  1. ILC Status in Japan Hitoshi Yamamoto Tohoku University November 29, 2013 Orsay, Paris

  2. HEP Community

  3. KEK roadmaps • 2007 • ILC at the top of the pyramid • 2013 • KEK will play a central role in creating an international preparatory group and will lead the effort on advanced R&D, the engineering design of the apparatus and facility, and the organizational design toward groundbreaking for the linear collider project to be hosted in Japan, within the framework of a global collaboration.

  4. JAHEP (Japan Association of High Energy Physicists) • A report on large projects (March 2012) • On ILC: Should a new particle such as a Higgs boson with a mass below approximately 1~TeV be confirmed at LHC, Japan should take the leadership role in an early realization of an e+e- linear collider. In particular, if the particle is light, experiments at low collision energy should be started at the earliest possible time. (Now, Higgs particle has been found and it is ‘light’) • A proposal for staging of ILC (October 2012) • Staging • A Higgs factory with a CM energy of ~250 GeV to start • Upgraded in stages to ~500 GeV (TDR baseline) • Technical expandability to ~1 TeV to be secured • Guideline for cost sharing • The host country to cover 50% of the expenses (construction) of the overall project of the 500 GeV machine. The actual contributions left to negotiations among the governments.

  5. ILC Candidate Site in Japan Kitakami • Kyushu • Sefuri mountains • Tohoku • Kitakami mountains ‘ILC site evaluation committee’ (JAHEP) Co-chairs: Kawagoe, Yamamoto evaluated them based on • Geology and other technical aspects • Infrastructure and economic ripple effects Selected the Tohoku Site Sefuri

  6. Tohoku Site (Katakami Mountains) • Flexibility in positioning the 50 km route • Shorter access tunnels • Natural Drainage • etc…

  8. International Supports • Europe : ‘European Strategy’ (March 22, 2013) • There is a strong scientific case for an electron-positron collider, complementary to the LHC, that can study the properties of the Higgs boson and other particles with unprecedented precision and whose energy can be upgraded … The initiative from the Japanese particle physics community to host the ILC in Japan is most welcome, and European groups are eager to participate. Europe looks forward to a proposal from Japan to discuss a possible participation. • US : HEPAP facilities subpanel report (March 22, 2013) • The initiative from the Japanese particle physics community to host the ILC in Japan is very welcome, and the U.S. particle physics community looks forward to a proposal from Japan to discuss possible participation. • For the final US strategy, wait for the HEPAP subpanel (P5) report (March-May, 2014)

  9. National Politics

  10. LDP (The Ruling Party)election platform ‘ILC’ appears twice explicitly 32 Rebuilding true command tower functions that strongly advance science and technology policies • …We will actively promote the critical fields of energy creation, energy conservation, energy storage, etc. as knowledge-concentrated national strategies - for example, our country should be able to play a leading role in creation of international centers for scientific innovations such as the ILC (the international linear collider) project which is a grand project in the field of particle physics. 92Creation of globally top-class centers for research and development • …We will significantly strengthen supports for universities and public research facilities that perform studies at levels above the intentional standards, such as significant expansion of WPIs and playing a leading role in creation of international centers for scientific innovations such as the ILC (the international linear collider construction) project which is a grand project in the field of particle physics.

  11. Policy Speech by PM Abe(Japanese version of ‘State of the Union’)Feb 28, 2013 • ‘Japan is driving global innovation in cutting-edge areas, including among others the world's first production test of marine methane hydrate, a globally unparalleled rocket launch success rate, and our attempts to develop the most advanced accelerator technology in the world.’ PM Abe at the 83rd session of Diet

  12. Press conference by the MEXT minister ShimomuraJan 18, 2013 ‘(On ILC) We would like to consider the plan for the near future, while as the government actively negotiating with relevant countries in the first half of this year … we are now studying the legal framework.’ Government has already started to contact (unofficially) relevant countries. So far, not very positive responses.

