FCCとはFuture Circular Colliderでいまの巨大加速器LHC(large hadron collider)を
入射器としたさらにおおきなシンクロトロンのことだ。
次世代の加速器はILC(international linear collider)かとおもっていたがなにやら
雲行きが変わっていきそうな気配だ。
これはCERNの計画であるのにアメリカのワシントンで開かれるのが変だ。
それにハドロンcolliderではじめるのではなくFCC-ee電子陽電子衝突器で始めるのも
ILC計画と正面からぶつかることになる。
エネルギーは９０から４００GeVなのでILCと重なる。
FCC-ee
The FCC-ee in a few words
The FCC-ee, formerly known as TLEP, is a high-luminosity, high-precision e+e- circular collider envisioned in a new 80-100 km tunnel in the Geneva area. With a centre-of-mass energy from 90 to 400 GeV, the physics program could pave the way towards the discovery of physics beyond the Standard Model, casting light on unanswered questions, such as dark matter, the baryon asymmetry of the Universe, the hierarchy problem, the stability of the Universe or the nonzero neutrino masses.
The FCC-ee project is part and parcel of the Future Circular Collider design study (FCC) at CERN, and would be the first step towards the long-term goal of a 100 TeV proton-proton collider. It is expected to deliver its conclusion in 2018, just prior the next update of the European Strategy. There are many challenges facing the study, starting with a realistic design that allows these promises to be fulfilled, so feel free to join the design study group if you wish to collaborate with us!

ワシントンでの会議はあまりオープンにはなっておらず
政治的な要素が臭う。
