Design of JOM-5V Vector Overhauser Magnetometer
摘要
Abstract
Vector Overhauser magnetometer can measure magnetic inclination I and magnetic declination D on the basis of total field F,which is widely used in the field of geomagnetic science research area.To meet the demand of simultaneous measurement of F,I and D,JOM-5V vector Overhauser magnetometer is developed.The magnetometer adopts the sensors of the land JOM-5 series portable Overhauser magnetometer,and combines the Helmholtz coil and solenoid coil to form the main structure of the vector magnetometer,which is simpler than the structure of the vector magnetometer with spherical coils,and is easy to commercialize.The experimental results show that the sensitivity of JOM-5V vector Overhauser magnetometer can reach 0.016 8 nT at a measurement period of 5 s,and the sensitivities of magnetic inclination and magnetic declination are 0.011 5° and 0.013 8°,respectively.The results show that the JOM-5V vector Overhauser magnetometer is able to meet the measurement needs of F,I,D geomagnetic variables,which provides technical and equipment support for geomagnetic scientific research in China.关键词
