２００４年のノーベル物理学賞を受賞した米カリフォルニア大のデビッド・グロス教授（７２）＝理論物理学＝が２１日、仙台市を訪れ、超大型加速器「国際リニアコライダー（ＩＬＣ）」の構想実現に期待感を示した。(David Gross, the winner of the 2004 Nobel prize in physics, visited Sendai city on 21 October, and express his expectation on the realisation of the ILC)

子どもたちが宇宙の成り立ちやＩＬＣ＝国際リニアコライダーの役割について学びました。盛岡の城北小学校の5、6年生、およそ240人に授業を行ったのは、ドイツの国立マインツ大学で物理学を専門とする齋藤武彦教授です。( About 240 elementary school children in 5th and 6th grade learned about the ILC from Takehiko Saito of Johannes Gutenberg University Mainz, Germany)

Fundamental physics seems to have an insatiable appetite for bigger, more expensive machines. There may, though, be a way to shrink them radically

ディレクターのリン・エバンス氏らが奥州市のホテルで記者会見し、「候補地の選択は適切だ。北上山地に合わせて詳細な設計を進める。日本政府のはっきりした意思表明が必要」と強調した。(Lyn Evans said in the press conference that the Kitakami is suitable for ILC construction, and will start the site specific design. What we need is a statement from the Japanese government)

ＩＬＣ＝国際リニアコライダー計画を進める国際的研究者組織の幹部が、きょう建設候補地である岩手の北上山地を初めて視察しました。（Executive members of the Linear Collider Collaboration visited Kitakami mountains, the ILC candidate site, on 17 October)

国際リニアコライダー（ＩＬＣ）計画の学術的意義や科学技術立国への新たな道筋について考えるシンポジウムが１５日、東京大学で開かれた。(The symposium to discuss the road map toward the realisation of the ILC was held on 15 October in Tokyo)

Many believe accelerator physics still has an important role to play, such as with a linear collider that will by necessity be a worldwide effort. “I do not believe that we can make significant progress without also pushing back the frontier of high energy,” Nobel laureate Steven Weinberg wrote in an essay titled “The Crisis of Big Science” in The New York Review of Books last year. “So in the next decade we may see the search for the laws of nature slow to a halt, not to be resumed again in our lifetimes.”

“avec des collisionneur linéaires, on pourrait presque faire une “usine à bosons de Higgs” – en produire en très grande quantité, observer toutes leurs façons de se désintégrer en d’autres particules et faire une métrologie exrêmement précise, qui permettra de le caractériser complètement” (video interview of Etienne Klein)

“That would be absolutely amazing because the ILC is a whole different kind of machine than the LHC. It collides electrons with positrons [their antimatter twins], which produces very clean collisions. You can do precision measurements of the kind you can’t even think about at the LHC. So if you can produce dark matter at the ILC, then it will become the dark matter factory for the next 30 years. That’s the way we’re going to figure out what the dark universe is all about.”

According to Hitoshi Murayama, director of the Kavli Institute for the Physics and Mathematics of the Universe in Tokyo, who sat on the international review committee, there are about 150 people in the Japanese Congress who actively support the ILC and in July the ruling party LDP published a policy document that mentioned the ILC. However, supporting the ILC is not yet an official position of the government, with the Japanese Ministry of Education, Culture, Sports, Science and Technology waiting for a decision.
