Abstract
This thesis work, carried out in collaboration with the Institut Néel/G2Elab, Université de Grenoble Alpes, Grenoble, France, is in the context of research on the transition from the superconducting state to the normal state of superconducting materials at high critical temperature (HTS). The study aims to analyze the thermal stability of coils wound with superconducting
tapes for high-field electromagnetic applications. In particular, statistical tools and electrothermal models are used to determine the impact of critical current inhomogeneity of the tape on the thermal stability of such coils. The results of this research will provide insights into improving the design and performance of high-field electromagnets. The objective of this study is to determine the point at which thermal stability breaks down
and thermal runaway occurs. To achieve this, numerical models are used to simulate quench propagation within the coil and to analyze the effect of critical current inhomogeneities on its
thermal stability. The results obtained from this research are of great importance for the development of highfield electromagnets based on HTS superconducting tapes. Indeed, the knowledge of the effect of critical current inhomogeneities on the thermal stability of such coils can lead to improvements in the design and construction of such devices, providing greater safety and reliability during their operation.
