Description
The Einstein Telescope's unprecedented scale and precision requirements demand a robust spatial integration strategy from the earliest design phases. This presentation outlines the 3D integration framework being developed within ETO's Engineering Department, covering the definition and management of spatial envelopes, coordinate systems, and the treatment of slope and tilt constraints across the underground infrastructure.
A central challenge is reconciling distributed technical infrastructure — spanning kilometres of tunnel — with localised installations at the detector stations, while preserving the geometric precision required for interferometer alignment and ensuring adequate clearances for laser beam paths. We present our approach to integrating local infrastructure models into the general 3D layout without sacrificing the level of detail needed at critical interfaces, and discuss how alignment procedures inform envelope definitions and positional tolerances.
Delivering on this strategy requires close and sustained collaboration with the Einstein Telescope Collaboration (ETC). The subsystem designs, interface definitions, and spatial requirements originate from the instrument and infrastructure groups within the ETC, and their early involvement is essential to converge on realistic envelopes and integration constraints. This presentation is therefore also an invitation to establish joint working structures.
The presentation also addresses the practical dimensions of integration: logistics path planning through the underground facility and the definition of spatial responsibilities across Subject Matter Expert (SMEs). We outline the proposed governance structure, including dedicated integration meetings, engineering change request workflows, and configuration and interface management processes — all essential to coordinate the contributions of a growing collaboration.
