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 RD

23
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

24
  • ILC is an exceptionally large project
  • DGs 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

25
  • 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 environmental 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
