5. The EPT development status
The (high flux) EPT prototype is being finalized and will be tested in november 2005.
This test will be followed by that of silicon sensors ( and half EPT) in january 2006.

6. Flight opportunity
The EPT schedule is drawn to fit into the development plan of the Environmental Explorer mission (NRL project)
The consortium is also interested in acquiring data on board Alphasat

7. The EPT development team
The EPT development was initiated in 1997 by Prof. Gh. Grégoire and Dr. M. Cyamukungu. The development of the DAM’s was supported by the Nuclear Physics Institute and the hardware for the prototype under construction was funded by the Belgian Institute for Space Aeronomy.
The construction of an Engineering Qualification Model is undertaken by an international team including skills from:
CSRCSR BelgiumBelgium
BISABISA BelgiumBelgium
Aboa Space Research OyAboa Space Research Oy FinlandFinland
ONERA/CNESONERA/CNES FranceFrance
With collaboration from NRL (USA) and Aerospace Corporation (USA)

The Energetic Particle Telescope (EPT) can be configured to measure particle fluxes in several radiation environment conditions.
Its main features are:
outstanding particle discrimination capability
high data acquisition rates due to digital operation mode
almost no background counting
extended energy range covered by a single instrument
digital reliability and built-in redundancy
