Total and Partial Fragmentation Cross-Section of 500 MeV/nucleon Carbon Ions on Different Target Materials

By using an experimental setup based on thin and thick double-sided microstrip silicon detectors, it has been possible to identify the fragmentation products due to the interaction of very high energy primary ions on different targets. Here we report total and partial cross-sections measured at GSI (Gesellschaft fur Schwerionenforschung), Darmstadt, for 500 MeV/n energy $^{12}C$ beam incident on water (in flasks), polyethylene, lucite, silicon carbide, graphite, aluminium, copper, iron, tin, tantalum and lead targets. The results are compared to the predictions of GEANT4 (v4.9.4) and FLUKA (v11.2) Monte Carlo simulation programs.Comment: 10pages, 13figures, 4table

Electro Static Discharge Testing on Meteosat 3

The electrostatic discharge testing on Photovoltaic Assemblies has been thoroughly investigated and performed during the last decade to ensure durability of solar arrays, especially in cases of high power satellites. Leonardo Company together with Aerospazio Tecnologie performed the test for the first time in the framework of Meteosat Third Generation (MTG, a Geostationary satellite of 2.5kW, mounting 3G solar cells) with two goals: the first was to qualify MTG PVA technology against possible ESD occurrences during mission and the second was to characterize the PVA design limits against self-sustained arcs. This paper illustrates the ESD analysis, the test set up preparation and the test results obtained in the framework of MTG ESD test campaign
