Description
About the lecture:
Quench localization is a diagnostic technique used to support the development and testing of superconducting accelerator magnets. The accurate identification of the quench origin, when combined with other diagnostic methods, helps determine the possible causes of performance limitations and contributes to improving magnet design and development. Quench antennas are advanced magnetic sensors designed to detect the magnetic field perturbations caused by a quench. They typically consist of arrays of pickup coils distributed along the magnet, capable of capturing the fast and tiny magnetic transients that occur at quench onset. The resulting signals can be used to reconstruct the quench initiation position with high temporal and spatial resolution. The sensitivity design of the sensors determines the accuracy and robustness against noise. This lesson presents the basic design principles of quench antenna sensors, along with examples of their application in real cases.
About the speaker:
Lucio Fiscarelli is an electronics engineer at the European Organization for Nuclear Research (CERN) in Geneva, Switzerland. He holds a PhD in Information Engineering with a focus on magnetic measurements from the University of Sannio. He is member of the Magnets, Superconductors, and Cryostats (MSC) group within CERN’s Technology Department (TE), where he works on magnetic measurements and instrumentation for the test and characterization of magnets used in particle accelerators. His activities include the design and implementation of advanced magnetic measurement systems, such as rotating coils and quench antennas, in support of several projects, including the High-Luminosity LHC (HL-LHC) upgrade and the High Field Magnets (HFM) program.
