Magnetometer (MAG)
GSFC

The magnetometer system is a simplified version of the magnetometers flown on Mars Global Surveyor and Lunar Prospector. It is a tri-axial flux gate design that will be mounted on the STEREO ~4m boom just inboard of the SWEA and STE instruments. The flux gate sensors use a ring core geometry, with magnetic cores consisting of molybdenum alloy. The units are compact, low power, and ultra-stable. To optimize sensitivity at the low field values to be found in interplanetary space, the magnetometer dynamic range is divided into 8 ranges that are automatically switched whenever the field being measured exceeds a predetermined level. The maximum range is sufficiently large to allow IMPACT MAG magnetic field measurements during the commissioning phase Earth orbits.
