Engineering for ET Complexity Traceability Process
Dive into the model-based systems engineering process for managing time, complexity, and traceability in the context of the ET project. Explore high-level system decomposition, low-frequency interferometer layouts, node integration, and global functional systems. Uncover the intricacies of PBS and WBS structures in the context of HFI and ITF+SE integrated systems.

Systems Engineering process for ET Manage time, complexity and traceability ~ + 2
Lv 1: High-level system - starting the decomposition (PBS) PBS lv.1: ET Civil Infrastructure Noise (fundamental & technical) Electronics Data Service & Support Computing Infrastructure Environmental (clean air, HVAC) Site - Surface Technical Infrastructure Computing Infrastructure Site - Underground HFI LFI Data Processing z Water ingress Fluids x 3 Note: the PBS system decomposition in this presentation serves as an example and does not directly correspond to the latest PBS release (found here)
Lv 2: Low-frequency Interferometer (LFI) optical layout draft 4
Lv 2 (detail): LFI optical layout draft Lv 3: Node Low-Frequency Beam splitter (LBS) Split stabilized LF laser beam into two Fabry-Perot cavity arms 5
Lv 3: Nodes as integrated systems Single node contains complex subsystems (Lv 4): - Payload 5DoF controlled optical elements - Seismic Isolation System (SIS) Float' the payloads - Tower Vacuum System (TVS) Clean and quiet environment Lv 3: Node Low-Frequency Beam splitter (LBS) Split stabilized LF laser beam into two Fabry-Perot cavity arms But also systems serving global functions (Lv 5): - Stray light control (SLC) Reduce light (back)scattering - Wavefront sensing and control Control core optic curvature = Global functions cannot always be satisfied by individual nodes 6
