The Energization and Radiation in Geospace (ERG) project will explore how relativistic electrons in the radiation belts are generated during space storms. ``High energy particle (electron)'' instrument (HEP-e) on board ERG satellite will measures 3-D distribution of high energy electron between 70 keV and 2 MeV. In high resolution mode, HEP-e measures the energy and incident direction of each electron with time resolution of 2 μsec.
The detection parts of HEP-e are six pinhole cameras which consist of mechanical collimators, silicon semiconductor detectors and readout ASICs. Three camera measure electrons with energy of 70 keV - 1 MeV and other three with energy of 700 keV - 2 MeV.
The flight model of HEP-e is under manufacture and the verification tests before integration are ongoing. In this presentation we introduce HEP-e instrument and report results of the step-by-step verification tests of each component before final assembly.
