A new scalar magnetometer design enables measurement of magnetic fields with sensitivity down to 10 fT/Hz^(1/2), more than ten times better than existing devices. The Phase I effort will focus on bringing this recently proven technology into the field in a compact, robust, low-power implementation.

Twinleaf proposes to build, test and deliver a pair of scalar atomic magnetometers that exceed the performance of existing sensors while also being dramatically smaller and lighter weight. The Twinleaf scalar magnetometer has projected sensitivity better than 100 fT Hz^(-1/2) in a sensor package… More

The atomic spin gyroscope presented in this proposal is based on a new, very sensitive alkali-metal-noble-gas co-magnetometer sensor. Atomic spin is an ideal method for measuring orientation and rotation because vibrations and distortions of the sensor do not fundamentally change the orientation of… More

The atomic co-magnetometer gyroscope uses polarized nuclear spin to provide the highest demonstrated rotation sensitivity in a package significantly smaller than the best commercial fiber optic gyroscopes. The Twinleaf gyroscope moves beyond existing designs by using of neon-21 in place of helium-3,… More

Modern atomic magnetometer technology is poised to deliver total magnetic field measurements in a sensor that is dramatically less expensive, smaller, and lower-power relative to currently-available sensor systems. Using a combination of technologies that have emerged recently, we propose to develop… More

Co-magneometer atomic spin gyroscopes are rapidly progressing towards very high levels of sensitivity. The proposed work focuses on the engineering necessary to fully utilize the fundamental sensitivity of these sensors. In particular, we propose to develop a new probe beam optical system that… More
