Abstract
Ultra-sensitive Superconducting Quantum Interference Device (SQUID) sensors, which are critical components of key experiments in nuclear physics, are the most sensitive detectors of magnetic flux available. However, currently available SQUID readout electronics are extremely dated in terms of component availability, ultimate performance, and data acquisition and computer interface options. This project will develop next-generation flux modulation-based SQUID readout electronics. A novel, modular design will provide excellent flexibility for a wide variety of multi-­channel applications to ensure the highest possible noise immunity for critical low-noise measurement applications. In Phase I, prototype SQUID electronics with a USB 2.0 computer interface was designed, built, and tested. The system bandwidth was much higher than any known modulation-based electronics that is currently available. Phase II will complete the development of a multi-channel SQUID readout electronics based on the Phase I designs, along with new, high-performance SQUID sensors, a precision optically-isolated data acquisition unit, and control software.Commercial Applications and other Benefits as described by the awardee: Beyond the application to nuclear physics, a complete SQUID-based readout electronics system should find use in a broad range of commercial applications including biomedical imaging (e.g., magnetoencephalography and magnetocardiography), geophysical exploration (e.g., for oil and mineral exploration, and to analyze core samples), and non-destructive testing of materials (e.g., detection of impurities and contaminants in food).
