About

R. Hohmann is a leading figure in the application of high-temperature superconducting (HTS) quantum interference devices (SQUIDs) to non-destructive evaluation (NDE), with a particular focus on aerospace safety. His key research areas encompass advanced sensor development, eddy current testing, and automated inspection systems for critical metallic components. Hohmann’s major contribution lies in pioneering the use of HTS SQUID gradiometers for detecting deep-lying flaws in large aluminum aircraft wheels—a challenge conventional eddy current methods struggle to meet due to signal attenuation. His most cited work, "Aircraft wheel testing with machine-cooled HTS SQUID gradiometer system" (1999, 43 citations), details the development of an automated inspection system capable of reliably finding subsurface cracks and corrosion in wheel drums subjected to extreme dynamic loads. This innovation directly addresses a critical safety need in aviation maintenance. By demonstrating a practical, machine-cooled sensor platform, Hohmann helped bridge the gap between laboratory superconductivity and real-world industrial testing, laying groundwork for modern NDE techniques that enhance both reliability and throughput in aerospace quality assurance.
