摘要:

我们描述了一个简单的原子磁力计的发展,使用$^{87}$ Rb蒸汽适用于地球磁场监测。磁力计是基于时域确定的瞬态进动频率的原子排列周围的测量领域。在实验室对地球磁场的测量中,证明了其灵敏度为1.5 nT/ $\sqrt{Hz}$。我们讨论了决定磁力计精度和准确度的不同参数,并预测灵敏度为30 pT/ $\sqrt{Hz}$

英文摘要:

We describe the development of a simple atomic magnetometer using $^{87}$Rb vapor suitable for Earth magnetic field monitoring. The magnetometer is based on time-domain determination of the transient precession frequency of the atomic alignment around the measured field. A sensitivity of 1.5 nT/$\sqrt{Hz}$ is demonstrated on the measurement of the Earth magnetic field in the laboratory. We discuss the different parameters determining the magnetometer precision and accuracy and predict a sensitivity of 30 pT/$\sqrt{Hz}$
