Abstract
Abstract
The proton sensor is an important part of the proton magnetometer, which is mainly responsible for generating a polarizing magnetic field and receiving induced signals. This paper presents the design scheme of the proton sensor, including the selection of the internal coil structure of the sensor, the selection of the internal solution, and the design of the sensor shielding layer. Then introduces the proton sensor of the Canadian GSM-19T proton magnetometer, which is one of the world’s leading proton magnetometers. And the performance of the two sensors is compared and analyzed by designing sensor performance test experiment. The experimental results show that the initial amplitude of the test signal of the proton sensor is 2.2V, and the signal decay time constant is 0.86s, the performance is similar to that of the Canadian proton sensor.
