Miniaturizing coil system for uniform magnetic field in atom spin gyroscope by using natural selection algorithm

Year: 2025

Type: article

Abstract: This study explores the miniaturizing coil systems to generate uniform magnetic fields for Atom Spin Gyroscopes (ASGs), which is critical for improving the angular random walk of rotation sensors. Utilizing a natural selection algorithm, we optimize coil configurations to generate uniform magnetic fields within miniaturized cylindrical magnetic shielding. Experimental validation was conducted using a flexible printed circuit board-based coil system, demonstrating effective generation of spatially uniform magnetic fields. Results indicate that the magnetic field gradient generated by the coil system is 39.92 ± 2.36 nT/mm/A inside a cylindrical shield of 16 mm radius as measured by longitudinal (T1) and transverse (T2) spin relaxation times in an Rb and a Xe gas filled atomic cell. This approach paves the way for compact and high-performance ASG systems.
