Abstract
THE GOAL OF PHASE I IS DEVELOPMENT OF AN ADVANCED OPTICALLY PUMPED HELIUM MAGNETOMETER CONCEPT. THIS INSTRUMENT WILL MEASURE MAGNETIC FIELDS IN THE 1 TO 10-8 GAUSS RANGE WITH ORDER OF MAGNITUDE IMPROVEMENTS IN SENSITIVITY AND ABSOLUTE ACCURACY OVER EXISTING MAGNETOMETERS. OPTICALLY PUMPED HELIUM ISOTOPES CAN BE OPTICALLY PUMPED AND USED AS MAGNETOMETERS IN THE FOLLOWING THREE MODES: (1) VECTOR MODE (PARAMETER RESONANCE), (2) SCALAR MODE (MAGNETIC RESONANCE),AND (3) FREE PRECESSION MODE. SINGLE LINE PUMPING TO ACHIEVE IMPROVED SENSITIVITY AND ACCURACY WILL BE THEORETICALLY INVESTIGATED FOR EACH MODE. LASER DIODE SOURCES WILL BE SOUGHT AND, IF CURRENTLY AVAILABLE, EVALUATED FOR OPTICAL PUMPING AT 1.083 MICRON. AMAGNETOMETER CONCEPT WILL BE DEVELOPED WHICH IDENTIFIES THE OPTIMUM COMBINATION OF MODES AND PUMPING SOURCE FOR SPACE AND GEOPHYSICAL APPLICATIONS.
