Barry Barish GDE Meeting Frascati 7-Dec-05 Introduction and Charge
The GDE after ~3 Months • How are we doing? • BOTTOM LINE is that we are on track to produce a BCD by end of 2005 that will provide a sound basis for entering into a reference design effort, globally coordinate R&D program, begin industrialization, determine costs, etc. next year • What are our biggest problems? • communication, communication, communication • Where are we going next? • Stay tuned for my next talk GDE Frascati - Introduction & Charge
GDE Frascati – Why are we here? • Discuss progress since Snowmass • Finish the BCD • Organize the GDE and the broader R&D and Design efforts for next year GDE Frascati - Introduction & Charge
GDE Began at Snowmass 670 Scientists attended two week workshop at Snowmass GDE Frascati - Introduction & Charge
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.) GDE Frascati - Introduction & Charge

Goals of the Snowmass Workshop • Recommendations for the Baseline Configuration • Identify - Alternative Configurations • Identify R&D • To support the baseline • To develop the alternatives • Priorities for detector R&D GDE Frascati - Introduction & Charge
Guidance for Baseline Configuration Baseline: A forward looking configuration which we are reasonably confident can achieve the required performance and can be used to give a reasonably accurate cost estimate by mid-end 2006 in a “Reference Design Report.” GDE Frascati - Introduction & Charge
What are Alternatives and Why? Alternates: Technologies or concepts, which may provide a significant cost reduction, improved performance (or both), but which will not be mature enough to used in baseline by end 2006Alternatives will be part of the RDR, will form an important element in the R&D program and are the key to evolving the design GDE Frascati - Introduction & Charge
Baseline Configuration Document • Our ‘Deliverable’ by the end of 2005 • A structured electronic document • Documentation (reports, drawings etc) • Technical specs. • Parameter tables • … • A ‘printable / readable’ summary document (~100 pages) (ready in early 2006) GDE Frascati - Introduction & Charge
Structure of the BCD Summary-like overview for those who want to understand the choice and the why Technical documentation of the baseline, for engineers and acc. phys. making studies towards RDR GDE Frascati - Introduction & Charge
Alternatives Section(s) NoteACD is part of the BCD GDE Frascati - Introduction & Charge
The Key Decisions Critical choices: luminosity parameters & gradient GDE Frascati - Introduction & Charge
Making Choices – The Tradeoffs Many decisions are interrelated and require input from several WG/GG groups GDE Frascati - Introduction & Charge
From Snowmass to a Baseline 2005 Snowmass August September October November December WW/GG summaries Response to list of 40+ decisions All documented ‘recommendations available on ILC Website (request community feedback) Review by BCD EC BCD EC publishes‘strawman’ BCD BCD Executive Committee: BarishDugan, Foster, Takasaki Raubenheimer, Yokoya, Walker Public Review Frascati GDE meeting GDE Frascati - Introduction & Charge
Baseline Configuration Document Review Process • BCD executive committee has monitored BCD progress • Review WG/GG summary write-ups (recommendations) • Review each question on the list of 40+ decisions • BCD EC identified and solicited needed additional input • Commissioned 5 “white papers” • Invited independent reviewers (Oide, Richter & Rivkin) • Strawman BCD available mid-November • Presentation of strawman BCD at Frascati GDE meeting (Dec. 10-12) • Final agreed BCD to be documented by end of 2005 • Final BCD becomes property of ‘Change Control Board’ in early 2006 • Reference Design to be completed by end of 2006 GDE Frascati - Introduction & Charge
The Prospects for the ILC • The science motivation for the ILC is our strongest weapon • The technical basis for the ILC is very stong • A global effort to design the ILC is underway and working • Establishing a baseline will make the ILC more real and taken more seriously -------------------------- • A sound design must be established with convincing and affordable costing. • Global R&D program to demonstrate the ILC, improve over the baseline and reduce costs.
