The Isotope Shift Suppression in NMR-based Balanced Quantum Rotation Sensor
https://doi.org/10.17285/0869-7035.0089
Abstract
Designing a compact balanced quantum rotation sensor (gyroscope) based on nuclear magnetic resonance in xenon is one of the most urgent and promising tasks in modern metrology. The ultimate accuracy of the sensor is mostly constrained by the isotope shift conditioned by the difference in relaxation rates of two xenon isotopes under spatially nonuniform spin-exchange pumping of nuclear magnetic moments. The proposed method for suppressing the isotope shift and its partial derivatives is based on creating the external magnetic field with nonlinear spatial gradient. The simulation results based on experimental data demonstrate that the method can be applied to small gas cells with higher spatial nonlinearity of pumping parameters.
