Abstract

A NOVEL HIGH-PERFORMANCE HELIUM FREE PRECESSION (HFP) MAGNETOMETER IS USED IN GEOMAGNETIC FIELD MEASUREMENTS AND MAGNETIC GEOPHYSICAL EXPLORATION. RESEARCHERS ARE DEFINING A CONCEPT FOR A PORTABLE LASER-PUMPED HELIUM 3 MAGNETOMETER WHICH HAS SMALL SIZE , HIGH SENSITIVITY AND LOW POWER CONSUMPTION. THE KEY TECHNICAL COMPONENT IS A MINIATURE TUNABLE NEAR-INFRARED LASER PUMP SOURCE IN A HELIUM 4 SPACE MAGNETOMETER. THE LASER PUMPING LIGHT AND SENSOR READ-OUT IS CARRIED BY OPTICAL FIBER LINK BETWEEN THE SENSOR AND THE LASER/ELECTRONICS PACKAGE. THE FEASIBILITY OF THE LASER-PUMPED HELIUM 3 MAGNETOMETER AND THE LASER PUMP SOURCE FOR PUMPING HELIUM 3 IS BEING ASSESSED.
