Description
The Tuscia Research University Small Tokamak (TRUST) is a compact university-scale device currently under design at Università degli Studi della Tuscia. Conceived as a flexible and cost-effective platform, TRUST supports education, technology development, and physics studies of relevance to next-generation fusion devices. The conceptual design foresees a baseline single-null configuration with R₀ = 0.3 m, Iₚ = 110 kA, Bₜ = 0.8 T, and aspect ratio A = 2.5, while allowing access to double-null and upper single-null magnetic topologies. Its modular architecture enables straightforward integration of innovative components and future upgrades.
In this work, finite-element (FEM) models of several magnetic configurations for TRUST are developed using the MAXFEA code. A preliminary arrangement of magnetic probes and flux loops is considered, and synthetic magnetic measurements are used together with the EFIT equilibrium solver to investigate the reconstruction capability over different plasma scenarios. The comparison across configurations allows evaluating the consistency between the magnetic layouts and the proposed diagnostic set.
The results represent an initial indication of the reconstruction performance achievable in a TRUST-like device and offer general guidance for the progressive refinement of the magnetic diagnostic system as the design of the machine evolves.
