A QUASI ABSOLUTE OPTICALLY PUMPED MAGNETOMETER FOR THE PERMANENT RECORDING OF THE EARTH MAGNETIC FIELD VECTOR

Eberhard Pulz – Karl-Heinz Jäckel – Oliver Bronkalla

   At the Niemegk observatory, two different types of absolute measuring magnetometers were developed and built. One of them should replace the D/I-flux; it performs absolute component measurements at defined times (GAUSS). In this paper we describe an instrument which delivers every second a complete set of the Earth magnetic components in near absolute quality. It consists o a very fast Cs, Cs-He tandem magnetometer and a two dimensional coil-system and will be equiped with an optical system for the direction definition.

Keywords: recording of one-second mean values of the Earth's magnetic field components in near absolute quality
