Description
Alignment and metrology for particle accelerators and detectors have always been a challenge for surveyors, due to the high number and diversity of components to align, the very specific measurement environment and the non-standard alignment tolerances. This led to the development of new methods and instrumentation, the push for accuracy of the existing ones, and their automation. This presentation will describe the steps needed to perform the alignment of components inside a collider, from the geodetic infrastructure to the final smoothing inside the tunnel. A state of the art of the methods and instrumentation developed will be presented, before setting the directions for the Research and Development for the alignment of future colliders.
