Extensive air shower modeling Flight altitude Geant4 MCNPX Monte Carlo method simulation South Atlantic Magnetic Anomaly |

Abstract |
Modeling cosmic-ray-induced particle fluxes in the atmosphere is very important for developing many applications in aeronautics, space weather and on ground experimental arrangements. There is a lack of measurements and modeling at flight altitude and on ground in the South Atlantic Magnetic Anomaly. In this work we have developed an application based on the Geant4 toolkit called gPartAt that is aimed at the analysis of extensive air shower particle spectra. Another application has been developed using the MCNPX code with the same approach in order to evaluate the models and nuclear data libraries used in each application. Moreover, measurements were performed to determine the ambient dose equivalent rate of neutrons at flight altitude in different regions and dates in the Brazilian airspace; these results were also compared with the simulations. The results from simulations of the neutron spectra at ground level were also compared to data from a neutron spectrometer in operation since February 2015 at the Pico dos Dias Observatory in Brazil, at 1864m above sea level, as part of a collaboration between the Institute for Advanced Studies (IEAv) and the French Aerospace Lab (ONERA). This measuring station is being operated with support from the National Astrophysics Laboratory (LNA). The modeling approaches were also compared to the AtmoRad computational platform, QARM, EXPACS codes and with measurements of the neutron spectrum taken in 2009 at the Pico dos Dias Observatory. |

Abstract |
This study analyzed the impact of galactic and solar cosmic rays on ambient dose equivalent during airline travel. A high statistic of flights are considered, which is representative of European international air traffic. Flight paths are based on the Eurocontrol Demand Data Repository and consider realistic flight plans with and without regulations or updated with radar data from the Central Flow Management Unit. Ambient dose equivalent during flights was investigated during quiet solar periods and extreme solar flare events. Thus, the statistical analyses presented here take into account route characteristics (departure, arrival, continent, etc.) and space weather conditions. The findings of this work show the important influence of flight path, particularly the latitude, which drives the cutoff rigidity variations. Moreover, dose values vary drastically during ground level enhancement events, with the route path (latitude, longitude and altitude) and the phasing of the solar event. This study highlights the importance of monitoring these solar events and developing a physical approach to obtain reliable assessment of ambient dose equivalents. |

Abstract |
In this paper the impact of the muon radial ionization profile on Single-Event Upset (SEU) sensitivity for nanoscale technologies is investigated with simulations and experimental measurements. The physical model used in the simulation framework is compared with experimental measurements of the charge deposit induced by atmospheric particles on a CCD pixel array. This scientific instrument is used to monitor the atmospheric muons, and allows to investigate the charge deposition induced by muon of micrometric sensitive volumes (i.e. the CCD pixel). Atmospheric and underground sites are considered for monitoring pixel-charge events and the combined analysis of the data is used to discriminate muons from other particles. 3D descriptions of muon tracks were simulated with radiation transport code Geant4, and coupled with Single Event Effect (SEE) simulation based on multi-physics approaches (MUSCA SEP3) to investigate the SEU cross-section and Soft Error Rate (SER) trends as function of technological downscaling. SER trends are analyzed for bulk technologies, from 65 to 14 nm integration nodes, in both ground and avionic environments. Results show that for technologies whose characteristic lengths are greater than 50 nm, it is not necessary to consider radial energy deposit structure of muon in SEE assessment. At ground, downscaling of the technological node induces an increase in the SEU susceptibility to cosmic ray showers, mainly because of muons. For nanoscale devices operating at avionic altitude, the muon contribution to the SER is very weak in comparison of the proton and neutron contributions. |
