  5. Schematic of the BCD SLAC SPC

  6. Baseline Configuration Document • Our ‘Deliverable’ by the end of 2005 • A structured electronic document • Documentation (reports, drawings etc) • Technical specs. • Parameter tables • Revisions and Evolution through Change Control Process http://www.linearcollider.org/wiki/doku.php?id=bcd:bcd_home SLAC SPC

  7. The Key Decisions Critical choices: luminosity parameters & gradient SLAC SPC

  8. Making Choices – The Tradeoffs Many decisions are interrelated and require input from several WG/GG groups SLAC SPC

  9. Parametric Approach SLAC SPC

  10. Baseline Configuration Document • Latest Official Version of BCD • BCD in MSWord files: • All-in-one-file • Single PDF File (2582kB, Updated Mar.28, 2006) • Single MSWord File (5103kB, Updated Mar.28, 2006) • By Area Nodes: • General Parameters (233kB, Updated Mar. 3, 2006) • Electron Source (296kB) • Positron Source (316kB) • Damping Rings (554kB, Updated Feb.27, 2006) • Ring to Main Linac (313kB, Updated Mar.28, 2006) • Main Linacs (455kB) • Beam Delivery (543kB) • TeV Upgrade Scenario (26kB) SLAC SPC

SLAC SPC

  12. Beam Delivery System • Baseline (supported, at the moment, by GDE exec) • two BDSs, 20/2mrad, 2 detectors, 2 longitudinally separated IR halls • Alternative 1 • two BDSs, 20/2mrad, 2 detectors in single IR hall @ Z=0 • Alternative 2 • single IR/BDS, collider hall long enough for two push-pull detectors SLAC SPC

  20. 2006 From Baseline to a RDR July Dec Jan Frascati Bangalore Vancouver Valencia Freeze Configuration Organize for RDR Review Design/Cost Methodology Review Initial Design / Cost Review Final Design / Cost RDR Document Design and Costing Preliminary RDR Released SLAC SPC

  21. Cost Roll-ups e- e+ damping RTML main BDS source source rings linac Area Systems SLAC SPC

  22. Damping Rings • Positrons: • Two rings of ~6 km circumference in a single tunnel. • Two rings are needed to reduce e-cloud effects unless significant progress can be made with mitigation techniques. • Electrons: • One 6 km ring. • COSTING • civil – tunnels • magnets • vacuum • etc SLAC SPC

  23. How to involve industry? • Large Scale Project Characterization • Large Project Management • Precision Engineering • International Coordination • Costing • Industrialization toward Fabrication • Civil Construction & Infrastructure • Cryogenics • Superconducting RF structures, couplers, etc • Electronics and Control Systems • Large Scale Computing SLAC SPC

  24. Global Design Effort • The baseline configuration for the ILC has been established and is document in the BCD (a 700+ page electronic document) • We have put the BCD under configuration control and are evolving it now in a controlled manner • The BCD also defines alternatives and the combination of the baseline and alternative will give good guidance for the ILC R&D program • The BCD is now being used as the starting point and basis for the reference design / cost effort this year. SLAC SPC

  25. International perspective Europe is conducting a long range plan of its particle physics program under aegis of CERN Council. Report due in July 2006. In 2003, Funding Agencies Linear Collider (FALC) was formed to help guide the international effort on ILC. FALC provides common fund for GDE activities. It is now beginning to take up issues of defining a site selection process, more formal oversight of the R&D phase, etc. The recent initialing of the ITER agreement establishing an international organization is an excellent template for the ILC.

  27. Funding Agencies for the Linear Collider • Seventh meeting held in Fermilab on 4 November 2005 • Representatives from CERN (President of Council and DG), Canada (NRC), France (CNRS), Germany (BMBF), Italy (INFN), Japan (MEXT), Korea (MOST), UK (PPARC) and the US (DOE) was held in Fermilab on 4 Nov 05 • The Group agreed that a Common Fund should be established to fund the administrative support required for the GDE ‘Phase-1’, with the costs to be funded equally by the three regions. The Group agreed that the use of this method of funding would not be used to prejudge the basis of any future agreements. It should only be applicable for the duration of this Common fund MOU for ‘Phase-1’. This Common Fund would be administered by Fermilab and be the subject of a MOU to be agreed by the FALC Resources group SLAC SPC

  28. Funding Agencies for the Linear Collider • The Group discussed the need to minimize duplication of reporting and increase communication between the current project structure and FALC. The Chairs of ICFA and ILCSC were invited to attend future meetings of the Group and the Chair of ILCSC was invited to attend future meetings of the FALC Resources Group. • It was agreed that a subgroup, consisting of members of FALC from all three regions, would consider the future mandate of FALC, its composition, the relationship with existing bodies required as the project moved to a more formal governance structure and mechanisms by which funds could be made available both before and after a site decision. • It was agreed that the next meeting would be held on 22 May 2006 in Rome.

  29. Creating an International Project • Several Studies and Plans for ILC • ECFA EUROPEAN COMMITTEE FOR FUTURE ACCELERATORS subcomittee EUROPEAN LINEAR COLLIDER STEERING GROUP • “Report of the Sub-group on Organizational Matters” • Features a detailed breakdown of top level governance and project management, how they relate to each other. It is based on regional organizations; mostly in-kind contributions; shared central management, oversight, responsibility. It is concerned with Europe and how to do it within European Labs (CERN) and structures SLAC SPC

  30. ECFA ILC Management Scheme SLAC SPC

  31. Creating an International Project • Many models of International Collaboration • ITER is the largest project, shared by six countries. There are both lessons learned and models of how to develop international project with agreed to costing, shared management, etc. Siting was a big problem • ALMA is a joint European, U.S. and Japan project with a shared management, mostly in-kind contributions, etc. Being a big array, it is straight forward to divide how many modules are contributed by partners and siting is not an issue. But, they have recently dealt effectively with management and cost issues. SLAC SPC
