The Ubiquitous SQUID: History and Applications

Explore the history and diverse applications of the Superconducting QUantum Interference Device (SQUID) in this 39-minute conference talk by John Clarke from the University of California, Berkeley. Delivered at the APS March Meeting 2018 in Los Angeles, CA, the presentation covers the rapid development of superconducting electronics from 1961 to 1964, including the discovery of magnetic flux quantization and Josephson tunneling. Learn about the SQUID's ultrasensitive capabilities in detecting magnetic flux changes and its adaptability for measuring various physical properties. Discover its wide-ranging applications, from automated measurement systems and geophysical surveys to medical imaging techniques like magnetoencephalography (MEG) and ultralow field magnetic resonance imaging (ULFMRI). Gain insights into the SQUID's role in astronomical research, particularly in cosmic microwave background studies, and its potential in the search for dark matter particles through the Axion Dark Matter eXperiment (ADMX).
