Study and Application of Micrometric Alignment on the Prototype Girders of the CLIC Two-Beam Module

Abstract:

The Compact LInear Collider (CLIC), currently under study at CERN, aims at the development of a Multi-TeV e⁺ e^- collider. The micro-precision CLIC RF-structures will have an accelerating gradient of 100 MV/m and will be mounted and aligned on specially developed supporting girders. The girder fabrication constraints are dictated by stringent physics requirements. The micrometric pre-alignment over several kilometers of girders, allow for the CLIC structures to fulfill their acceleration and collision functionality. Study of such girders and their sophisticated alignment method, is a challenging case involving dedicated mechanical design as well as prototype production and experimental testing.
