Abstract

Abstract

En 中文
• An integrated polarization-heating probe is developed for Cs FID magnetometry. • A single helical coil provides vapor-cell heating and polarization. • Temporal decoupling suppresses coil-induced perturbations during FID readout. • The 18.5 × 17.5 × 36.5 mm probe consumes about 0.7 W. • The sensor achieves 15 pT/√Hz sensitivity with a maximum residual of 8.980 nT after correction.
