Predicting MANTIS performance in W7-X: Synthetic Modeling of the Expected Operational Regime Using EMC3-EIRENE — •Joey Louwe1, Felix Reimold1, Valeria Perseo1, Victoria Winters1, Nassim Maaziz1, Alexander Knieps2, Henry Greve1, Mohammad Foisal Siddiki1, and W7-X team1 — 1Max Planck Institute for Plasma Physics, 17491 Greifswald, Germany — 2Forschungszentrum Jülich GmbH, Institute of Fusion Energy and Nuclear Waste Management*Plasma Physics, 52425 Jülich, Germany
Modern large-scale magnetic confinement fusion devices use divertors to optimize particle and heat exhaust. At the Wendelstein 7-X stellarator (W7-X), this is achieved with an Island Divertor concept, where magnetic islands guide particles and heat along field lines to dedicated target plates. Due to its 3D geometry, diagnosing transport across the island is challenging with existing diagnostics. To address this, the new MANTIS imaging system will be combined with helium gas puffs in upcoming campaigns to provide localized measurements of island plasma parameters and infer transport dynamics. Simulation studies using the EMC3-EIRENE plasma fluid transport code were conducted and a new synthetic forward modeling tool to assess MANTIS performance and operational viability was developed. These predictions, informed by existing W7-X data (helium puff spread, electron temperature, and density profiles), enable optimized MANTIS system design and deployment. This contribution presents simulation results, MANTIS performance predictions, and its current integration status.
