ICFA and the Linear Collider ICFA has been helping to guide international cooperation on and try to realize the Linear Collider more than 10 years. Major steps: 1995: First LC TRC Report, under Greg Loew as Chair 1999: ICFA Statement on Linear Collider 2002: ICFA commissioned the second LC TRC Report, under Greg Loew as Chair 2002: ICFA has established the ILC Steering Committee (ILCSC) with Maury Tigner as Chair

ILCSC Charter(2002) Engage in outreach, explaining 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 Based upon the extensive work already done in the three regions, engage in defining the scientific roadmap, the scope and primary parameters for machine and detector. It is particularly important that the initial energy, the initial operations scenario and the goals for upgradeability be properly assessed. -> Set up GDE

ILCSC Charter (cont) 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. -> Setup ITRP and GDE, and then MAC Identify models of the organizational structure, based on 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. -> Collaboration with FALC ->Next Step

ILCSC Charter (cont) Carry out such other tasks as may be approved or directed by ICFA -> The role of ILCSC will be discussed at the next ICFA meeting (February 10, 2006 at CERN) “ The mandate of the ILCSC shall be reviewed by ICFA in three years to determine if the purpose is being properly served and remains appropriate or if the activity should be terminated.” ICFA meeting held on February 9 and 10, 2006, at CERN has decided that ILCSC shall continue its role.

Summary of ILCSC meetings in Snowmass （ 05/08/23) and Daegu (05/09/27) ILCSC reconfirms that it is the only oversight body of GDE. the regional committees provide input to ILCSC and have no oversight role. ILCSC has finalized the Annex to GDE MoU. The regional committees will produce lists of possible signatories from their regions. ILCSC will review the lists, and form guidelines for what types of institutions can sign. ILCSC is going to set up Machine Advisory Committee by the end of MAC will report to ILCSC and give advice to GDE. MAC members should be selected by their expertise. It will have the first meeting early 2006

ILC DGE ILC-MOU : Signed on May 10, 2005

MAC Mandate 1. As one of the ILCSC oversight activities of GDE, MAC (Machine Advisory Committee) will be formed. 2. MAC will review the GDE activities with respect to accelerators and report to ILCSC, and, at the same time, give advice to GDE director. 3. MAC will review BCD as soon as the document is released, and then 、 review the activities of GDE at appropriate time until RDR is finalized. 4. We assume that MAC will meet twice a year during this period. Comment: Number of MAC members is 10-12, and members shall be selected mostly on the basis of their expertise and not on the basis of regional balance.

Summary of ILCSC meetings in Snowmass （ 05/08/23) and Daegu (05/09/27)(cont) ILCSC will have a close consultative relationship with the FALC (Funding Agencies for Linear Collider) groups. ILCSC proposes that ICFA Chair and ILCSC Chair be invited to FALC meetings, and ILCSC Chair to FALC RG meetings. GDE will keep the FALC group well informed. Next ILCSC meeting will be held at CERN on Feb 9, 2006 and the one after the next will be held in Zeuten in early May.

ILCSC and Its Next Step ILCSC will continue to oversee GDE until GDE gets organized under a federation of worldwide government agencies and something like interim council. At that time ICFA and ILCSC will step aside. A natural time for ICFA/ILCSC to hand off the GDE oversight to such a body would be at the transition from Reference Design (RDR) to Technical Design (TDR). The delay should be minimized; however, before the establishment of the federation of worldwide government agencies ICFA/ILCSC should not step aside. Coming years are crucial years for ILC, since to realize above-mentioned transition needs a lot of work, cooperation, and wisdom.

Discussion in FALC meeting on November 4, 2005 FLAC insists that it will oversee the GDE for funding. It complains about the dashed lines between FLAC and GDE. FALC plans to set up a sub-committee consists of a few members in January to discuss how to evolve FALC toward the international management of ILC. FLAC wishes send its RG Chair to ILCSC meetings and its Chair to ICFA. FALC has agreed to invite ILCSC Chair to FALC and FLAC RG meetings and ICFA Chair to FLAC meetings. FALC proposes that the common fund to support GDE activities be divided into 1/3, 1/3, and 1/3 to each reagion.

