Abstract
In a magnetic field measuring device, conveyed by a carrier vehicle and released from this vehicle in order to be put into action, the excitation means and the measuring means of a nuclear magnetic resonance helium magnetometer are separated. These measuring means are fixed to a body which includes devices for the transmission and exploitation of the measurements given by the measuring means, and this set is released after the exzcitation is completed while the excitation means remain fixed in the carrier vehicle. This makes it possible to fabricate smaller and lighter magnetic localizing buoys.
Claims11
A method for the measurement of the magnetic field by means of a helium-type releasable magnetometer, comprising excitation means and measuring means, comprising a helium cell, wherein this helium cell is excited, the excitation means and the measuring means are separated, these measuring means are released to make them go to the place where the measurement has to be made, and a measurement is made of the precession of the helium atoms under the effect of the magnetic field to be measured.
Helium type releasable magnetometer comprising excitation means and measuring means capable of being separated from the excitation means, wherein the excitation means are connected to a carrier vehicle and the measuring means can be released from this vehicle.
