At CERN, the European Organization for Nuclear Research, physicists and engineers are probing the fundamental structure of the universe. Using the world's largest and most complex scientific instruments, they study the basic constituents of matter - fundamental particles that are made to collide together at close to the speed of light. The process gives physicists clues about how particles interact and provides insights into the fundamental laws of nature.

The Beams Department is at the heart of the CERN accelerator complex and plays a key role in providing the world-class scientific instrument needed by the Physics community. Amongst other things, we are responsible for the construction and installation of key components, exploitation of the whole complex and technical infrastructure.

The Geodetic Metrology group https://be-dep-gm.web.cern.ch/ provides metrology and alignment for all components installed in the accelerators, their beam transfer lines and the physics experiments throughout the CERN complex and handles the geodetic reference aspects of the CERN reference systems.

The ASG (Accelerator Survey & Geodetic measurements) section is responsible for the geodetic and large-scale metrology measurements as well as the alignment of the accelerator components and their associated beam transfer lines for the whole CERN site. Furthermore, the ASG section is in charge of the acquisition and processing of high-accuracy point cloud data defined in the primary CERN reference frame (CCS).
