OPTICALLY PUMPED NUCLEAR MAGNETOMETER
A continuous recording total earth's field magnetometer is demonstrated that utilizes optical pumping in He/sup 3/ and the resultant polarization of the nuclear spins. The device operates as a self-oscillator at the Larmor frequency of the ground state atoms. The osciliator has a Q of 10/sup 4/ in a 0.5-G field. The sensitivity of the instrument to fluctuations in the magnetic field is presently several microgauss. The characteristics and operating principles of the instrument are described. The application of the device to the measurement of the absolute value of the total external magnetic field is discussed. (auth)
