Welcome to the Lepton Collider Platform Twiki

Introduction

This TWiki is associated to the Lepton Collider Platform that aims at sharing information among participants in e+e- collider studies. The platform serves as a collaborative tool and was created in the framework of Work Package 7 (WP7) of the EU-funded Cremlin project in order to share common experiences, software applications and hardware solutions. The participating institutes of WP7, Budker institute (BINP) and CERN, are both pursuing design studies for future e+e- colliders (SCT, FCC-ee and CLIC). The platform can serve the wider e+e- collider community.

The Facilities

CLIC

The Compact Linear Collider (CLIC) is a concept for a machine to collide electrons and positrons at energies up to several TeV. The aim is to use radiofrequency structures and a two-beam concept to produce accelerating fields as high as 100 MV per metre to reach a nominal total energy of 3 TeV, keeping the size and cost of the project within reach.

FCC-ee

The design of the circular Future Circular Collider (FCC), with a circumference of 80-100 km, covers options for hadron-hadron (hh), electron-positron (ee) and electron-hadron (eh) collisions. The FCC-ee accelerator study foresees electron-positron collisions at ~350 GeV, 240 GeV, 161 GeV and 91 GeV. The luminosity performance of FCC-ee increases with decreasing centre-of-mass energy from 1.3*10^34 cm-2s-1 at 350 GeV to 90*10^34 cm-2s-1 at 91 GeV per interaction point. The baseline design currently foresees two interaction points.

SCT

The Super-Charm-Tau (SCT) factory is an electron-positron collider being developed in Budker Institute of Nuclear Physics (Siberian Branch, Russian Academy of Sciences) in Novosibirsk. The collider will operate in a range of centre-of-mass energies from 2 to 5 GeV at an extremely high luminosity of 10^35cm-2s-1 with longitudinal electron polarization at the interaction point. The SCT facility foresees a two-ring collider in which a Crab-Waist scheme is used to obtain such a high luminosity.
