Reference Design Report

The draft report and associated cost estimate was presented to ICFA in Beijing

  • 11km SC linacs operating at 31.5 MV/m for 500 GeV

  • Centralized injector

    • Circular damping rings for electrons and positrons

    • Undulator-based positron source

  • Single IR with 14 mrad crossing angle

  • Dual tunnel configuration for safety and availability

Global Design Effort

Reference design cost estimate l.jpg
Reference Design Cost Estimate

  • The Value costs have been reviewed 3 times:

    • 3 day “internal review” in Dec 06

    • ILCSC MAC review in Jan 07

    • International Cost review in Orsay, Paris May 07

  • Σ Value = 6.62 B ILC Units

    • The technical design has been reviewed by the MAC

    • Also at the DOE ART review to a certain extent

  • The RDR & cost estimate + associated technical reviews has been formally presented to FALC 3 days ago (Rome) and will be presented to ICFA in August (Korea - Lepton Photon conference). This will end this phase of the project.


RDR “Value” Costs

Total Value Cost (FY07)

4.80 B ILC Units Shared


1.82 B Units Site Specific


14.1 K person-years

(“explicit” labor = 24.0 M person-hrs @ 1,700 hrs/yr)

1 ILC Unit = $ 1 (2007)

Global Design Effort

Ilc engineering design phase l.jpg
ILC Engineering Design Phase

  • We are at an evident change point in the ILC Project.

    • Two years after the formal formation of the GDE,

    • the recent completion of the draft Reference Design Report (RDR) marks a major milestone in this global effort.

  • The GDE is now in the process of restructuring itself and making plans for the engineering design phase, leading to the completion of the ILC Engineering Design Report (EDR) in 2010.

Global Design Effort

Engineering design phase will include l.jpg
Engineering Design phase will include:

  • Basic R&D to demonstrate that all components can be engineered

  • R&D into alternative solutions to mitigate remaining risk.

  • An overall design to allow machine construction to start within 3 years,

  • selection between high tech options must be made to allow industrialization efforts.

  • A comprehensive value-engineering exercise must be conducted.

  • A complete value cost estimate for the machine must be provided, including a funding profile consistent with the project schedule.

  • A project execution plan must be produced, including a realistic schedule.

  • Designs for facilities shared between different “area systems”, and for site-specific infrastructure. The designs must include the level of detail needed for regions to estimate the cost to host

  • All necessary information must be provided to regions to evaluate project technical and financial risks in support of a bid to host.

High priority controlling cost l.jpg
High Priority – Controlling COST

  • fundamental  containment of the current RDR Value estimate (no cost creep).

  • potential cost-reduction via engineering

    • clearly identified in the RDR (do we really need two tunnels ?).

  • Together with the risk-mitigating/cost reducing prioritised R&D program

    n.b. the Reference design costs were reduced by ~25% from the original numbers

Global Design Effort

Industrialization l.jpg

  • Second focus: increasing direct involvement of industries

  • Preparation for mass production

    • is a critical issue for key technologies,

    • understanding how individual countries can contribute in-kind

  • This must be achieved on a truly worldwide basis,

    • Intend to follow free-market

    • including seeking out and developing potential (new) industrial bases

      For example  India

Global Design Effort

Rdr provides guidance l.jpg
RDR provides guidance

  • The RDR provides a design and a value estimate that is parametric in nature,

    • allows us to identify the cost drivers and the technical risks;

    • critical in prioritizing both engineering and R&D,

  • primary cost drivers:

    • SCRF linac technology

    • CFS,

    • ~70% of the ILC value estimate.

  • These two will be a major focus during the EDR

Global Design Effort

Prioritization for the edr l.jpg
Prioritization for the EDR

  • Based on:

    • Technical risk mitigation

    • Cost risk mitigation

    • Cost reduction

    • Preparation

  • Not in the above order:

    • Quantitative evaluation possible based on RDR Value estimate and plan

  • Mechanism?

    • Define proposed Work Packages,

    • Build Work Breakdown Structure

    • Secure institutional/funding agency consensus

Reference design risk


Global Design Effort

Getting started on the edr l.jpg
Getting Started on the EDR:

  • Re-organize ourselves toward the EDR

    • Project management-based structure,

    • Definition, scope and resources

  • Examine RDR & plan EDR a starting point

    • Multi-day technical meetings planned

    • Internally controlled process

  • Continue the design work and technical R&D

Global Design Effort

Edr objectives main linac technology l.jpg
EDR Objectives – Main Linac Technology:

  • Complete the critical R&D as identified by the R & D Board task forces.

  • Coordinate/monitor industrialization efforts

  • Identify a plan for consolidating design work

  • Identify ways in which the maximum benefit can be obtained from the European XFEL project

    • Formally launched June 5, 2007

Global Design Effort

Edr objectives conventional facilities siting cfs l.jpg
EDR Objectives: Conventional Facilities & Siting (CFS)

  • CF/S has been identified as an RDR cost driver;

    • expected to yield cost reduction through “value” engineering.

  • Complicated via site/regional dependencies:

    • Need to delineate global/generic engineering and site/region-specific engineering;

    • Both categories to be clearly identified in WBS.

  • Primary EDR Goals:

    • iteration of CF/S requirements with accelerator designers/engineers (‘value engineering’);

    • Detailed evaluation of alternative solutions (e.g. shallow site);

    • Prepare critical information for specific site selection / development;

  • Lack of an agreed-upon single site is a significant problem

Global Design Effort

Edr objectives accelerator systems l.jpg
EDR Objectives: Accelerator Systems

  • Define performance-driven specifications for the accelerator components and infrastructure

  • Iterate cost/performance trade-offs

    • CF/S will be a focus;

  • Demonstrate that the accelerator design fulfills the required performance goals in a cost-effective way;

    • by demonstration via critical R&D;

    • by simulation;

  • Maintain a risk register, and develop alterative fall-back solutions.

Global Design Effort

Restructuring the gde l.jpg
Restructuring the GDE

  • Project Management for the EDR Phase

  • Devised along functional lines

    • (instead of institutional or regional…)

    • Many WP’s will have strong institutional center

  • Relationship between Project and Institutes through a series of ‘Memoranda’

  • Defines a Work Package for a given Institution

  • we must be extremely careful to develop and maintain inter-regional consensus/balance

  • Global Design Effort

    Ilc project management l.jpg
    ILC Project Management

    • Global focus

    • Role of the project managers in relation to the regional directors:

    • Project Managers are responsible for

      • Leading the worldwide technical development effort

      • Setting technical direction and executing the project toward realization of the ILC

    • Regional Directors are responsible for

      • Promoting, seeking funding and authorization of the international cooperative program.

    Managing a non centrally funded project l.jpg
    Managing a non-centrally funded project:

    • green indicates a commitment:

      • institute will deliver

    • MoUs facilitate connection:

      • Project Management (authority and responsibility) and institutions (funding and resources).

    • The ‘C’  coordinating role in a WP

      • Each WP has only one coordinator.

    Memoranda of understanding l.jpg
    Memoranda of Understanding

    • Until we have central funding, the GDE must continue to seek its resources indirectly via the institutes forming the collaboration.

    • Responsibilities for delivering a WP must be formally agreed upon between the GDE Project Management and the corresponding institute via MoU.

    • The institutes are then responsible for obtaining the necessary resources for the task from their funding sources (agencies).

    • The process by which the WPs are defined, and the allocation of institutes to carry out those WPs through MoUs, must be an open and transparent process allowing all interested parties to make a proposal to carry out the work and to understand and accept the criteria used in decision making.

    Global Design Effort
