Status of the project

Global Design Effort

An international team headed by Barry Barish leads the Global Design Effort for the proposed International Linear Collider ILC. Planning, designing and funding the ambitious electron-positron collider project will require global participation and global organisation. The GDE team sets the strategy and priorities for the work of hundreds of scientists and engineers at universities and laboratories around the world. Their goal: produce an ILC Technical Design Report by the end of 2012 which will be used to decide the future of the project, including where it would be located. In 2013, the International Linear Collider and the Compact Linear Collider (CLIC) merge to form one Linear Collider Collaboration, headed by former LHC project leader Lyn Evans.
The mission of the GDE is to produce a design for the ILC that includes a detailed concept for the particle accelerator, performance assessments, reliable international costing, an industrialisation plan, siting analysis and governance proposal. The organisation coordinates worldwide R&D efforts according to well-defined priorities to demonstrate and improve the performance of the ILC machine components, reduce the costs and attain the required reliability.

Global Design Effort activities:

The GDE supervised the production of a baseline design for the ILC, which was completed in late 2005. This baseline design has been used as the foundation for the more detailed Reference Design Report, published in 2007, which provides a technical description of the project and includes an initial value estimate. The RDR is a basis for identifying priorities for the next engineering phase of the ILC project and a worldwide R&D programme for further cost reduction and improved performance.

The current phase, the Technical Design Phase (TDP), will produce a technical design of the project in order to demonstrate its feasibility to all involved governments so the ILC can be approved and eventually built. The draft of the Technical Design Report (TDR) has been handed over to its internal oversight board ILC Steering Commitee (ILCSC) on December 15, 2012, and the final version of the TDR will be officially delivered to the International Committee for Future Accelerators (ICFA) in June 2013.

At the end of the Technical Design Phase the TDR will complete and document an integrated engineering design of the accelerator. This design should satisfy the energy, luminosity, and availability outlined in the RDR, and should include a more complete and accurate value estimate. It will also highlight thoughts on possible governance models for the International Linear Collider as an international research endeavour. It will demonstrate that the project can be built within the specified budget and that it can deliver the required performance.

Physics and detectors

The ILC Research Director, Sakue Yamada was named in 2007 to provide guidance for the global detector R&D activities and coordination of the procedures for developing engineering designs for two complementary detectors, published as a volume on physics and detectors in the TDR. The World Wide Study representatives serve as regional contacts to facilitate this task.

The detectors:
Two detector concepts groups are working on complementary detectors called the International Large Detector (ILD) and the Silicon Detector (SiD). Both are made of international teams of detector experts. In 2009 the ILC detector activity entered a new stage with the submission of the three Letters of Intent and the start of evaluation of these concepts by the International Detector Advisory Group (IDAG). The validated detectors, ILD and SiD, are submitting detailed baseline designs by the end of the Technical Design Phase.
