G-882

The G−882 magnetometer employs an optically pumped Cesium-vapor atomic resonance system that functions as the frequency control element in an oscillator circuit. The frequency of the magnetometer’s electrical oscillator is known as the Larmor frequency.We measure those variations and send them to a computer for display and recording.
