Description
The Compact Linear Collider (CLIC) study aims at a realistic design of a multi-TeV e+e− linear collider for the post-LHC era of high-energy physics, with the potential to operate at centre-of-mass energies ranging from 380 GeV up to 3 TeV and with luminosities of a few 10^34 cm-2 s-1. It is based on a novel two-beam acceleration scheme and on the use of high-gradient, high-frequency accelerating structures (100 MV/m, 12 GHz). It requires to produce, accelerate and transport over large distances ultra-low emittance beams and focus them to nanometer scale transverse sizes at the collision point.
On top of the technical challenges related to high-gradient and two-beam acceleration, all this implies very tight tolerances in precision machining and pre-alignment of components (of the order of a few um), beam position measurements and damping of vibrations over a few Hertz at the nanometer level, control of stray magnetic field to the nanoTesla and precise synchronization to a few tens of femtoseconds over tens of kilometres. In the presentation we will describe how the CLIC study addressed these difficult issues and review the status of the associated R&D, focusing in particular to the role of the PACMAN project.
