Mission Name: THEMIS-B (ARTEMIS-P1)The electric field instrument (EFI) consists of 4 spin-plane spherical sensors each on a 20 m deployable cable and 2 axial tubular sensors, each mounted on 5m-long stacer elements. The experiment was built by UCB to the heritage of S3-3, ISEE1, CRRES, and POLAR, and identical to the ones used on the CLUSTER satellites. Signal processing takes place in the IDPU, together with the SCM. Routine waveforms (at 32samples/s) or burst waveforms (at 128 - 8192 samples/s) are captured and processed just as for the SCM data. Spectral processing of the low frequency (<8 kHz) data occurs in the DSP in a fashion identical to the SCM. Individual probe calibration results in absolute DC measurement accuracy of 0.1 mV/m, i.e., <10% of the field value anticipated during fast flows. Inter-spacecraft calibration is preformed during quiet times.
