TEMO (Tokamak Equilibrium Modeling toolbox for Operation) is an operation-oriented tokamak equilibrium toolbox that covers the entire experimental workflow, from discharge design to analysis. It supports full closed-loop simulation of the evolution, observation, and control of both singlet/doublet configurations, providing strong support for discharge design, controller design, diagnostic data processing and physics experiment analysis during experimental operations.
Features
Supports three self-consistent and high-fidelity equilibrium computation methods, including equilibrium reconstruction, forward free-boundary calculations, and coil-current reconstruction.
Supports feedforward design and various feedback-control simulation functions. Based on the feedforward design, it produces a feasible discharge scenario. Feedback-control simulations are carried out based on plasma response model to investigate plasma-control strategies, providing a basic plan for control experiments.
