2 One Year History of ILCSC Activities 2002 July 30 (Amsterdam) ILCSC was established by ICFA. Chair: Hirotaka Sugawara Mandate was decided by telephone conferences in spring The ILCSC will, 1.Engage in outreach, explain the intrinsic scientific and technological importance of the project to the scientific community at large, to industry, to government officials, and politicians and to the general public. 2. Based upon the extensive work already done in the three regions, engage in defining the scientific roadmap, the scope and primary parameters of machine and detector. It is particularly important that the initial energy, the initial operations scenario and the goals for upgradability be properly assessed.

3 3. Monitor the machine R&D activities and make recommendations on the coordination and sharing of R&D tasks as appropriate. Although the accelerator technology choice may well be determined by the host country, the ILCSC should help facilitate this choice to the largest degree possible. 4. Identify models of the organizational structure, based on the international partnerships, adequate for constructing the LC facility. In addition, the ILCSC should make recommendations regarding the role of the host country in the construction and operation of the facility. 5. Carry out such tasks as may be approved or directed by ICFA.

The ITRP should recommend a LC technology to the ILCSC. On the assumption that a Linear Collider commences before 2010 and given assessment by ITRC that both TESLA and JLC-X/NLC have rather mature conceptual designs, the choice should be between these two designs. If necessary, a solution incorporating C-band technology should be evaluated.

To reach its recommendation the Panel will hear from the design proponents addressing the above issue. ………. ………. The panel will need to know if there is a significant cost difference between the two designs being examined for completing the 500 GeV project and possibly any upgrade set forth in the ILC Parameters Document. ………. ………. The panel is urged to report its recommendation as soon as possible, with a firm deadline by the end of ……….. ……….. The Accelerator Sub-committee of the ILCSC is prepared to give an extensive tutorial on the LC. This would inform the Panel about LC issues and acquaint it with the experts from whom they can solicit advice. ………… ………… It is expected that the presentation sessions will be open to the scientific and funding agency communities.

9 We hope that there will be very serious and positive discussions in the ITRP. Any new results after the ILCTRC-II must be incorporated. (1) Costing of the project (1) Costing of the project The cost issues were not discussed at the ILCTRC-II (Greg Loew) Committee. The cost issues were not discussed at the ILCTRC-II (Greg Loew) Committee. The cost must be evaluated in the same basis. The cost must be evaluated in the same basis.

(3) Since the technology choice couples to many other issues, (3) Since the technology choice couples to many other issues, discussions on broad issues are expected in the panel. discussions on broad issues are expected in the panel. For example, the roles of the host and non-host regions/countries must be considered. For example, the roles of the host and non-host regions/countries must be considered. The accelerator subcommittee of ILCSC must supply all the available information to ITRP. available information to ITRP.

10 After the technology Choice We need a realistic international organization to proceed the international LC project. International share of the accelerator R&D without a hard commitment of the governments. The KEK Globalization Committee had considered a realistic way towards the construction of the international LC. The discussion at ILCSC shows essentially the same direction as the Globalization Committee. Only the difference is that the technology choice comes earlier than forming the pre- GLCC (Pre-Global Design Organization).

11 Organization (in the GLC Project Report ) Globalization Committee was formed at KEK in July 2001 Two extreme cases, (A) extension of existing laboratory and (B) creation of a new international laboratory based on treaties, and in between the two cases were discussed in the committee. (B) is the preferred way. Financial stability and security, sharing of cost, human resources and responsibilities, desired openness for the scientific opportunity. For Japan, hosting such laboratory would be very attractive and in accordance with its national plan for science and technology (S&T basic low, S&T basic plan).

12 Pre-GLCC A realistic way towards the GLCC (Global Linear Collider Center). Similar to the existing collaborations for high energy physics experiments. The foundation is based on MoU among laboratories and universities. Building up the co-working spirit by actual R&D works and designing works. Multi-international centers (like ITER) might be a realistic way to start with. Can be created now ! Now GLCC

17 We need to learn from ITER Advantages and disadvantages of the each stage of organization of ITER must be carefully investigated. As far as the structure of the international organization is concerned, we can learn from CERN and ITER. The international project must be stable, otherwise it will cause a fatal damage to the scientific community. We must learn from the case of the SSC project. It is very dangerous if the major decisions are given mainly by the politics. The decisions may well be connected to, for example, national defense policies.

18 The Global LC is a major challenge of the HEP society. In the past no one wants to listen to ICFA and many accelerators are duplicated in the same energy regions. However It was healthy, since the competition stimulates the scientific activities. SPEAR DORIS SPEAR DORIS PETRA PEP PETRA PEP SppS TEVATRON SppS TEVATRON SLC LEP SLC LEP SSC LHC SSC LHC KEKB PEPII etc KEKB PEPII etc Now LC must be a global project, since no single region can pay for the construction budget. To make this global system to work, we need some mechanism which avoid to have obvious losers in the global LC community. Although work-sharing and the regional balance are very important, the host must have heavy responsibilities Including the budget. The Global Linear Collider is not the last machine of the international HEP society.

20 ALCSC: Mandate The ALCSC will: - Promote Global Linear Collider Project as an international project based on the GLC Project Report, and make every effort to host the project. - Monitor and direct the international LC accelerator R&D and physics and detector studies in Asia. - Make an effort to form an international team (pre-GLCC) based on the bottom up procedure with possible international partners before forming the projec based on the governmental approvals. - Communicate with LCSC (LCSG) of other regions and as well as with ILCSC.
