Scientific project

Introduction to the CLIC project Study for an e- e+ collider with a centre of mass energy of 3 TeV

Sub-µm beam size, down to a few nm at the IP A number of challenges to be mastered, among which:

o Very tight tolerances of alignment of components, to about 10 µm over a distance of 200mo Active stabilization of the quadrupoles in the nanometre range required

Scientific project

Introduction to the CLIC project

Based on a two beam acceleration concept Each linac consists of more than 10 000 modules (with a 2m length)

Scientific project

Introduction to the CLIC project

Different types of components: Quadrupoles :

o MB quadrupoles: ~ 4000 o DB quadrupoles: ~ 42 000

BPM: one per each quadrupole Accelerating structures: ~ 142 800 PETS components: ~ 71 000

Scientific project

Starting point = challenge concerning the pre-alignment of the CLIC components.

Requirements:

Current strategy

Series of steps: fiducialisation of the components and their support, alignment on a common support, alignment in the tunnel using sensors fiducials.

but time and precision consumingconsidering the number of components to be aligned…

The zero of each component will be included in a cylinder with a radius of a few microns:

14 µm (RF structures & MB quad BPM) 17 µm (MB quad) 20 µm (DB quad)

Active alignment consists of two steps: Determination of the position by alignment sensors Re-ajustment by actuators
