Community

- Envoy Program
- Citizen’s Task Force
- Outreach to many groups
- Publications

## The importance of the RDR

- Secretary Bodman: How much ?
- Answer =
-    (1.8B +4.9B) ILCus
-     +13 kFTEs
-     + detector(s)
- Consequence: continue vigorous R&D and be cautious about time frame

## The golden “moment”

**LHC discoveries**

**US facilities shutdown**

**Regions agree**

**ILC**

**2010**

**Site selected**

## Quadruple coincidence may not happen

**LHC discoveries**

**US facilities shutdown**

**Regions agree**

**Site selected**

**2010**

**ILC**

## Then what?

- Accelerator activity greatly reduced in 2010
- ILC activity limited before decision to build
- ILC R&D could integrate to too much $ (standing army problem)

## The problem to solve

- How to sustain ILC activities over a possibly longer period before decision to build
- How to create alternative discovery opportunities that might be needed
- I am establishing steering group with broad participation under Young-Kee Kim to generate strategic plan for accelerator program
