Towards the realisation of the International Linear Collider

22 April 2015, Tokyo

Press Release

At the ILC Tokyo Symposium, held on 22 April 2015 at the Ito International Hall, Tokyo, Japan, the Linear Collider Collaboration (LCC) and the more than 300 participants from around the world at the Asian Linear Collider Workshop (ALCW) 2015 decided to issue a statement confirming their conviction of the scientific justification for a prompt realisation of the International Linear Collider (ILC).

  1. The ILC’s role in particle physics is to explore with exquisite detail the fundamental forces and constituents of matter by recreating the conditions just after the beginning of the Universe,. This research is unique and indispensable for a deep understanding of how our Universe began, how it evolved, and how it works today. We are eager to build and work at the facility.
  2. The technical feasibility of the ILC has been demonstrated in the Technical Design Report, The ILC is ready to be built following the completion of an engineering-design phase. The project is now in a phase where governmental involvement should lead to a decision to realise the project. In this context we express our appreciation of the ongoing project assessment being undertaken by the Japanese government. 
  3. The ILC is one of the largest scientific projects ever proposed, on a similar scale to the Large Hadron Collider project. Its realisation as an international project requires the establishment of an international framework for sharing the cost and expertise among countries. We therefore intend to facilitate discussions between governments and funding authorities to achieve this goal as soon as possible.

Background information: 
The International Linear Collider is a proposed particle accelerator whose mission is to carry out research about the fundamental particles and forces that govern how the Universe works. It would complement the Large Hadron Collider at CERN, where the Higgs boson was discovered in 2012, and shed more light on the discoveries scientists have made and are likely to make there in the coming years. The ILC will be one of the world’s largest and most sophisticated scientific endeavours. The realisation of the ILC will require truly global participation.
The Linear Collider Collaboration consists of scientists and engineers working on the Compact Linear Collider Study (CLIC) and the International Linear Collider (ILC). It is headed by former LHC Project Director Lyn Evans and coordinates the world-wide research and development for accelerators and detectors.
