Federico joined Schwartz group in 2014 first as a visiting scholar and then as a Ph.D. student. His scientific interests regard High Temperature Superconductors (HTS) and currently focus on the development of innovative quench detection techniques, primarily based on fiber optic systems.
Federico’s current research project is about HTS-based superconducting magnets quench detection. Nuclear fusion technology, high energy particle physics, power transmission, energy storage, magnetic resonance imaging are some of the fields where superconducting materials play a crucial role. They would all benefit from the use of HTS materials. However one of the unsolved issue that prevents the use of HTS materials from becoming widespread is their quench protection. Federico is developing and investigating a novel quench detection system based on the use of optical fibers as distributed sensors. The measurement system takes advantage of Rayleigh back-scatterings that occur in optical fibers to estimate quantities related to temperature and strain. Thanks to a high spatial resolution and quick measurement, normal zones can be detected and localized and their size monitored in time. These features, along with an understanding of the minimum propagating zone (MPZ) enables a new simple quench detection logic, based on the size of the MPZ instead of a threshold voltage.
