Battlefield Applications for the Polatomic 2000 Magnetometer/Gradiometer

Abstract

This paper describes proposed battlefield applications for the POLATOMIC 2000 (P-2000), an optically pumped He(4) scalar magnetometer/gradiometer. A major innovation in the P-2000 helium magnetometer is the introduction of a laser pump source to replace the conventional RF discharge helium lamp used in the Navy AN/ASQ-81/208 MAD Set for airborne submarine detection. The P-2000 scalar magnetometer developed at Polatomic under sponsorship from ONRINAVAIR achieves a sensitivity improvement of a factor of 25 to 30 over the AN/ASQ-81/208. Results are discussed for Polatomic 2000 magnetometers operated on the Earth's surface as short baseline gradiometers demonstrating a magnetometer sensitivity approaching 0.1 pTrms/ square Hz for detecting small signals in the frequency band from 0.01 Hz to 120 Hz.
