Abstract
We describe a portable 4-channel array of chip-scale atomic magnetometers in a flexible flying-lead configuration. These microfabricated, uncooled sensors with volumes below 1 cm3 demonstrate sensitivities around 100 fT/Hz1/2 and bandwidths of several hundred Hertz. Performance limits are discussed, as the design is easily scalable to different sensor sizes and large arrays. Initial measurements of MCG, MEG, and MRX are cross-validated with SQUID measurements.
