Fast Field Mapping of Large Size Bulk Superconductors at Variable Temperatures and Magnetic Fields

The present paper deals with the development of a costumed-made system and techniques to address the challenges of the magnetization and characterization of bulk superconduc tors as large as 100 mm in diameter. The system is composed of a dry superconducting magnet capable of producing a field variation up to 18 T and a measurement setup relying on an advanced field mapping arrangement made of a 10 × 10 Hall sensor matrix for rapid magnetic field acquisition under 0.5 s. To achieve the desired accuracy, the experimental setup incorporates precise thermal management and calibration. Its purpose is to investigate strategies to enhance the stability, structural integrity, and overall performance of superconducting bulk materials magnetized in high magnetic fields. The goal is to promote scientific collaborations through a dedicated experimental facility for forthcoming magnetization and fast field-mapping studies, thereby supporting the development of bulk superconductors.