Summary of ILCSC meeting on February 9, 2006, at CERN ILCSC and FALC (FALC-RG meeting was held on February 8, 2006, at CERN) Machine Advisory Committee (MAC) Preparatory Committee of ILCSC Possible increase of Signers of MoU WWS Next ILCSC meetings Discussion at ICFA meeting (February 10, 2006)

FALC and ILCSC - ILCSC invites FALC-RG Chair (Richard Wade) to the meeting. - SK (he attended the last FALC meeting as an observer) reported on FALC meeting in November and Wade reported on the FALC-RG meeting held yesterday.(in the FALC-RG meeting one comment was made that FALC and FALC-RG should be responsible only to the common fund, and no strong objections to this comment) - FALC has decided that the common fund shall be supported 1/3 per region. Wade reported that FALC-RG discussed the MoU of cost sharing. - ILCSC has agreed that it needs good interaction with FALC and for this purpose ILCSC will invite FALC-RG Chair to every meeting. - ILCSC also discussed the issue of evolution of FALC raised in the last FALC meeting. ILCSC has concluded that FALC shall be evolved from inside and the interaction with FALC shall be done by attendance of ILCSC Chair to FALC and FALC RG meetings

Machine Advisory Committee - In the last ILCSC meeting ILCSC has decided to setup MAC (machine advisory committee) which monitors the GDE activities with respect to machine design and R&D. - ILCSC has formed a nomination committee consisting of four members (Wagner, Dorfan, Namkung, and SK). Although it took longer time than planned the nomination committee has reached a consensus about Chair of MAC (Ferdi Willeke of DESY) and proposed this nomination to ILCSC. ILCSC has endorsed this proposal. - The nomination committee plus Willeke will work on selection of the members of the MAC and the names should be fixed as soon as possible. - It has been also agreed upon that Chair of ILCSC will participate in MAC as ex-officio and that MAC will have secretary. - MAC members who belong to major laboratories with respect to ILC activities shall be supported by their institutes for their participation in MAC meetings. In other cases the common fund shall be used. The first MAC meeting shall be held before early April.

Preparatory Committee of ILCSC - It was proposed in the last ILCSC meeting that ILCSC set up an Executive committee to make the ILCSC respond much timely and quickly. - In this meeting ILCSC has agreed that instead of the Executive committee ILCSC will set up a preparatory committee (good name shall be found soon) which prepares agenda and make the decision making of ILCSC much easier. - Roy Rubinstein, Maury Tigner, and SK will work on suggested mandate for ILCSC approval.

Possible increase of Signers of MoU In order to enlarge GDE activities each region has thought about possible participating institutes that become signers of the MoU. Names of a few institutes are suggested.

WWS - Francois Richard made a report on WWS activities. - He emphasized that it was not good strategically if too low budget would be assigned to detector R&D, since good detectors could effectively increase the luminosity. ILCSC recognizes the situation. - Richard also reported that WWS had set up two panels, R&D panel and Machine-Detector Interface panel, the former outside of GDE, and the latter interfacing WWS to GDE. - He also reported that three WWS members had joined in GDE as representatives of WWS.

Next ILCSC meetings The next ILCSC meeting will be held on May 8 in Zeuten and one after the next will be held during the ICHEP conference in Moscow.

ACFA Asian Committee for Future Accelerators Officially established in the First Plenary ACFA meeting held in 1996 at POSTECH, Korea

Purpose The primary purpose of ACFA shall be to strengthen regional collaboration in accelerator-based sciences. In particular, ACFA seeks cooperative ways: to facilitate efficient utilization of existing human and material resources, to bring up accelerator scientists of the next generation, and to encourage future accelerator projects in Asia and to make recommendations for them to governments.

ACFA and ILC ACFA strives to get the LC in Asia Three ACFA statements were issued in 1997, 2001, and 2004 Should approach all Asian governments & convince them to participate actively in LC Identify the R&D capabilities and industrial strength to optimize the cost for LC Training of Asian manpower through workshops, schools, conferences & exchange of scientists There will be vast opportunities for each country to contribute to the success of LC. ALCSC(ACFA Linear Collider Steering Committee, Chair W. Namkung) has been formed in 2002

The Third ACFA Statement on International Linear Collider issued on Nov. 3, 2004 at the 9th Plenary ACFA Kolkata, India

Essence of the ACFA Statement ACFA welcomes the truly international nature of the decision on technology for the ILC. This sets the stage for international collaboration in the design efforts for the ILC. 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. With ILC entering this important phase, ACFA urges Governments of Asian countries to support participation of their scientists in GDI.

Asian Prospects and Issues Asia has a good potentiality to be the host of ILC with its largest accumulation of talented people and largest GDP in 2020 among three regions. Though at present, differences among countries are very large, and large effort is necessary to overcome this difference. We should make interaction among researchers in the Asian world much stronger. Also it is important to invite researchers from Asian countries that have not actively participated in the ILC activities. With ILC entering this important phase, ACFA urges Governments of Asian countries to support participation of their scientists in GDE.

A few Words from ILCSC Chair I highly appreciate the great efforts of Maury as Chair of ILCSC and the ILCSC itself, its sub-committees, and ICFA, to establish GDE as a single team to design ILC on the basis of the world-wide unified approach. We should not slow down the present momentum towards the realization of ILC. The most important issue for ILCSC is to create a good international management scheme for the truly global ILC, where any high-energy physicists from any countries can participate by collaborating with FLAC and other international organizations. In addition to ILC-Asia activities we need to strengthen ALCSC activities.
