The Compact Linear Collider (CLIC) project explores the possibility of constructing a future multi-TeV linear electron-positron collider. The CLIC-concept is based on high gradient normal-conducting accelerating structures. The RF power for the acceleration of the colliding beams is produced by a novel two beam acceleration scheme, where power is extracted from a high current drive beam that...

Future lepton colliders such as the International Linear Collider (ILC), and the Compact Linear Collider (CLIC)
require nanometer-sized beams at the interaction point (IP). We report on the design, protoyping and testing
of beam-based feedback systems for steering the beams into collision at the IP so as to maximise the luminosity
performance of the colliders. Both all-analogue and digital...

Beam polarisation is an important ingredient of the physics progam of
future Electron Positron Linear Colliders. In order to fully exploit the benefits of the polarised beams, the luminosity weighted average polarisation needs to be known to 0.25% or even 0.1% at the ILC, while a few percent seem achievable at CLIC. We will present the polarimetry concept for the Beam Delivery Systems of both...
