Abstract

A single-event effect (SEE) simulation toolkit has been developed at CERN for the whole radiation effects community and released as an open-source code. It has been validated by comparing the simulated energy deposition of inelastic interactions, due to monoenergetic neutrons in the 1.2–17 MeV energy range, to the distribution measured experimentally by a silicon diode detector.

Highlights

  • Monte Carlo (MC) tools are extensively used in the domain of radiation effects on electronics [1], and more for high-energy accelerator applications

  • In the case of Single Event Effects (SEEs), this second type of simulations involves the scoring of the event-by-event energy deposition in micrometric volumes, representative of the SEE sensitive volumes (SVs)

  • Users can make use of NIST materials predefined by G4 [24], and can define any custom material used in electronic components via macro commands: elements with user-defined isotope abundances, compounds consisting of various elements (e.g. Si3N4), or even mixtures of different materials

Summary

INTRODUCTION

Monte Carlo (MC) tools are extensively used in the domain of radiation effects on electronics [1], and more for high-energy accelerator applications. The primary MC tool used so far for such simulations was FLUKA [10], developed and distributed by CERN, and which is the workhorse for calculations of the radiation environment around the accelerator. Another important contribution to the mixed-field overall SEE rate, in addition to those introduced above, comes from so-called intermediate energy neutrons, in the 0.2–20 MeV range [11]. Users can make use of NIST materials predefined by G4 [24], and can define any custom material used in electronic components via macro commands: elements with user-defined isotope abundances, compounds consisting of various elements (e.g. Si3N4), or even mixtures of different materials
