ILC, the Door to a Scientific Revolution
• Findings in the past years still lead us to many leading
questions (suggesting low SM higgs mass, TeV Scale Physics,
possibly with SUSY, dark matter, dark energy, extra
dimensions, etc.)
• While we have many remarkable theoretical models, we need
more comprehensive understanding of what we observe
• We need the experimental tools now or in the near future to
make the discoveries
• In 2007 LHC will turn on. With its great discovery potential,
the LHC probably lay the foundation of our understanding
• The LHC alone will not suffice to unlock all the mysteries.
ILC will take additional tools to make the complementary
discoveries needed to sharply and fully understand our
ILC: the Energy Frontier Machine
Enormous Strides toward ILC
• The HEP community has made enormous
strides this past year, both in the
accelerator and detector arenas, towards
realizing a unified, international design for
the ILC
– ICFA (with ACFA, ECFA, US) established
ILCSC in 2002
– We have a Very Active ILCSC
Concepts of GDE/GDI/Organization
LC Parameters (Sep 2003)
Cold Technology (ITRP, Aug 2004)
1st ILC Workshop (Nov. 2004)
GDE Director (Feb, 2005)
Global Design Effort (GDE)
• On March 18, 2005
Barry Barish officially
accepted the position
at the opening of LCWS
05 meeting at Stanford
• Barry reported the
GDE plan at this ACFA
• Now we also have a new
ILCSC Chair, Prof. Sinichi Kurokawa.
• Congratulations !
From Governments and
Funding Agencies side
• OECD – Global Science Forum launched th
Consultative Group on HEP and accepted its report
on HEP Roadmap, etc. (2002)
• OECD Ministerial Meeting (Jan 2004) adopted
statements on LC as a next collider machine,
emphasizing the importance of global R/D efforts,
manpower raising-up, and early discussions among
government agencies
• Funding Agencies for LC(FALC) meetings began
2003 and started discussion on MoU and Site
– Asia partners (Japan, Korea, India) joined (2004)
– FALC established FALC-Resource Group (Feb. 2005)
• Expect More Activities in coming years
GDE Director’s View and Plan
Technically Driven Schedule
• Near Term Plan
– Staff the GDE
Total staff size about 20 FTE (2005-2006)
– Organize the ILC effort globally
• First Step --- Appoint Regional Directors within the GDE,
Make Website, coordinate meetings, coordinate R&D
programs, etc
– R&D Program
• Coordinate worldwide R & D efforts, (Proposal Driven to GDE)
Near Term Plan (GDE)
• Schedule
• Begin to define Configuration (Aug 05)
• Baseline Configuration Document by end of 2005
----------------------------------------------------------• Put Baseline under Configuration Control (Jan 06)
• Develop Reference Design Report by end of 2006
• Three volumes -- 1) Reference Design Report; 2)
Shorter glossy version for non-experts and policy
makers ; 3) Detector Concept Report
The GDE Plan
The Machine
Accelerator baseline configuration will be determined and
documented (BCD) by the end of 2005
R&D program and priorities determined (proposal driven)
Baseline configuration will be the basis of a reference design
done in 2006
The Detector(s)
Determine features, scope: one vs two, etc (same time scale)
Measure performance of the baseline design
Beam delivery system and machine detector interfaces
Define and motivate the future detector R&D program
Now, ILC on its Vehicle
• The results of studies presented and summarized
at this workshop will provide very sound inputs to
the Global Design Efforts (especially to the 2nd
ILC Workshop and Snowmass)
• This workshop also had discussions on accelerator
/ Machine Detector Interface (MDI) issues (new
approach and very productive)
• GDE Director wants Detector/Physics staff in
Central/Regional Teams
• Welcome this kind of very cohesive approach to
ILC Design
ILC, a New Truly Global
Project / Lab
• It is very important that not only the ILC efforts but also a
(existing or new) Lab hosting ILC should be truly GLOBAL
and INTERNATIONAL in order for the ILC to be realized
• So is the G(lobal) D(esign) E(fforts)
• The Regional Efforts within Asia should be truly multilaterally international
• To be so, it is highly desirable to keep this spirit among us
and to show it to public during the courses of efforts even
though there are a very big gaps and differences in the
levels of understanding and supports and wide range of
rationale among Asian countries
• Nevertheless, we should NOT forget that ILC physics to be
pursued should be emphasized with the highest priority
among us and to the public
Messages from OC and
Plan of Activities in Asia
Based on discussion among members of ACFA, ALCSC, ICFA,
Asian Regional Team, and ACFA LC Workshop OC
 Let us make an MOU among Asian institutes and interested parties
(for a realistic level, starting from groups in University, labs, etc)
Regarding regional activities for general aspects for ILC
physics and detector R&D,
accelerator R&D
and outreach to various societies and bodies.
This will be a basis to secure R&D budgets from many resources and
Continue regular meeting among Asian members of ACFA,
ALCSC, ICFA, Regional team headquarters, ACFA OC.
A teleconference meeting before Snowmass,
then a face-to-face meeting at Snowmass.
Urgent tasks
A very urgent task is to identify active contact persons (3-4?) and
outreach experts in each country.
An important target is to form the MOU above.
Draft to propose structure of regional GDE.
Draft to propose (request) what role, what to do, authority of
regional director.
Long term—
Seek ways to get budgets and expand outreach.
 Outreach group
First task: GLC executive summary  translate to each local language.
Translation of web page made by GDE.
1-2 page pamphlet.
 An idea-----To Organize `Council`
consisting of High level persons,
discuss founding/human resource
advice regional team, ACFA,
Contact governments together with GDE, regional GDE, ALCSC, ACFA.
 Next ACFA workshop-----China or Japan.
Avoid too many meeting, but regional meetings are important.
Hopefully to be decided by the time of Snowmass meeting.
The next ACFA LCWS
Korea  This workshop
Japan or China
