Abstract

Electric field detectors (EFD) on the EXOS-D (Akebono) satellite measure the vector electric field by both the standard double probe technique (EFD-P) and the newly developed ion beam technique (EFD-B). This paper describes the instrumentation and preliminary observed results obtained by the EFD-P such as the Langmuir characteristics of the probe in the plasmasphere and the convection electric field in the auroral ionosphere. An intense electric field has been observed between the region 1 and 2 current on the morning side. Close to the mid-day meridian, fluctuating electric fields that are likely to be related in terms of a cusp/cleft structure were observed. -from Authors
