Fusion Twin Platform
The primary goal of the Fusion Twin Platform, fusiontwin.io, is to streamline and accelerate the entire experimental process on tokamaks—from preparation and execution to analysis and sharing—thereby reducing the time to scientific insight and publication.
A key feature of the platform is its expanding collection of digital replicas of existing, past, and future tokamaks, available for running precise simulations using NSFsim. These simulations provide comprehensive modeling of plasma behavior under various conditions, addressing the complexity of fusion simulations and the industry’s limited access to public data.

Digital Replicas
To make reliable and realistic simulations, we couple NSFsim, our simulator, with digital replicas of tokamaks. Every replica is a unique mathematical abstraction of a tokamak, including its diagnostics and sensors. The digital replicas of DIII-D, ISTTOK, and other upcoming tokamaks are available on the platform for all users.Configurable Simulations
Platform users can not only choose between different types of simulations but also configure details such as initial plasma geometry and parameters, coefficients for tuning specific mathematical equations, magnetic field control options, the time step, and the number of simulation steps, including specific input signal parameters for each step. To simplify onboarding and adoption, each simulation type comes with a detailed initial configuration that users can modify.Flexible Visualization
The simulation results are saved in one of the fusion industry’s widely used formats, Hierarchical Data Format version 5 (HDF5), and can be downloaded or immediately browsed using the platform’s visualization and data management tools. The Graphs tool offers more than one hundred pre-defined graphs for all major plasma parameters and diagnostic signals, allowing flexible work with multiple graphs simultaneously.Collaborative Features
The Next Step Fusion team has envisioned an extensive roadmap of features that includes adding new digital replicas of tokamaks, integrating additional scientific codes for better simulations, and many others. Among the next high-priority items are enhancements to collaboration and sharing features, aimed at enabling faster and easier communication between fusion teams.
