Precision Pointing and Stability Control of the Future Linear Collider Quadrupoles

摘要

This paper presents a simple model of the future linear particle collider CLIC. Adopting an integrated approach, it is proposed to merge the controller of the beam of particles and the controller of the sensitive electromagnets into a single controller, allowing interactions between the two subsystems, and performances optimization. The interest of such an approach has been confirmed by experimental results, showing that the same supports can be used alternatively to stabilize the electromagnets, or to re-align them with a nanometer precision.
