两种型号光泵磁力仪绝对精度对比分析
Comparative analysis of absolute accuracy between two optical pump magnetometers
摘要
Abstract
Alkali metal optical pump magnetometers(OPMs)have been widely used in magnetic detection,previous studies primarily focused on the sensitivity of alkali metal OPMs.This paper emphasizes the comparative analysis on absolute accuracy of two alkali met-al OPMs:CS-3 cesium OPM from SCINTREX and GSMP-35 potassium OPM from GEM.Through analyzing the quantum properties of potassium and cesium atoms,it shows that potassium atoms exhibit larger and non-overlapping spacings between Zeeman resonance peaks under Earth's magnetic field;whereas cesium atoms,due to their broad ground-state energy levels,produce closely spaced Zee-man peaks with overlapping resonance signals,leading to ambiguity.The results of further comparative testing of the performance of two OPMs through experiments show that the absolute accuracy of potassium OPMs is much higher than that of cesium OPMs.Therefore,the localization of high-precision potassium OPMs has practical significance.关键词
