Saburo Tanaka

About

Saburo Tanaka is a leading figure in the development of high-temperature superconducting (HTS) SQUID-based non-destructive evaluation (NDE) systems. His research focuses on creating robust, mobile NDE platforms that can operate in unshielded, real-world environments, a critical challenge for practical industrial applications. Tanaka’s major contributions include pioneering the integration of HTS-SQUID gradiometers and magnetometers onto robotic arms, enabling automated, 3D-mobile inspection of structures. He has advanced sensor design by developing ramp-edge and bicrystal Josephson junctions, and implemented active magnetic shielding using fluxgate sensors to suppress ambient noise. His work has demonstrated the detection of deep-lying defects in materials like aluminum alloys, with key papers accumulating over 50 citations. Notable achievements include the creation of a robot-based NDE system that moves a robust HTS-SQUID magnetometer, covered with an HTS film, for use in unshielded environments—a significant step toward practical, field-deployable superconducting sensors for infrastructure monitoring.
