2.4.1 spase://CNES/Instrument/CDPP-AMDA/Helios2/MAG MAG Helios Magnetometers : E2, E3 2018-10-20T21:10:13Z E2 : The Förster probe experiment E2 is a three component-vector magnetometer. Its purpose is to continuously observe the interplanetary magnetic field in a frequency range up to 4 Hz. Thereby certain phenomena are to be analysed as a function of the distance from the sun e.g. the spiral structure and discontinuities. The measurement ranges are ± 100 nT and ± 400 nT. The resolution is ± 0.2 nT and ± 0.8 nT respectively. For accurate measurements of the zero offset of each sensor the component parallel to the spinaxis can be flipped by 90°. Depending on telemetry format and bitrate the digital data are fed into a time average computer or directly connected to telemetry. A shock identification-computer triggers the S/C core memory in case of discontinuities with variations of the ambient magnetic field magnitude. The Förster probe experiment E2 is a three-axe vector magnetometer. It is used for the continuous observation of the interplanetary magnetic field in a frequency range from 0 to 4 Hz. This will be investigated phenomena such as the spiral structure and discontinuities as a function of the distance from the Sun. The measuring ranges are ± 100 nT and ± 400 nT with a resolution of ± 0.2 nT or ± 0.8 nT. The component that is parallel to the axis of the spin, to perform precise zero point provisions of each sensor is rotated 90 degrees. Depending on format and bit rate digital data pass through an average computer or directly to the telemetry. A shock wave identification computer triggers the S/C core memory in the presence of discontinuities with magnetic field variations.
