LC Project Office

Leading role at Asian regional team Signed on GDE MOU

Close collaboration with US and Europe under the Japan-US program and TESLA Technology Collaboration

Asian collaboration Core groups: IHEP (China); CHEP, PAL (Korea), TIFR, CAT

(India), KEK (Japan) Signed on Asian MOU

Active R&D ATF / ATF2: Damping ring, BPM, Beam-delivery STF: SRF technology, High-gradient cavities


Summary of the current status

Transition from 12 GeV PS to J-PARC: highest priority Researches with neutrons, muons and neutrinos will lead

the world

Mature BELLE and KEKB Very old light sources but very active ILC R&D


Future of KEK

Two simultaneous considerations New light source

ERL

New e+ e- collider ILC Super-KEKB

Long term: Upgrade of J-PARC to 4 MW


ILC is an exceptionally large project DG’s private committee to seek the possibility of hosting

the ILC in Japan

KEK trustees started discussion on the future vision of KEK Interim report by the end of the year Report by the end of 2006


The 3rd five year plan (2006 – 2010) for science and technology in Japan under discussion

During 2nd 5 year plan (2001 – 2005) the government spent 18.76 trillion-yen (170B$)

Promotion of basic science Dominated by biology, nano-materials, informatics and envir

onmental science

Strategic science and technologies IT, life science, materials science, environment

Big sciences prioritized under strict review International cooperation, especially with Asia

Necessity of hosting an international science and technology center in Asia recognized among politicians
