Editing International Linear Collider (section)

==Proposed sites==
Originally, three sites for the International Linear Collider were leading contenders at established High Energy Physics centers in Europe.<ref>{{cite web

This site was considered favorable for a number of practical reasons but due to the [[LHC]] the site was disfavored. At [[DESY]] in Hamburg the tunnel is close to the surface in water saturated soil. Germany leads Europe for scientific funding and was therefore considered reliable in terms of funding. At [[JINR]] in [[Dubna]] the tunnel is close to the surface in non-permeable soil. [[Dubna]] has a pre-accelerator complex which could have been easily adapted for the needs for the ILC. But all three were more or less well suited for housing a Linear Collider and one had ample choice for a site selection process in Europe.{{Cn|date=October 2024}}

Outside Europe a number of countries expressed interest. Japan receives a large amount of funding for neutrino activities, such as the [[T2K experiment]], a factor not in its favor, although 20 huge caverns with access tunnels have already been constructed in Japan for hydroelectric power plants (e.g. the [[Kannagawa Hydropower Plant]]). Following the closure of the [[Tevatron]] some groups within the USA had expressed interest, with [[Fermilab]] being a favored site because of the facilities and experts already present. Much of the speculated interest from other countries was hearsay from within the scientific community, and very few facts were published officially. The information presented above is a summary of that contained in the International Workshop on Linear Colliders 2010 (ECFA-CLIC-ILC Joint Meeting) at CERN.<ref>{{cite web

This decision was informed partly by the [[Science Council of Japan]]. The Japanese government sought monetary support from other countries to help fund this project.<ref>{{Cite web|url=https://www.scientificamerican.com/article/japan-delays-decision-for-hosting-next-big-particle-collider/|title=Japan Delays Decision for Hosting Next Big Particle Collider|last=Garisto|first=Daniel|website=Scientific American|language=en|access-date=2019-03-14}}</ref>

In 2022, the Japanese plan for the ILC was "shelved" by a panel for Japan’s Ministry of Education, Culture, Sports, Science and Technology (MEXT) <ref name=iop2022>{{cite news |author=Michael Banks  |title=Panel calls on physicists to 'shelve' notion of Japan hosting the International Linear Collider|url=https://physicsworld.com/a/panel-calls-on-physicists-to-shelve-notion-of-japan-hosting-the-international-linear-collider/|publisher=Physics World, IOP Publishing |date=March 1, 2022 }}</ref> Several reasons were given, including potentially insufficient international support and the CERN proposal for the [[Future Circular Collider]], which has overlapping physics goals with the ILC.

In March 2024, the "Federation of Diet Members for the ILC" met to receive "Reports on the ILC project's progress and initiatives by relevant organizations".<ref name=":1">{{Cite web |last=Takahashi |first=Rika |title=Federation of Diet Members resolves to promote the ILC in Japan {{!}} ILC Newsline |url=https://newsline.linearcollider.org/2024/07/08/federation-of-diet-members-resolves-to-promote-the-ilc-in-japan/ |access-date=2024-10-24 |language=en-US}}</ref> Fifty participants, including Diet members and other government agencies, as well as researchers and businesses, received reports on the project's progress. Participants discussed the ILC's future.<ref name=":1" /> The meeting resulted in three recommendations:

{{Block quote|text=1. The ILC project will be further promoted by the research community, industry, organizations promoting the candidate sites, relevant ministries and agencies, the Diet members and other political organizations within an all-Japan framework. 
2. For the ILC project, international collaboration will be further strengthened as a global initiative involving the research community. This will be achieved through close cooperation between the ILC International Development Team (IDT), an international promotion organization established under ICFA, and the domestic research community. 
3. The Ministry of Education, Culture, Sports, Science and Technology (MEXT) should play an active role in collaborating with the international research community to achieve the global accelerator program. This collaboration should utilize the framework of the Liaison Committee on Future High-Performance Accelerators, in partnership with the Cabinet Office, as well as other relevant ministries and agencies.|author=Federation of Diet Members for ILC|title=Recommendation for the Promotion of the International Linear Collider Project<ref>{{Cite web |date=March 21, 2024 |title=Recommendation for the Promotion of the International Linear Collider Project |url=https://newsline.linearcollider.org/wp-content/uploads/2024/07/Proposal-for-the-Promotion-of-the-International-Linear-Collider-Program-1.pdf}}</ref>}}
