Robot to mark the way: robotic tracing to support HL-LHC installation
The CERN Survey team (BE-GM-ASG) took a major step towards modernising how floor markings are performed in the LHC tunnel, with the introduction of the HP Site Print tracing robot. This new solution will play a key role in preparing for the installation of HL-LHC components.

Production of the first HL-LHC jacks units in Serbia
Production of the first HL-LHC jacks units in Serbia By Prof. Peter Adzic and Beniamino di Girolamo Validation loading tests for the first HL-LHC jacks produced by UNIOR components d.o.o, a Serbian Company. They are part of an order for nineteen longitudinal jacks and four central jacks that will be used to support the magnets in

Aligning the HL-LHC magnets with interferometry
Aligning the HL-LHC magnets with interferometry CERN surveyors have just finalised a system that can determine, in real time, the position of certain components inside the (sealed) cryostats of the future High-Luminosity LHC (HL-LHC). Read more Read more news
