The European Organization for Nuclear Research, also called the European Laboratory for Particle Physics and commonly referred to by the acronym CERN (from the initial name of the European Council for Nuclear Research, a provisional body established in 1954), is the largest center of particle physics of the world.

It is located a few kilometers from Geneva, straddling the Franco-Swiss border, mainly in the communes of Meyrin (canton of Geneva) and Prévessin (France, Ain). All of the installations include more than 120 km of particle beams, oriented by magnets and equipment, positioned, aligned and smoothed by surveyors.

CERN is a legendary place for surveyors where we meet alignment requirements to tenths of a millimeter over hundreds of meters of installation; “a real boulevard of space” for physicists.

The office, with its partners, was the winner of the first two global calls for tender, between 1997 and 2000. In 2024, with these same partners, Geotop and Hyp-Arc, Haller Wasser returns to CERN for a new contract. industrial support in terms of alignments.

Around twenty people on average carried out on-site measurements for the implementation of a multitude of particle detection and guidance elements.

An associate of the management developed, during his internship as a surveying engineer, the first version of the Géode database of the Survey group, managing all of the geometric elements constituting the various CERN accelerators, while another of our engineer has worked for more than 15 years, devoting a large part of his activity to the operation and development of these databases, particularly during the construction of the LHC.
