| Zusammenfassung |
| LFEW is a low frequency electromagnetic wave detector mounted on TC-2, which
can measure the magnetic fluctuation of low frequency electromagnetic waves.
The frequency range is 8 Hz to 10 kHz. LFEW comprises a boom-mounted,
three-axis search coil magnetometer, a preamplifier and an electronics box
that houses a Digital Spectrum Analyzer. LFEW was calibrated at
Chambon-la-Forêt in France. The ground calibration results show that the
performance of LFEW is similar to that of STAFF on TC-1. The first results
of LFEW show that it works normally on board, and that the AC magnetic
interference of the satellite platform is very small. In the plasmasphere,
LFEW observed the ion cyclotron waves. During the geomagnetic storm on
8 November 2004, LFEW observed a wave burst associated with the oxygen ion cyclotron
waves. This observation shows that during geomagnetic storms, the oxygen
ions are very active in the inner magnetosphere. Outside the plasmasphere,
LFEW observed the chorus on 3 November 2004. LFEW also observed the
plasmaspheric hiss and mid-latitude hiss both in the Southern Hemisphere and
Northern Hemisphere on 8 November 2004. The hiss in the Southern Hemisphere may
be the reflected waves of the hiss in the Northern Hemisphere. |
