An international initiative
An International Initiative

  • R&D toward an ILC was carried out over the last decade in three regions of the world and primarily at SLAC in the U.S., KEK in Japan and DESY in Germany

  • The crucial technology decision was successfully made by an international panel having 4 members from each region

  • We are now entering the design phase, which will be carried out under the guidance of the GDE, which again has comparable membership from all three regions

  • We fully expect the final project to be international

The technology recommendation
The Technology Recommendation

  • The recommendation was presented to ILCSC & ICFA on August 19 in a joint meeting in Beijing.

  • ICFA unanimously endorsed the ITRP’s recommendation on August 20

The global design effort
The Global Design Effort

  • The Mission of the GDE

    • Produce a design for the ILC that includes a detailed design concept, performance assessments, reliable international costing, an industrialization plan , siting analysis, as well as detector concepts and scope.

    • Coordinate worldwide prioritized proposal driven R & D efforts (to demonstrate and improve the performance, reduce the costs, attain the required reliability, etc.)

Ilc siting and conventional facilities
ILC Siting and Conventional Facilities 2010

  • The design is intimately tied to the features of the site

    • 1 tunnels or 2 tunnels?

    • Deep or shallow?

    • Laser straight linac or follow earth’s curvature in segments?

  • GDE ILC Design will be done to samples sites in the three regions

    • North American sample site will be near Fermilab

    • Japan and Europe are to determine sample sites by the end of 2005

Fermilab ILC Industry Meeting


1 vs 2 tunnels
1 vs 2 Tunnels 2010

  • Tunnel must contain

    • Linac Cryomodule

    • RF system

    • Damping Ring Lines

  • Save maybe $0.5B

  • Issues

    • Maintenance

    • Safety

    • Duty Cycle

Possible tunnel configurations
Possible Tunnel Configurations 2010

  • One tunnel of two, with variants ??

Fermilab ILC Industry Meeting


Ilc civil program
ILC Civil Program 2010

Civil engineers from all three regions working to develop methods of analyzing the siting issues and comparing sites.

The current effort is not intended to select a potential site, but rather to understand from the beginning how the features of sites will effect the design, performance and cost
