Investigation of an Exploratory Development Model of the 3HE Free Precession Gradiometer.

Abstract

This report describes the results of an investigation of an exploratory development model (XDM) of the 3He free precession gradiometer. The gradiometer is intended for use in a mine application. The investigation included the construction and evaluation of the XDM 3He gradiometer, an experiment to determine the effect of sensor orientation, an experiment to assess the effect of magnetic gradients on the magnetometer operation, and a detection test in which a magnet of known strength was carried on a straight line path past the gradiometer.
