Digital SQUIDs hit the road

Pascal Febvre, a researcher at IMEP-LAHC and the University of Savoie, has outlined a superconductivity roadmap for digital SQUIDs, or superconducting quantum interference devices. His roadmap was published in Superconductor Science and Technology and focuses on two applications: detecting solar bursts—which are highly disruptive to space communications—and earthquakes.
Pascal’s research team at the University of Savoie already helps operate the world’s only two SQUID-equipped research centers. They are also working to develop SQUIDs with fully digital signal processing capabilities and advanced dynamic performance. They eventually hope to be able to detect magnetic fields less than one femtotesla strong—that’s even weaker than the field emitted by our brains when we’re sleeping!
