The exploration of superconducting coils has found that these materials have many applications from MRI machines to particle accelerators. The lack of electrical resistance in these materials is the most interesting and important factor in these applications. These materials must be able to be monitored, though for failure, otherwise known as quench state. If the superconductor reaches a quench state, the material could lose its lack of resistivity and therefore damage the materials. Methods that have been used to detect failure in other low temperature superconducting (LTS) materials cannot be used in high temperature superconducting (HTS) materials. Optical fiber sensors are promising as a failure detection method for HTS materials. This thesis explores the these optical fiber sensors as a failure detection method in superconducting coils.
