The Key Decisions

Critical choices: luminosity parameters & gradient

5 May 06 SLAC SPC 8

Making Choices – The Tradeoffs

Many decisions are interrelated and require input from several WG/GG groups

5 May 06 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

5 May 06 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

5 May 06 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.

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.

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

5 May 06 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.

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

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.
