what s our job
What’s our job?
  • 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.)

P5 Meeting - Washington DC

the itrp recommendation
The ITRP Recommendation
  • We recommend that the linear collider be based on superconducting rf technology
    • This recommendation is made with the understanding that we are recommending a technology, not a design. We expect the final design to be developed by a team drawn from the combined warm and cold linear collider communities, taking full advantage of the experience and expertise of both(from the Executive Summary).

parameters for the ilc
Parameters for the ILC
  • Ecm adjustable from 200 – 500 GeV
  • Luminosity ∫Ldt = 500 fb-1 in 4 years
  • Ability to scan between 200 and 500 GeV
  • Energy stability and precision below 0.1%
  • Electron polarization of at least 80%
  • The machine must be upgradeable to 1 TeV

P5 Meeting - Washington DC

higgs coupling and extra dimensions
Higgs Coupling and Extra Dimensions
  • ILC precisely measures Higgs interaction strength with standard model particles.
  • Straight blue line gives the standard model predictions.
  • Range of predictions in models with extra dimensions -- yellow band, (at most 30% below the Standard Model
  • The models predict that the effect on each particle would be exactly the same size.
  • The red error bars indicate the level of precision attainable at the ILC for each particle
  • Sufficient to discover extra dimensional physics.

design approach
Design Approach
  • Create a baseline configuration for the machine
    • Document a concept for ILC machine with a complete layout, parameters etc. defined by the end of 2005
    • Make forward looking choices, consistent with attaining performance goals, and understood well enough to do a conceptual design and reliable costing by end of 2006.
    • Technical and cost considerations will be an integral part in making these choices.
    • Baseline will be put under “configuration control,” with a defined process for changes to the baseline.
    • A reference design will be carried out in 2006. I am proposing we use a “parametric” design and costing approach.
    • Technical performance and physics performance will be evaluated for the reference design

P5 Meeting - Washington DC

parametric approach
Parametric Approach
  • Parametric approach to design
    • machine parameters : a space to optimize the machine
    • Trial parameter space, being evaluated by subsystems
    • machine design : incorporate change without redesign; incorporates value engineering, trade studies at each step to minimize costs

P5 Meeting - Washington DC

approach to ilc r d program
Approach to ILC R&D Program
  • Proposal-driven R&D in support of the baseline design.
    • Technical developments, demonstration experiments, industrialization, etc.
  • Proposal-driven R&D in support of alternatives to the baseline
    • Proposals for potential improvements to the baseline, resources required, time scale, etc.
  • Develop a prioritized DETECTOR R&D program aimed at technical developments needed to reach combined design performance goals

ILC Siting and Conventional Facilities
  • 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

P5 Meeting - Washington DC

ilc civil program
ILC Civil Program

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

industrial studies
Industrial Studies
  • Industrial studies in three regions are essential.
    • Important to understand industrial costs
    • Important to examine potential cost reductions
    • Need to think about what studies are needed and when
    • Focus on the cost drivers for ILC, important for cost estimate
    • Focus on places where there is technical risk to the project goals
    • ILC need a point-of-contact and a plan for industrial studies

Detector Concepts and Challenges

  • Three concepts under study
  • Typically requires factors of two or so improvements in granularity, resolution, etc. from present generation detectors
  • Focused R&D program required to develop the detectors -- end of 2005
  • Detector Concepts will be used to determine machine detector interface, simulate performance of reference design vs physics goals next year.
