一种射频-脉冲激发式动态核极化磁场传感器
A Kind of RF-Pulse Excitation DNP Magnetic Sensor
摘要
Abstract
The paper introduces a kind of RF-pulse excitation Dynamic Nuclear Polarization ( DNP ) effect proton magnetometer. The electron-proton double resonance phenomenon and the dynamic nuclear polarization characteristics of nitroxide radicals were analyzed,the structure of the RF-pulse excitation DNP effect proton magne-tometer based on nitroxide radicals and the working processing of magnetometer were given,and the magnetometer prototype was implemented by designing of each functional modules. The experiment results show that the magnetic field of the magnetic sensor prototype have high sensitivity;The accuracy test results show that the measurement un-certainty is about 0. 3 nT from 20000 nT to 100000 nT.关键词
