Chip-Scale Combinatorial Atomic Navigator (C-SCAN) Low Drift Nuclear Spin Gyroscope
Abstract
We developed a (3)He(-129)Xe nuclear spin gyroscope probed by (87)Rb atoms. We batch fabricated gyroscope cells with a yield exceeding 85percent and achieved (129)Xe T2 time of 300 sec and (3)He T2 time of 3.9 hours in a 2 mm cell. We developed techniques to supress (87)Rb spin-exchange relaxation, (129)Xe back-polarization, and (3)He dipolar magnetic field. In a 10 mm cell we achieved Angle Random Walk (AFR) of 0.025 deg/hour(1/2), bias drift of less than 0.01 deg/hour, and absolute bias of less than 2.5 deg/hour without calibration. In a 2mm diameter anodically bonded cell we achieved ARW of 0.4 deg/hour(1/2). In a 1.6 cm3 physics package with the cell, heaters, and VCSEL lasers we demonstrated operation with an ARW of 8 deg/hour(1/2).
