| Zusammenfassung |
We present the first electron time-of-flight
measurements obtained with the Electron Drift Instrument (EDI) on Equator-S.
These measurements are made possible by amplitude-modulation and coding of the
emitted electron beams and correlation with the signal from the returning
electrons. The purpose of the time-of-flight measurements is twofold. First,
they provide the drift velocity, and thus the electric field, when the distance
the electrons drift in a gyro period becomes sufficiently large. Second, they
provide the gyro time of the electrons emitted by the instrument, and thus the
magnitude of the ambient magnetic field, allowing in-flight calibration of the
flux-gate magnetometer with high precision. Results of both applications are
discussed.
