GRAS (Geant4 Radiation Analysis for Space)

GRAS is a Geant4-based tool enabling common radiation analyses types (TID, TNID, fluence, SEE, path length, charge deposit, dose equivalent, equivalent dose, radiation detection response, imaging sensor background,...) in generic 3D geometry models.

GRAS draws from the strength of Geant4 in particle-matter interaction physics modelling and geometry description, and augments it with ease of use in defining typical use cases for radiation analyses, from dosimetry to single event effects and detector response.

The main GRAS SW design requirements are flexibility and modularity of the application. Thanks to flexibility GRAS can be used for obtaining a variety of simulation output types for generic (GDML or C++) 3D geometry models, avoiding the creation of a new tailored C++ Geant4-based application for every new project. Thanks to a modular design, the GRAS analysis type capabilities can be easily extended by advanced users.
