Here we see a team of surveyors from the European Spallation Source ERIC taking precise measurements of a silicon carbide girder prototype at CERN. This activity was part of an Interlaboratory Comparison (ILC), a process recognised by the International Organization for Standardization to ensure measurement consistency and identify potential errors or biases. Precision measurements are crucial for accelerator laboratories. For collisions to occur in the #LHC, the accelerator components must be al
