Atom spin gyroscope based on Rb-Xe vapor cell.

POSTER

Abstract

We present results of atom spin gyroscope (ASG) using dual species of noble gases. The vapor cell contain Rb, $^{\mathrm{129}}$Xe, $^{\mathrm{131}}$Xe, N$_{\mathrm{2}}$, and H$_{\mathrm{2}}$ gases. The magnetic field fluctuation can be reduced by using two Larmor frequencies of 118 Hz and 35 Hz, respectively. We apply parametric modulation of z-axis of magnetic field to extract the $^{\mathrm{129}}$Xe and $^{\mathrm{131}}$Xe signals. The transverse relaxation time of $^{\mathrm{129}}$Xe and $^{\mathrm{131}}$Xe are 70 s and 10 s, respectively. The Angular Random Walk (ARW) of the ASG is 0.98 deg/h$^{\mathrm{1/2}}$ and Bias instability is 5.46 deg/h. Further developments will be made by enriched Xe vapor cell.
