Description
To satisfy its science case, the Einstein Telescope (ET) is required to supersede the sensitivity of current-generation detectors by several orders of magnitude, depending on the frequency range. On top of this and by nature of design, interferometry-based gravitational wave detectors provide an extraordinary challenge of system functional and physics-driven interconnectedness. Complex and highly integrated subsystems distribute the high-level system functions over large spatial distances and with great interdependency, achieving optimal detector sensitivity only when all critical distributed and integrated subsystems work together in unison.
A thorough understanding and documentation of detector subsystem components and their interfaces, requirements and spatial dependencies is therefore imperative. In addition to this, proper spatial and functional integration of the detector with its surrounding underground civil and technical infrastructures will be necessary to improve both the accuracy of research infrastructure costing exercises, as well as the reduction of harmful self-induced infrastructure technical noises.
This contribution will highlight the importance of establishing and continuously managing a common design baseline, with the aim of improving data availability, correctness and development speed. Both past and future development steps will be discussed, and particular attention will be placed on the proposed transition from legacy data - acquired during the 2023-2024 Product Breakdown Structure (PBS) campaign and 2025 Design Task Force - to a future shared framework, considering tools, resources and processes to be established.
