GSM-19 high precision Overhauser magnetometer@GSM-19%

A, application field:

Proton precession magnetometer (Overhauser) is a high precision instrument that is better than the proton precession magnetometer and optical pumpmagnetometer. It has a series of unique advantages, and has become a high precision magnetic observationsystem standard, it is successfully applied to the:

- high precision magnetic survey and prospecting

- magnetic basement and structure detection

- precursor and volcano precursory observation

Engineering and environmental exploration

Pipeline and underground explosive detection

Archaeology

Two, proton precession magnetometer principle: with theunpaired electron special liquid and hydrogen atomscombine and placed in a radio frequency (RF) magnetic field is polarized, with a polarized unpaired electron willtransfer its polarization information to the hydrogen atom,and thus a precession signal. This change in precessionsignal to total magnetic intensity is very high sensitivity, it is especially suitable for high precision magnetic surveygeological survey. Proton precession magnetometer(Overhauser) produce radio frequency (RF) magnetic field energy required is small, and the RF magnetic fieldfrequency in the precession frequency, so as to maximize the elimination of noise. In addition, the poling processand precession signal observation can be carried out at the same time, thereby increasing the observation efficiency. Proton precession magnetometer(Overhauser) digital collection quality, working efficiency and high stability effectively together.
