Superconducting joint techniques for the magnets applications

Professor Dr. Canan Aksoy

Abstract:

Superconducting magnets are critical to in the design of nuclear magnetic resonance (NMR) and magnetic resonance imaging (MRI) scanners, besides high field experiments such as the Large Hadron Collider (LHC) and the upcoming International Thermonuclear Experimental Reactor (ITER). Superconducting solders are used for integrating superconducting wires and magnets. The magnet’s terminals must be connected in order to confine the super current to the circuit. The currently used PbBi and PbSn solders are costly and non-environmental friendly. In the European Union, Restriction of Hazardous Substances (RoHS) legislation for electrical and electronic equipment banned to use of Pb in electronic devices after July1, 2006. Thus, lead free materials and techniques have been investigated by researchers for many years such as: soldering joints with Pb-free solders, cold pressing and spot welding. The microelectronics packaging and aerospace industries now rely on AgCuSn solder joints for the robust mechanical attachment and electrical interconnection of a wide variety of components. This talk will be related on the HTS and LTS joint techniques for the Magnet applications.

Canan Aksoy Bio:

Canan Aksoy has trained as a Physicist at the Science Faculty of Karadeniz Technical University (Trabzon, Turkiye), and was awarded a PhD in 2012 from the same University for “Fluorescence Parameters of Some Elements and Their Compounds and Structural Analysis of FeySe1-xTex Superconducting Thin Films”. During her PhD research, she has been a researcher (9 months) in Superconductivity group at the Department of Materials in The University of Oxford. She has worked as an Assistant Professor in the Avrasya University, Trabzon for 2 years. She was awarded an International Postdoctoral Research Fellowship from TUBITAK for the Department of Materials in The University of Oxford to do research on Superconducting Joints. She has started to work for Karadeniz Technical University in 2015 and She has been working as an Associate Professor and Head of Department of Electronics and Communication Department of Karadeniz Technical University. She has around 40 indexed papers, more than 60 conference letters and 2 book chapters. She organized COST 2. Hi-Scale training school and EUCAS 2023 short courses in 2023. Currently, she has been working on LTS, HTS and MgB2 joint design and fabrication for the magnet applications and radiation shielding properties of materials.
