FCC-ee: The Lepton Collider (original) (raw)

The International Linear Collider

International Journal of Modern Physics A, 2013

In this paper, we describe the key features of the recently completed technical design for the International Linear Collider (ILC), a 200–500 GeV linear electron–positron collider (expandable to 1 TeV) that is based on 1.3 GHz superconducting radio-frequency (SCRF) technology. The machine parameters and detector characteristics have been chosen to complement the Large Hadron Collider physics, including the discovery of the Higgs boson, and to further exploit this new particle physics energy frontier with a precision instrument. The linear collider design is the result of nearly 20 years of R&D, resulting in a mature conceptual design for the ILC project that reflects an international consensus. We summarize the physics goals and capability of the ILC, the enabling R&D and resulting accelerator design, as well as the concepts for two complementary detectors. The ILC is technically ready to be proposed and built as a next generation lepton collider, perhaps to be built in stages begin...

The LHC Experimental Programme

Europhysics News, 1992

Crucial to our understanding of one of the most fundamental problems in par ticle physics-the origin of electroweak symmetry breaking-will be to cross the 1 Tev frontier for constituent colli sions at the Large Hadron Collider (LHC) proposed as CERN's next accelerator facility. In making extensive use of exis ting infrastructure-the Large Electron Pro ton (LEP) collider tunnel and other parts of CERN's accelerator complex-the LHC will be an extremely cost-effective way to provide several unique but complemen tary physics options up to energies of almost 16 TeV and luminosities exceeding 1034/cm2s. LHC will extend CERN's tra dition of providing its user community with state-of-the-art facilities which would span a broad diversified physics programme well into the next century.

The International Linear Collider. A European Perspective

2019

The International Linear Collider (ILC) being proposed in Japan is an electron-positron linear collider with an initial energy of 250 GeV. The ILC accelerator is based on the technology of superconducting radio-frequency cavities. This technology has reached a mature stage in the European XFEL project and is now widely used. The ILC will start by measuring the Higgs properties, providing high-precision and model-independent determinations of its parameters. The ILC at 250 GeV will also search for direct new physics in exotic Higgs decays and in pair-production of weakly interacting particles. The use of polarised electron and positron beams opens new capabilities and scenarios that add to the physics reach. The ILC can be upgraded to higher energy, enabling precision studies of the top quark and measurement of the top Yukawa coupling and the Higgs self-coupling. The international -- including European -- interest for the project is very strong. Europe has participated in the ILC pro...

The Large Hadron Collider-present status and prospects

IEEE Transactions on Appiled Superconductivity, 2000

The Large Hadron Collider (LHC), due to be commissioned in 2005, will provide particle physics with the first laboratory tool to access the energy frontier above 1 TeV. In order to achieve this, protons must be accelerated and stored at 7 TeV, colliding with an unprecedented luminosity of 10 34 cm-2 s-1. The 8.3 Tesla guide field is obtained using conventional NbTi technology cooled to below the lambda point of helium. Considerable modification of the infrastructure around the existing Large Electron Positron collider (LEP) tunnel is needed to house the LHC machine and detectors. A brief status report is given and future prospects are discussed.
