On 12 June 2013, a five-volume report containing the blueprint for a future particle physics project, the International Linear Collider (ILC), was published. The

Technical Design Report presents the latest, most technologically advanced and most thoroughly scrutinised design for the ILC.

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.

Prof. WANG Yifang, Director of the Institute of High Energy Physics joined the ceremony in Tokyo via network video and delivered a speech. He emphasized: “In August, 2004, ICFA announced the adopted technology for ILC at IHEP in Beijing. Today, on behalf of the Chinese High Energy Physics Community, I am honored to share with you our strong emotion and full support for ILC. We will certainly be part of it and make our contributions.”

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.

The Chinese scientists have been involved in the ILC R&D efforts, including overall design of the accelerator, studies on particle dynamics, damping ring design, 1.3 GHz superconducting cavity and accelerating components, advanced beam diagnosis and detector, etc.
