This thesis explores the integration of Fiber Bragg Grating (FBG) optical fibers as an innovative solution for quench detection in high-temperature superconducting (HTS) cables, specifically within a 6-slot aluminum core design for fusion applications developed at ENEA. HTS materials, such as REBCO, are known for their high critical parameters but present challenges in quench detection due to their low normal zone propagation velocity (NZPV). Traditional voltage-based quench detection methods are less effective under these conditions, necessitating alternative solutions. In this study, an HTS cable utilizing a BRAided STack (BRAST) of YBCO tapes was fabricated and tested, incorporating FBG sensors within steel capillaries placed directly onto the stack.
