How a new HEP project is undertaken in Japan

Japanese HEP community discusses and recommends a few prioritized projects to KEK.

KEK and MEXT (funding agency) discuss budgetary constraints. KEK submits a formal proposal to MEXT by picking up a realistic

one among the projects recommended by the community MEXT asks a standing committee to review and approve it

Sub-committee for Basic Science under Committee for Science and Technology, MEXT

Approval from other committees is necessary, if the project is conducted jointly with other institute J-PARC.

Final approval by CSTP, Cabinet Office (~ OSTP in the US)

Mission Policy to promote ST in a general and organized way Policy on budget and personnel for ST To review big projects

According to the 2nd ST 5-year basic plan (2001 – 2005) made by CSTP the government is expected to spend 20.7 Trillion \ (~ 200 B$), though 24 T\ was planned. Fraction of basic researches ~ 40%

CSTP’s 3rd 5-year basic plan (2006 – 2010) is under discussion and will be ready in February 2006.

Large-scale ST proposals are reviewed, considering whether they are consistent with the ST basic plan. ILC would be the case like ITER.

2004 Statement from JHEPC (Japanese HEP Committee)

Upon the ITRP's technology choice, the JHEPC, after leading the discussion in Japanese community as to how Japan should proceed to the new stage of the ILC researches after the decision, confirms as the consensus of the high energy physics community in Japan that scientists and engineers in Japan should cooperate to realize the ILC by actively participating in the activities of the Global Design Initiative (GDI) of the ILC.

The JHEPC therefore urges that more scientists and engineers work on their own initiative in closer cooperation with industry for the ILC and play the leading role in the GDI. The JHEPC also supports KEK's proposal to host the Central Team of the GDI.

1997, 2001, and 2004 statements from ACFA (Asian committee for future accelerators)

Excerpt from 2004 statement: ACFA reaffirms that the ILC, the next major high-energy physics

project, should be realized by world-wide efforts. In such International collaboration ACFA and scientists in ACFA countries should play crucial and leading roles.

ACFA reconfirms the importance of hosting ILC in Asia, which will make high energy physics and accelerator science truly global.

ACFA urges Japanese Government to fully support the efforts of KEK and Japanese scientists to host the ILC in Japan.

ACFA urges KEK to establish the Asian Regional Center for R&D in GDI and encourages other Asian countries to actively participate in GDI.

With ILC entering this important phase, ACFA urges Governments of Asian countries to support participation of their scientists in GDI.

2004 ICFA statement (excerpt)

ICFA welcomes the January 2004 OECD Ministerial Statement on International Cooperation on Large Accelerator-based Projects in High-Energy Physics, which “acknowledged the importance of ensuring access to large-scale research infrastructure and the importance of the long-term vitality of high-energy physics. They noted the worldwide consensus of the scientific community, which has chosen an electron-positron linear collider as the next accelerator-based facility to complement and expand on the discoveries that are likely to emerge from the Large Hadron Collider currently being built at CERN. They agreed that the planning and implementation of such a large, multi-year project should be carried out on a global basis, and should involve consultations among not just scientists, but also representatives of science funding agencies from interested countries. Accordingly, Ministers endorsed the statement prepared by the OECD Global Science Forum Consultative Group on High-Energy Physics (see Appendix).”

ICFA reaffirms its conviction that the highest priority for a new machine for particle physics is a linear electron-positron collider with an initial energy of 500 GeV, extendible up to about 1 TeV, with a significant period of concurrent running with the LHC.

21

EPP2010 050516

Following the statements from JHEPC, ACFA and ICFA, KEK will actively participate in GDE design work and R&D to realize ILC, and strengthen joint work among Asian institutes.

KEK signed for GDE-MOU. Asian MOU for R&D efforts toward the Realization of the ILC is under discussion.
