In the this paper, we report the results of modeling and simulation studies in which the radiation transport code FLUKA (FLUktuierende KAskade) is used to determine the changes in total ionizing dose (TID) and single-event effect (SEE) environments behind aluminum, polyethylene, carbon, and titanium shielding masses when the assumed form (i.e., Ban...

During the solar flares protons and heavier ions are accelerated up to GeV energies. Accelerated ions can escape the Sun and be registered directly on spacecraft or penetrate into the solar atmosphere and then produce gamma-ray lines as the result of nuclear reactions. Previous studies revealed very poor correlation between fluxes of interplanetary...

... In 2010, ground level enhancements to recent solar particle events were studied. FLUKA was used to predict in-space upset rates from the four recent SPEs modified with high-energy tails [276] . Estimates of the SEE rate were computed for three different spacecraft, flying at geosynchronous orbit or beyond, for which SPE SEE rates have been measured in-flight. ...
... The FLUKA-based calculations that account for shielding mass effects agree well with on-orbit data. A generalized, concentric spherical shell 3D spacecraft mass model was used in all the FLUKA-based SEU rate estimates to allow a computationally efficient inclusion of 3D (shielding mass distribution function) physical effects on space radiation transport without the computational burden that results from attempting simulation of each specific spacecraft shielding mass distribution function [276], [278] . Conventional methods of integrating the product of the environment with the geometry and part Weibull functions were used. ...
This anthology contains contributions from eleven different groups, each developing and/or applying Monte Carlo-based radiation transport tools to simulate a variety of effects that result from energy transferred to a semiconductor material by a single particle event. The topics span from basic mechanisms for single-particle induced failures to applied tasks like developing websites to predict on-orbit single event failure rates using Monte Carlo radiation transport tools.
