Proton upset rate simulation by a Monte Carlo method: importance of the elastic scattering mechanism
Publikováno v:
IEEE Transactions on Nuclear Science. 44:2243-2249
This paper describes the calculation of the proton upset cross section by a Monte Carlo method (SEUSIM code). The computation combines heavy ion experimental data and the results of modelling of the inelastic nuclear reaction (NUREAC code). We improv

Until now, the effects of the space environment on the electronics of European launchers had never been taken into account. The situation has changed entirely with the ARIANE 5 launcher, whose trajectory may go up to 3000 km. This presentation explai

This paper describes the results of a study carried out to measure the actual deformation of a Zerodur telescope mirror due to electron irradiation simulating the dose expected on a satellite in geostationary orbit (GEO). The purpose of the work was

Radiation hazard during previous manned space flights was not a critical problem as seen from monitoring on board MIR and the SHUTTLE. Future Martian and Lunar missions as well as flights on inclined or high altitude orbits around the Earth can be ex

This paper presents the doses levels expected in orbits in chart form, covering the range 300–800 km of altitude and 0–90° of inclination behind shieldings similar to the Hermes spacecraft and the EVA spacesuit matter distributions. These charts

The effects of radiation on spacecraft materials and electronic devices are directly related to the energy transferred by incident particles to the components (atoms, orbiting electrons and nuclei) of the matter encountered. Such events result in the

The authors present a method for predicting proton-induced single-event upset (SEU) rates in devices exposed to given proton fluxes, within a particular spacecraft shielding. The approach uses experimental heavy-ion cross-section data, combined with

The space environment is constituted by the outer parameters' which may have an influence on the acting and behaviour of spacecraft components. The principal are : pressure, temperature, density and composition, of upper atmosphere, electric and magn
