OutlineOutline
Provide the foundational discoveries
R&D and EDR effort to make an “early” decision
Establish the foundations to be a host
Sustain the HEP accelerator based community for what could be a long march to the ILC

R&D + Engineering Design ReportR&D + Engineering Design Report
The next phase of ILC – aim for EDR in 2009-10 Provides detailed design and more accurate cost
– supported by results of R&D BIG ISSUE: how much site specific design gets
done in this phase? Limited by funding and international site determination
Big opportunity for Fermilab to contribute – strong engineering team
