Abstract

The invention provides a probe structure based on a double-air-chamber optical pumping alkali metal atom gradient magnetometer. The probe structure comprises a double-air-chamber electric oven base, apumping light pipe mounting assembly, an electric oven assembly, a detection light pipe, a magnetometer probe shell assembly and a magnetometer probe upper cover plate assembly; two alkali metal airchambers are designed; after being installed and fixed, the two alkali metal air chambers are located in the same plane, debugging and building of the optical paths are facilitated, and the complexityof external equipment can be effectively reduced; Glass tail handles of the two air chambers are placed in open holes of a double-air-chamber installation adjusting stud to be fixed, the distance between the two air chambers can be changed by modifying the center distance between the two open holes of the double-air-chamber installation adjusting stud, the angle between the two air chambers can be changed by modifying the assembly tool, and the position and angle between the two air chambers can be conveniently changed. Therefore, different measurement requirements are met.

Description

technical field [0001] The invention relates to the technical field of quantum precision measuring instruments, in particular to a probe structure of an alkali metal atomic gradient magnetometer. Background technique [0002] With the development of quantum technology, various scientific instruments based on quantum effects are continuously and substantially breaking through the measurement limits of traditional instruments. As a quantum instrument that utilizes the atomic spin effect to achieve precise magnetic field measurement, the atomic magnetometer has unparalleled advantages in performance indicators compared to other types of magnetometers, and is an important part of the new generation of ultra-high sensitivity magnetometers. Direction of development. [0003] An atomic magnetometer is a quantum instrument that uses atomic spin effects to achieve precise magnetic field measurements. Most sensitive atomic magnetometers use alkali metal vapor near zero field to put a...
