The goal of ILC is to answer fundamental questions of Nature, which have been challenged for more than 2000 years.

Innovative instruments, such astelescope, microscope, and accelerator, have caused revolution in science.

Standard Model of Particle Physics

LHC: 2008 〜

ILC: 20XX 〜

NOW

Beyond Standard Model20th century started with science revolution;relativity and quantum theory.

Now the Standard model is good.However, Higgs is missing, No gravity, No unification of forces, No explanation for neutrino mass, dark matter/dark energy

Explorer TeV scale origin of mass (=vacuum) new space-time symmetry extra dimensions ….

How do we challenge these long-standing questions ?

Our target is TeV scale.

One country cannot do everything at one time !

We need to prioritize projects considering science merit.

The energy frontier (TeV scale) is most important.e.g. EPP2010 (NAS-USA), Strategy document (CERN) JAHEP report (Japan)

However, an energy frontier machine is most expensive.

Global cooperation is ‘a must’ for a next-generation frontier accelerator, which is ‘a must’ for exploring TeV scale.

A case of KEK ...

A well-balanced program should be developed in each country/region; participation to a global project and promotion of national projects.

Roadmap -HEP-

• According to the JAHEP community’s master plan,– Highest priority is given to ILC– Before ILC, promote flavor physics at KEKB and J-PARC

• Action before the ILC approval– ILC R&D– Completion/commissioning of J-PARC

• Considering the world competition, it is urgent to improve neutrino intensity

– Continuation of KEKB/Belle with upgrade

How to realize a string test in a timely manner ?How to realize a string test in a timely manner ?

Is European XFEL enough ? Yes and No. If DESY succeeded in achieving 31.5 MV/m,

why not purchase from the vendor ?

All the partners should benefit from contributing to the ILC. We need to convince our funding agency/government that contributi

on to the ILC is beneficial not only for its own sake but also other domestic projects such as ERL and/or SNS.

Advanced accelerator technology, SCRF technology in particular, has many spin-offs.

We will do our best to start ILC as soon as possible.however, our immediate goal for the next 5 years is not a start of full construction of the ILC, but construction of STF-3 and related R&D.

STF-like facility in China, India, or Korea will help to complete STF-3.

Some components may be supplied from abroad. ‘Plug-compatible’ concept makes it easier for overseas contribution.

Asian Office at KEKAsian Office at KEK

In order to facilitate collaboration with Asian partners, KEK would like to propose creating ‘Asian Offices’. Researcher(s) stationed at Asian Office work at KEK and liaise

with his/her home institute with respect to ILC R&D or other joint projects.

Asian Office is just a step forward to promote collaboration between Asian partners.
