Noise Measurements and Current Driver Improvements for an Atom Interferometer Gyroscope

Abstract

We present noise measurements for our Bragg interferometer gyroscope in a time-orbiting potential trap. We obtain an Allan deviation plot that demonstrates averaging improvement as 1/T up to integration times T of 2.5 h. However, it exhibits an unexpected short term noise level of approximately 9 rad/Hz. We attribute this primarily to real phase noise in the interferometer caused by fluctuations in the trap drive current. We have developed and constructed new high-bandwidth current amplifiers that we anticipate will improve performance.
