Postdoctoral Researcher

The Department of Physics and Astronomy at the University of Turku invites applications for a fixed-term Postdoctoral Researcher position in the SmartHiTS project. The researcher will develop finite-element and multiphysics models to support the design of intrinsically safer high-temperature superconducting conductors and coils. The employment is a two-year fixed-term position, reflecting the expected duration of the project's main modelling activities. The preferred start is as soon as possible or as agreed. About the SmartHiTS project High-temperature superconductors such as YBa2Cu3O7-delta (YBCO) enable compact, energy-efficient magnets for fusion reactors, particle accelerators, magnetic resonance imaging, and energy-storage systems. A sudden loss of superconductivity, known as a quench, can nevertheless cause rapid overheating and catastrophic coil failure. SmartHiTS aims to develop self-protecting YBCO tapes whose microstructure and conductor architecture are deliberately engineered to control and mitigate quench behaviour. The project links microscopic material properties to macroscopic quench dynamics through thin-film growth, advanced characterization, cryogenic testing, multiphysics modelling, and prototype validation. It will investigate varied YBCO microstructures and current-diverter concepts, develop predictive FEM and machine-learning surrogate models, and support the upscaling of prototype tapes with collaborators. Role and research focus The postdoctoral researcher will lead the project's FEM and multiphysics simulation activities, working in close collaboration with experimental researchers. The principal objective is to develop and validate models that reveal how material properties, interfaces, and conductor architectures influence quench initiation, current redistribution, thermal propagation, and protection performance. The role contributes centrally to the project's modelling work package and connects it to the experimental development of current diverters and to prototype-scale validation. The researcher will also act as the principal scientific contact with Quanscient Oy and participate in international collaborations. Main responsibilitiesdevelop, implement, and document FEM and multiphysics models for quench behaviour in YBCO high-temperature superconducting tapes and coils;parameterize and validate models using data generated by the project's experimental work packages;simulate current diverters;identify conductor and wire architectures that prevent quenches or reduce their consequences;analyse simulation results, quantify uncertainty and limitations, and translate findings into experimentally testable design recommendations;work closely with experimentalists and prototype collaborators throughout model development and validation;serve as the project's main scientific contact with Quanscient;prepare high-quality scientific publications and present results at international meetings; andcontribute, where appropriate, to supervision of doctoral and master's students. Expected outputsvalidated FEM and multiphysics models linking YBCO material parameters and conductor architecture to quench behaviour;design rules and optimized superconducting-wire structures for quench prevention, mitigation, and self-protection;simulation evidence supporting the experimental selection of current-diverter architectures;documented, reproducible modelling workflows and datasets suitable for later surrogate-model development; andpeer-reviewed publications and contributions to project reporting and dissemination.
