The Energetic Particle Detector (EPD) is an instrument suite comprising different sensors that have been designed
to measure the spectra, composition, time variations, and directional distributions ofenergetic particles.
These measurements will be performed over a partly overlapping energy range encompassing a few keV to
450 MeV/n, with sufficient time, energy, angular, and mass resolution to achieve the mission science goals.
The EPD consists of the following units :
* High Energy Telescope (HET).

    HET measures electrons, protons and heavy ions and covers 
    the upper energy end of the EPD range. There two HET units, each consisting of a double-sided telescope and an 
    electronics box which is shared with EPT. Consequently it provides measurements in 4 distinct fields 
    of view (the same as EPT). Each telescope contains 2 solid state detectors (A and B) for each direction and a shared BGO 
    scintillator (C). Measuring the characteristics of the energy deposition in the different detectors, HET is able to 
    identify particle species in a wide energy range.
