Embodiment Construction

[0021] The principles and features of the present invention are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.

[0022] Such as figure 1 As shown, a probe of a proton magnetometer includes an electric field shield, two coils 3 and a solution with a hydrogen proton concentration greater than or equal to 100mol / L. The solution is poured into the electric field shield, and the two coils 3 are connected in series in opposite directions and soaked in solution; the two ends of the coil 3 are set outside the electric field shield.

[0023] Specifically, the electric field shield is composed of a cylinder body 1 and a cylinder cover 2 . The cylinder cover 2 is fastened on the opening end of the cylinder body 1, and a sealing ring 8 is arranged between the two to prevent leakage of the solution poured into the electric field shield. ...

Abstract

The invention relates to a probe of a proton magnetometer, which includes an electric field shield, two coils, and solution containing rich hydrogen protons. The solution is poured into the electric field shield. The two coils are reversely connected in series and immersed in the solution. The two ends of the coils are arranged outside the electric field shield. When the probe is used, the coils are powered on to generate a magnetic field, which can make the hydrogen protons in the solution arranged orderly in one direction. Then, the coils are powered off, and the hydrogen protons rotate in the direction of the terrestrial magnetic field. As the rotation frequency of the hydrogen protons is proportional to the intensity of the terrestrial magnetic field, the intensity of the terrestrial magnetic field can be measured by measuring the rotation frequency of the hydrogen protons.

Description

technical field [0001] The invention relates to the field of proton magnetism detection, in particular to a probe of a proton magnetometer. Background technique [0002] The proton magnetometer is a kind of geophysical weak magnetic measuring instrument, which can measure the total field strength of the geomagnetic field. It has the characteristics of simple structure, stable signal, high precision, good reliability, moderate price and easy to carry. It is widely used in energy exploration, space exploration, military field and scientific research field. [0003] In the high-precision magnetic prospecting work, the probe plays an important role as the signal sensor of the proton magnetometer. The probe needs to convert the very weak proton precession signal that can reflect the strength of the geomagnetic field into an electrical signal that can be accurately measured. The selection of polarized samples, anti-interference measures, and coil and structural design are three k...
