Abstract

The Energetic Particle Telescope (EPT) is a new compact and modular ionizing particle spectrometer that was launched on 7 May 2013 to a LEO polar orbit at an altitude of 820 km onboard the ESA satellite PROBA-V. First results show electron, proton and helium ion fluxes in the South Atlantic Anomaly (SAA) and at high latitudes, with high flux increases during SEP (Solar Energetic Particles) events and geomagnetic storms. These observations help to improve the understanding of generation and loss processes associated to the Van Allen radiation belts.

Funding

The development of the EPT instrument was realized with the support of the Belspo and of the European Space Agency (ESA) (contracts 20294/06/NL/JD (Phase A/B) and 22582/09/NL/AT (Phase C/D)). The design of the EPT instrument and its integration on the PROBA-V satellite results from a fruitful Consortium between the Université Catholique de Louvain, the Belgian Institute for Space Aeronomy and QinetiQ Space. The B.USOC and the control center in Redu provide data transmission and storage. The authors thank all the scientists who temporarily participated to the development of the EPT instrument and its integration on PROBA-V satellite, as well as the administrative teams of the different institutes. The CSR team also thanks Belspo for supporting the “PROBA-V/EPT – Data Exploitation” project via the PRODEX program under ESA contract C4000107617) and for the PRODEX-7 (N° 90098+ CCN-1/C 90098). They also thank G. Tabordon, L. Kruijfthooft, C. Thielens, B. de Callatay and the radioprotection and cyclotron teams.
