abstract = {The 3DEES is conceived as a compact and modular science-class spectrometer allowing angle resolved high
electron energy coverage (0.1 – 10 MeV) using a few sensors. Its baseline set-up provides capabilities to
measure angular distribution of electrons and protons at 12 angles spanning over 180° in two planes. The
3DEES also allows measurements of proton fluxes (4-50 MeV), while performing absolute electron-proton
discrimination for protons up to 200 MeV.
The 3DEES is built within a consortium including QinetiQ Space, the Belgian Institute for Space Aeronomy
(BIRA/IASB) and UCLouvain. A first technology demonstration model is foreseen to fly on-board PROBA-3,
actually programmed to be launched in 2022 into a highly elliptical orbit: 60 530 km apogee, 600 km perigee,
59° inclination, 19.7 hours orbital period. With these orbital parameters, the satellite will cover parts of the
inner belt, outer belt and mostly the boarder of the magnetosphere. Hence, the ultimate objectives of the
3DEES mission are to give an accurate picture of the high-energy electron population in the magnetosphere
for scientific studies of their acceleration and loss processes and to deliver Space Weather data for now- and
forecasting activities. It completes the PROBA-V/EPT (Energetic Particle Telescope) mission with additional
data at high altitude.
The talk will give a general presentation of the instrument wherein the main features of the 3DEES will be
revisited, focusing on the design, building and calibration of the prototype sensor stack that includes four 1.5
mm thick sensors and adjacent electronics and which particularity is that it is moulded in order to achieve
miniaturization and mechanical robustness. Finally, the planned accommodation of 3DEES on-board PROBA-

along the track of the affected cells is discussed. The results of the
experiments with different beams (both directly and indirectly
ionizing) are illustrated. A set of Monte Carlo simulations is
also presented, to study sensitive volumes on 3-D NAND floating
gate cells and explore the possibility of distinguishing the effects
generated by ionizing particles with different features, such as
LET and angle of incidence. |

abstract = {ATHENA is the second large mission in ESA Cosmic Vision 2015-2025, with a launch foreseen in
2028 towards the L2 orbit. The mission addresses the science theme “The Hot and Energetic
Universe”, by coupling a high-performance X-ray Telescope with two complementary focal-plane
instruments. One of these, the X-ray Integral Field Unit (X-IFU) is a TES based kilo-pixel array,
providing spatially resolved high-resolution spectroscopy (2.5 eV at 6 keV) over a 5 arcmin FoV.
The background for this kind of detectors accounts for several components: the diffuse Cosmic Xray Background, the low energy particles (< ~100 keV) focalized by the mirrors and reaching the
detector from inside the field of view, and the high energy particles (> ~100 MeV) crossing the
spacecraft and reaching the focal plane from every direction. In particular, these high energy
particles lose energy in the materials they cross, creating secondaries along their path that can induce
an additional background component.
Each one of these components is under study of a team dedicated to the background issues regarding
the X-IFU, with the aim to reduce their impact on the instrumental performances. This task is
particularly challenging, given the lack of data on the background of X-ray detectors in L2, the
uncertainties on the particle environment to be expected in such orbit, and the reliability of the
models used in the Monte Carlo background computations. As a consequence, the activities
addressed by the group range from the reanalysis of the data of previous missions like XMMNewton, to the characterization of the L2 environment by data analysis of the particle monitors
onboard of satellites present in the Earth magnetotail, to the characterization of solar events and their
occurrence, and to the validation of the physical models involved in the Monte Carlo simulations.
All these activities will allow to develop a set of reliable simulations to predict, analyze and find
effective solutions to reduce the particle background experienced by the X-IFU, ultimately satisfying
the scientific requirement that enables the science of ATHENA.
While the activities are still ongoing, we present here some preliminary results already obtained by
the group. The L2 environment characterization activities, and the analysis and validation of the
