The ILC International Development Team (IDT) was established by the International Committee for Future Accelerator (ICFA) in August 2020, to prepare the ILC Preparatory Laboratory (Pre-lab) that would complete the technical development and engineering preparation for the International Linear Collider project to be ready for construction.  During the same period, governmental authorities of interested nations are expected to forge an agreement on the sharing of the cost and responsibilities for the construction and operation of the ILC facility and on the organisational structure and governance of the ILC Laboratory.

After ten months of work, the IDT has achieved the first major milestone of completing the ILC Pre-lab proposal, which outlines the organisational framework, an implementation model and work plan of the Pre-lab. Three working groups were the key players and an impressive number of people have been contributing to this effort. Working Group 1 worked on the mandate, governance model, organisational structure and Pre-lab start-up procedure. Working Group 2 identified necessary technical development and engineering preparation work for the ILC accelerator and site construction. Working Group 3 discussed a strategy for developing the compelling ILC physics programme. Then the Executive Board took the responsibility of compiling the document. It was very encouraging to see the growing number of participants in those activities.

The IDT activity now enters the next phase of implementing the steps for establishing the Pre-lab along the lines described in the proposal. The plan for the accelerator technical development and engineering preparation work needs to be further elaborated and people and laboratories with interest and expertise in the work must be identified. The physics community needs encouragement and support for further exploring the physics potential of the ILC and converging towards concrete designs of experiments. Discussion on the Pre-lab start-up process must be initiated among the world key laboratories.

An equally crucial factor now is to understand what kind of process is needed to achieve the establishment of the Pre-lab. Unlike the ILC itself, the Pre-lab activities will be driven at the level of laboratories rather than having a direct involvement of governmental authorities. For the managements of interested laboratories to engage seriously in the discussion of responsibility sharing for the Pre-lab activities, however, a signal from the Japanese government indicating its interest in hosting the ILC and supporting the Pre-lab would be required. In parallel, we will make further effort to gain more support for the ILC worldwide.

We will continue to do our best for the swift realisation of the Pre-lab. Exciting times are head of us all.

  • Pingback from ILC準備研究所の設立提案書が公開される! - Accelerator Physics Group, Hiroshima University, “[…] ILCの建設に必要となる全ての技術と設計は、実際にILC研究所が設立される前に用意されていないといけません。それを行うのが準備研究所です。準備研究所の活動はILC実現の上でとても重要なステップです。今後、IDTがまとめた提案者は世界の素粒子物理学の研究者達の集まりであるICFAの承認のもとで、公開されました。お墨付きを得たこの提案書をもとに、準備研究所の設立を各国政府に呼び掛けていくことになります。準備研究所の設立に期待しましょう。ILC Newsline (英語サイト)http://newsline.linearcollider.org/2021/06/01/ilc-preparatory-laboratory-proposal-released/ […]”.
