Next Goal – Reference Design Reorganized the GDE toward Design / Cost Effort A global effort to design / cost the ILC is underway and working Configuration Control; International Costing; Industrialization; Siting -------------------------- A sound design must be established with convincing and affordable costing. Review and guidance for the Global R&D program to demonstrate the ILC, improve over the baseline and reduce costs. 20 April 06 P5 - SLAC Global Design Effort

Elements of the ILC R&D Program R&D in support of the BCD 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. Guidance from Change Control Board Develop a prioritized DETECTOR R&D program aimed at technical developments needed to reach combined design performance goals 20 April 06 P5 - SLAC Global Design Effort

Global R&D Board (RDB) The Global R&D Board will be responsible for assessing and providing guidance for the overall R&D program.  The RDB will suggest priorities for the research facilities and R&D supporting the baseline, the R&D on alternatives to the baseline and selective R&D that could further the field in the longer term.  The mission will also include global assessments and recommended priorities for the detector R&D program and evaluate the balance between accelerator and detector R&D. The RDB will develop a proposal driven program, structured in the sense of defined goals, and milestones, and resources evaluated on a common basis to allow comparison across different regions and national funding systems.  It will conduct reviews and identify gaps in coverage of topics, resource or technical issues, duplications, and other concerns.. 20 April 06 P5 - SLAC Global Design Effort

Mission of the Global R&D Board Coordinate worldwide, prioritized, proposal- driven, R & D efforts The goal is clear, the detailed means required resolution by the RDB of issues, for example: Level of coordination Parallel efforts coordination, Regional needs “Reviewing” role: Ideal vs specific R&D Program Balance ILC/ILC Detectors issues Goals, Timelines Interfaces, RDB/DCB, RDB/Industrialization… 20 April 06 P5 - SLAC Global Design Effort

RDB Plan for Achieving its Mission First tackle work that leads to immediate benefits Project Tools to allow a Work Breakdown structure to put all Global R&D on a common basis, needs: A Data Entry Tool A Data Base with flexible features A facility for generating needed Reports CERN has kindly agreed to help us with the Data Base and Reports, and our Board member Eckhard Elsen agreed to be Data Integrator to make the system work Generate an Ideal ILC Research Program 20 April 06 P5 - SLAC Global Design Effort from Willis

Ideal ILC R&D Program Generate WBS for ten ILC Areas (no Cryogenics R&D identified for the Baseline), with about 400 items The structure will allow us to note links items in different Regions Assign Priorities 1 (very high), 2 (high), 3 (moderate), 4 (low) by team of two Board members per area, with justification Reviewed anonymously by all members, with comments Discussion of board to reach conclusion Face to face meeting to consider uniformities among areas 8 March “Last” iteration took place this week Publication (RDB Public Wiki) took place this week http://www.linearcollider.org/wiki/doku.php Convenient Reports will be created from the data base at CERN soon, useful for example for Dugan 2007 meeting in May 20 April 06 P5 - SLAC Global Design Effort from Willis
