    • Your plans for how to make progress on the LC design and R&D.

P5 Meeting - Washington DC


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).

P5 Meeting - Washington DC


Starting Point for the GDE

Superconducting RF Main Linac

P5 Meeting - Washington DC


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.

P5 Meeting - Washington DC

    Design approach
    Design Approach 2010

    • 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 2010

    • 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 2010

    • 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
