Gravitational-Wave Observatory Configuration Yield Comparator

A tool that compares different designs for gravitational wave detectors to see which one finds more signals.

A hosted decision-support tool that quantifies the science return of candidate gravitational-wave detector designs — such as the Einstein Telescope's triangular single-site versus two L-shaped geometries — so collaborations and funding agencies can compare options on detection rates, source reach, and measurement precision before committing construction funds.

Concept

The Einstein Telescope sits at a real design fork: paper [0] presents state-of-the-art capability predictions for both geometries currently under consideration — a single-site triangular configuration and two L-shaped detectors — and describes open tools built by the ET Collaboration for assessing the scientific potential of different detector configurations. This product wraps that machinery in a comparison-and-reporting service. A user selects or uploads a configuration (geometry, arm length, sensitivity curve, site assumptions) and receives a standardized science-yield card: predicted detection rates by source class, redshift reach, parameter-precision forecasts, and multi-messenger synergy metrics, plus a side-by-side delta report between any two configurations. The single wedge: turning a detector design choice into a quantified, comparable science-return forecast that can be cited in design-freeze and funding documents. It is deliberately not a full simulation suite; it productizes validated, published response functions and rate models behind a decision layer.

Why now

Paper [0] shows the geometry decision is still open — both the triangle and the two-L option are explicitly "currently under consideration" — and that state-of-the-art predictions for both now exist in one place, alongside open ET Collaboration tools for assessing configuration science potential. That means the physics machinery is validated and public, so the cost of productizing it is low, while the audience is concrete and near-term: the European project is moving through design and funding stages, and the US Cosmic Explorer project faces analogous arm-length and site choices. No existing catalog idea serves pre-construction observatory design trade-offs.

AI assessment

Backed by 1 paper89

A highly focused decision-support tool for a niche but high-stakes 'big science' market, leveraging existing validated physics models to resolve a specific design fork.

Evidence strength
5/5
The idea directly maps to the findings of paper [0], which explicitly provides the capability predictions for the two specific geometries currently under consideration for the Einstein Telescope.
Market pull
3/5
The buyer pool is extremely small (a few global funding agencies and collaborations), though the urgency and budget per decision are exceptionally high.
Novelty & moat
5/5
Unlike the catalog's existing GW tools which focus on post-event analysis, this is a pre-construction design tool, filling a distinct gap in the infrastructure planning phase.
Feasibility
4/5
Since the physics machinery and open tools already exist within the ET Collaboration, the MVP is primarily a UI/UX wrapper and reporting layer rather than new scientific discovery.
Wedge clarity
5/5
The wedge is incredibly sharp: providing a standardized 'science-yield card' to resolve the specific triangle vs. L-shape design choice.
Simplicity / focus
5/5
The product avoids 'platform creep' by focusing strictly on a comparator for design configurations rather than attempting to be a full simulation suite.

Who benefits

  • Einstein Telescope Collaborationorganization

    It is actively weighing the triangular versus two-L geometries; a standardized, citable science-yield comparison directly supports its design-freeze decision.

  • Cosmic Explorerorganization

    The US third-generation detector project faces its own arm-length and site configuration choices; the same comparison service generalizes to its design studies.

  • INFN (Istituto Nazionale di Fisica Nucleare)organization

    A leading ET stakeholder backing the Sardinia candidate site; quantified science-per-configuration strengthens its national funding and siting case.

  • Nikheforganization

    The Dutch institute coordinating ET contributions can use yield comparisons in project planning and multi-year proposals.

  • STFC (Science and Technology Facilities Council)organization

    The UK funding agency evaluating ET investment needs science-return-per-configuration analysis to build its business case.
