ILC publishes its Technical Design Report

Next-generation particle accelerator is ready for construction

A five-volume report containing the blueprint for a future particle physics project, the International Linear Collider (ILC), was published today. In three consecutive ceremonies in Asia, Europe and the Americas, the authors of the Technical Design Report for the International Linear Collider, a next-generation particle collider to complement and advance beyond the physics of the Large Hadron Collider at CERN, officially handed the report over to the international oversight board for projects in particle physics, the International Committee for Future Accelerators ICFA. The Technical Design Report presents the latest, most technologically advanced and most thoroughly scrutinised design for the ILC.

“We thank the ILC team for this report and look forward to witnessing the next step of the project,” said ICFA Chair Pier Oddone. “The report is a testament to the global effort and cooperation that went into successfully designing a machine of this sophistication and scale.”

The centrepiece of the ILC, two superconducting linear accelerators for electrons and positrons, are based on the superconducting TESLA technology. For years, this technology was the subject of intensive research and further improvements at DESY, among others.

"Nevertheless the superconducting ILC technology is very ambitious, it is also particularly well-engineered. Currently, DESY il building the 2-kilometre long European XFEL accelerator, based on the same technology. The experience which we are gaining in cooperation with industry and other research centres will be extremely valuable for the construction of the International Linear Collider," said DESY´s Brian Foster, European Director of the Linear Collider Collaboration LCC.

"DESY particle physics and accelerator scientists made substantial contributions that helped the International Linear Collider reach the milestone Technical Design Report, virtually the maturity certificate of this project. We will continue to work also on detector technologies to harvest a maximum of scientific insight with this precision machine of particle physics," claimed DESY Research Director Joachim Mnich.

In a global event starting in Tokyo, Japan, continuing at CERN in Geneva, Switzerland, and ending at Fermilab, Chicago, in the United States, scientists and their guests are celebrating this achievement in symposia, public events, receptions and a series of handover ceremonies. At each regional part of this global event, one full set of the report is handed over and the three regions give each other a virtual handshake by videoconference when one celebration ends in one time zone and the next starts in another.

“The publication of the Technical Design Report represents a major accomplishment. A huge amount of work has gone into it. The TDR makes a convincing case: thanks to all the hard work, we now have a machine that we know we can build,” said Jonathan Bagger, chair of the International Linear Collider Steering Committee. “The ILC is good to go.”

“The Technical Design Report basically says that we are ready to go ahead,” said Barry Barish, Director of the ILC’s Global Design Effort. “The technology is there, the R&D milestones have been achieved, the physics case is clear, and we could start construction tomorrow. All we need is a clear political statement, and there are strong signs from Japan that it could bid to host the project.”

“The discovery of a Higgs boson at the LHC has made the case for the ILC even more compelling. The ILC can study its properties in detail and will thus be a great complementary machine to the already very successful LHC,” said Sakue Yamada, Research Director for the ILC.

“The Technical Design Report is an impressive piece of work that shows maturity, scrutiny and boldness. The International Linear Collider should be next on the agenda for global particle physics,” said Lyn Evans, Director of the Linear Collider Collaboration.

The Technical Design Report (TDR) marks the completion of many years of globally coordinated R&D and completes the mandate of the Global Design Effort. It contains all the elements needed to propose the ILC to collaborating governments, including a technical design and implementation plan, that are realistic and have been optimised for performance, cost and risk.

Highlights of the achievements include the successful construction and commissioning of superconducting radiofrequency test facilities for accelerators all over the world, great strides in the improvement of accelerating cavities production processes, and plans for mass production, as 16,000 superconducting cavities will be needed to drive the ILC’s particle beams. The details of the two state-of-the-art detectors that will record the collisions between electrons and positrons are also part of the report, as well as an extensive outline of the geological and civil engineering studies conducted for siting the ILC.

The design effort continues in the new Linear Collider Collaboration, which combines the two most mature future particle physics projects at the energy frontier, the International Linear Collider and the Compact Linear Collider (CLIC), in an official organisational partnership to coordinate and advance the global development work for the linear collider.
