Abstract

The Japanese Akebono (EXOS-D) satellite was successfully put into a semipolar, elliptical orbit in order to study particle acceleration processes in the auroral magnetosphere. The onboard LEP (low energy particle) instrument makes three distinct types of charged particle observations: 1) energy and pitch-angle distributions of auroral electrons and ions, 2) mass per charge analysis of positive ions, and 3) onboard detection of particle flux modulations in the HF and VLF ranges. This report describes the LEP instrumentation and configuration, emphasis is placed on dayside phenomena, including the polar cusp. -from Authors
