Directorate and committees

The International Linear Collider project is now part of the Linear Collider Collaboration, LCC. Until the completion of its Technical Design Report it was managed by a small team called the Global Design Effort Executive Committee, which consisted of ILC Director Barry Barish, three Directors for each of the regions of the ILC (Americas, Asia and Europe), three project managers, also one from each region, and a few specialists. The Executive Committee and Director reported to the International Linear Collider Steering Committee which was created by the International Committee for Future Accelerators ICFA. Under the new LCC, the ILC effort is managed by Mike Harrison, BNL, leading the working groups that plan and manage the development of the accelerator, or 'machine', itself. The development of the future detectors, formerly overseen by the Research Directorate, is now also part of the LCC and managed by Hitoshi Yamamoto.
 

Some ILC-related committees, in alphabetical order

ACFA
Asian Committee for Future Accelerators

ACFA's primary mission is to strengthen regional collaboration in accelerator-based science. It seeks cooperative ways to facilitate the utilisation of existing human and material resources, to bring up scientists of the next generation, and to encourage future projects in Asia and to make recommendations for them to local governments. ACFA carries out its business with any active region in Asia that is willing to contribute toward the advancement of accelerator-based science. A strong focus of ACFA is the effort towards a linear collider and Asia's role in this effort and the committee lends support to the technology decision, as well as to the concept of developing a world-wide effort toward realising the ILC.

ALCPG
American Linear Collider Physics Group

ALCPG has been created to establish and manage a process that leads to a forefront experimental programme at a high-energy electron-positron linear collider. To be successful, this process must demonstrate that such a physics programme can, with a high level of confidence, be carried out within a reasonable time frame and within a reasonable budget. Given the strong international interest in this physics, the ALCPG's role should be understood as the North American part of a larger global effort. The ALCPG should maintain strong ties to other groups with similar goals around the world.

EC
Global Design Effort Executive Committee
The Executive Committee coordinates the activities of the Global Design Effort. Its members meet once a week per teleconference and face-to-face every few months. It is comprised of ILC Director Barry Barish, the three regional directors – Michael Harrison (Americas), Kaoru Yokoya (Asia), and Brian Foster (Europe), the three project managers – Marc Ross (Fermilab), Akira Yamamoto (KEK), and Nick Walker (DESY) – and experts who work on integration and costing issues. More experts may be added to the committee in the coming years. This simple Global Design Effort management structure helps to guide the global R&D and design effort. The EC centralises much of the policy decision making and provides guidance for the overall programme.

ECFA
European Committee for Future Accelerators

ECFA promotes international collaboration for the creation of European high-energy facilities for a high-quality research programme for the community of physicists in the participating countries. ECFA fosters successful collaboration between international and national laboratories and university institutes in this research, and ensures that a close relationship exist between research and education in high-energy physics and other related fields. It is responsible for the long-term planning of European high-energy facilities: accelerators, large-scale facilities and equipment. It members are representatives from all CERN member and observer states and European lab directors.

FALC
Funding Agencies for Large Collaborations

Funding Agencies for Large Collaborations (FALC) is a group of representatives from funding agencies and governments around the world. Its purpose is to help develop international funding mechanisms for large physics facilities like the International Linear Collider. FALC meets on a regular basis with members of the Global Design Effort to establish a dialogue between the funding agencies, governments and the ILC scientific community. The FALC Resources Group manages the so-called Common Fund that supports central ILC functions.

ILC Project Advisory Committee (PAC)
The International Linear Collider Steering Committee (ILCSC) is responsible for the oversight of the Global Design Effort (GDE) activities and of the ILC experimental programme, and the PAC assists ILCSC in this function and report to the ILCSC. PAC reviews the GDE accelerator activities and, in addition, the ILC detector activities. In its review activity, PAC examines the overall consistency and realism of the project, in relation to physics, technical design, cost, and schedule. PAC shall comprise about nine members, appointed by the ILCSC for terms of two or three years, and will meet a few times per year until the completion of the Technical Design Phases I and II. The PAC Chair will be appointed by the ILCSC, normally for a two-year term.

ICFA
International Committee for Future Accelerators

Since 1976, the International Committee for Future Accelerators (ICFA) has facilitated international collaboration in the construction and use of accelerators for high-energy physics. The 16 ICFA members include the directors of the world's largest accelerator laboratories as well as representatives of the worldwide particle physics community. ICFA members usually meet twice a year to discuss plans for new accelerator facilities and topics such as instrumentation, accelerator technology, and research programmes. In 2002, ICFA created the International Linear Collider Steering Committee to define the scientific roadmap for an electron-positron linear collider as an international project. In March 2005, ICFA appointed Barry Barish as Director of the Global Design Effort.

IDAG
International Detector Advisory Group

A group of experienced experimentalists, active phenomenology theorists and ILC accelerator experts who validate the Letters of Intent for the planned ILC detectors and general detector R&D matters. They advise the Research Director.

ILCSC
International Linear Collider Steering Committee

The primary role of the International Linear Collider Steering Committee is to promote the construction of the International Linear Collider through world-wide collaboration. Its 15 members define the scope and primary parameters for the machine and its detectors, monitor the R&D activities, and make recommendations on the coordination and sharing of R&D tasks. The ILCSC was established by ICFA in order to facilitate global support for the realisation of the International Linear Collider (ILC) as a global collaborative effort. The ILCSC established the Global Design Effort (GDE) central team to coordinate and direct the effort of the teams in Asia, Europe and the Americas that comprise the GDE.

The Research Directorate Executive Board
The research directorate is responsible for the development of the experimental programme of the ILC for physics and detectors. Its executive board is comprised of ILC Research Director Sakue Yamada and three regional contacts – Jim Brau (Americas), Hitoshi Yamamoto (Asia) and François Richard (Europe).