  13. Science Council of Japan Requested by the MEXT to review the ILC situation. Report submitted : Sep 30, 2013. • …we fully acknowledge the necessity and academic value of an electron-positron collider that is complementary to the LHC. • …the Science Council of Japan proposes that the Japanese government appropriate necessary fund to study various issues toward deciding the implementation of the ILC project, and intensively conduct examinations and studies for 2 to 3 years by a group including experts outside of the relevant field and related government offices. • In parallel with the above study and examination, negotiations should be conducted with research laboratories and funding authorities of relevant countries and regions to clarify the issues such as the international cost sharing. (Unofficial translation by HY)

  14. Science Council of Japan Report • It also stated ‘It is too early for the full implementation of the ILC’. (unofficial translation by HY) • This is a matter of course since the ILC is an international project that requires commitments of participating countries and regions before such can be decided. • MEXT has requested ~$0.5M for the investigatory study on the ILC, and a committee is being formed responding to the report. • A major milestone would be reached when it is approved by the financial department. • The ILC task force had been formed in Feb 2013, headed by the MEXT vice minister.

  15. Diet • ‘Federation of Diet Members for Promotion of the ILC’ • Established in 2008 • Expanded to a multi-partizan group • Re-invigorated after the Higgs discovery: now ~160 diet members (out of 700 total) • New chair: Mr. Kawamura (former MEXT minister)

  16. Mr. Kawamura’s Talk at LCWS13 • Text (in English) • Can be downloaded from the LCWS13 home page • Highlights • We are aware that people are usually worried that an increase of academic budget in one field may mean a decrease in other fields. … We shall arrange a dedicated budget to accommodate its much wider implications. It is the responsibility of the government to carry this out. • The Department of Education has requested the Department of Finance to provide an ILC investigation fund of 50 million yen in next year's budget. … once it has been approved, we members of the house will have achieved one of the most important milestones of recent years.

  17. Private Sector

  18. Science-Industry Alliance • ‘Advanced Accelerator Association for promoting science and technology (AAA)’ • Established in 2008 • Headed by a former CEO of Mitsubishi Heavy Industries: Mr. Nishioka • Hitachi, Toshiba, Mitsubishi, etc. • ~90 industries + ~30 universities • Intensive activities: • Lecture series, symposiums • Civil engineering study • Studies on large projects • Science-industry cooperation • …

  19. Support by Industries: A report by the Association of Corporate Executives (経済同友会: one of the two such groups in Japan） ‘… The Japanese government should announce the intention to site the ILC in Japan, and propose to related countries to begin discussions toward its realization. ‘ (Apr 2013) Issued a supporting comment (Aug 2013) Japan Chamber of Commerce&Industries Issued a similar comment (Aug 2013)

  20. Japan Policy Council • A private organization (an influential thinktank) • Led by Hiroya Masuda • Professor of University of Tokyo • Former minister of internal affairs and communications • Former governor of Iwate prefecture • Issued a report: • Build a role model for the creation of a global city by reforming a local city through founding an international organization for the International Linear Collider (ILC).

  21. MediaCoverage of the ILC • Many TV and newspaper coverages • ‘Close-up Today’ (クロースアップ現代）Feb 2013 NHK’s flag-ship news program (30 min) ‘Go beyond Higgs – Japan’s Large Accelerator Project’ Anchor: Hiroko Kuniya

  22. ILC Timeline Proposed by LCC • 2013 - 2016 • Negotiations among governments • Accelerator detailed design, R&Ds for cost-effective production, site study, CFS designs etc. • Prepare for the international lab. • 2016 – 2018 • ‘Green-sign’ for the ILC construction to be given (in early 2016 ) • International agreement reached to go ahead with the ILC • Formation of the ILC lab. • Preparation for biddings etc. • 2018 • Construction start (9 yrs) • 2027 • Construction (500 GeV) complete, (and commissioning start) (250 GeV is slightly shorter)

  23. Summary • The discovery of Higgs has greatly invigorated ILC activities in Japan at many levels. • Japanese government is moving seriously toward realizing the ILC in Japan as a truly international project. • International agreement among relevant countries is essential for Japanese government to decide to host the ILC. • In order for relevant governments to act positively on the ILC, it is critical that they see that researchers in their own country wants the ILC.

Q&As at the DietMar 4, 2013 • Q : Mr. Ohata’s Question on the ‘Strategy for Growth ‘Establishing science&technology and intellectual property rights has greatly contributed to the progress of Japan in the past. What is your thought on the basic science&technology including the linear collider?’ • PM Abe’s answer on the ILC ‘We will pull along the innovations through accelerator technologies that are at the global state-of-the-art. The ILC is part of it and it is a project that inspires great dreams. On the other hand, it requires a large amount of budget.’ ‘As the government, we will proceed checking the progress of the international design activities at researchers’ level .’ (There have been many answers in the Diet by Ministers in the past)
