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

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 ‘Phase1’, 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

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 inkind 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.
