Description
The Einstein Telescope (ET) aims for an order-of-magnitude improvement in strain sensitivity and an extended low-frequency range compared to current Gravitational Wave (GW) detectors [1]. This ambition presents major challenges for the design of the large-scale technical infrastructure supporting the facility.
Given the strong overlap in technologies and engineering approaches developed for particle accelerators such as the LHC and the FCC, CERN and ET have formalised collaboration agreements to share expertise and contribute to the technical design of ET. This poster presents recent CERN contributions in Electrical (EL), Cooling and Ventilation (CV), and Access and Alarms (AA) systems, specifically developed for the baseline ET triangular configuration.
The contribution of this work is threefold:
i) it outlines the design approach and key preliminary results;
ii) it identifies high-level technical requirements for system integration, spatial integration, performances, safety and scheduling;
iii) it highlights how lessons learned from existing GW detectors have been incorporated into the current design.
The EL team presents a preliminary load mapping of the facility and the optimisation-oriented approach used to assess various grid backbone concepts. The CV team addresses the complexity of the installation by focusing on a representative subsystem and formulating a scalable system architecture. The AA team contentrates on access control and hazard detection strategies, enabling safe and controlled operation of the underground premises while supporting emergency response.
The proposed poster offers one of the first cross-domain design perspectives of ET technical infrastructure systems (EL, CV, AA), combining system-level requirements with lessons learned from existing detectors.
