A Compact, Low-Cost Atomic Magnetometer

We propose to build prototype magnetometers with sensitivity in the range 1--10 $\mathrmpT/Hz^1/2$ and unit cost of \$2,000, meeting the need for a low-cost system with performance comparable to existing commercial magnetometer systems. The design uses widely-available and low cost components with a design for easy assembly. With its small size, low cost and low power consumption, this system is ideally suited for use on small, disposable UAVs launched through a standard sonobuoy tube. Disposable UAVs may be deployed from a larger high altitude platform and allowed to fly closer to the ocean, providing the maximum possible magnetic signal from underwater targets.
