Abstract

The Compact Linear Collider (CLIC) is a high energy electron–positron collider with a maximal centre-of-mass energy of 3 TeV. In order to achieve high luminosity small bunches with high intensity are necessary. These lead to strong beam-beam forces, which create a challenging background environment. The accelerator concept and the detectors designed for CLIC are presented. Results from detector benchmark studies presented in the CLIC conceptual design report are summarised.

Highlights

  • A high-luminosity and high-energy electron–positron collider allows for precise measurements of Standard Model and Beyond Standard Model physics

  • Key issues have been identified in the accelerator Conceptual Design Report (CDR) for Compact Linear Collider (CLIC), and feasibility was successfully shown in CLIC Test Facility 3 (CTF3) and elsewhere

  • It has been shown that drive beam generation and two-beam acceleration is possible

Summary

Introduction

A high-luminosity and high-energy electron–positron collider allows for precise measurements of Standard Model and Beyond Standard Model physics. The Compact Linear Collider (CLIC) is designed for electron–positron collisions at centre-of-mass energies of up to 3 TeV, and is offering a possible physics reach complementary to that of the LHC. In 2012 a Conceptual Design Report (CDR) for the CLIC accelerator, detailing the technological feasibility issues, will be published [1]. The report concentrates on a machine optimised for 3 TeV. The preferred energy, from a physics pointof-view, will be determined largely based on the results from the LHC. The feasibility of a detector operating in the conditions of the CLIC collider has been evaluated in a separate CDR volume [2]
