Query: Monte Carlo simulations of Gamma-ray space telescopes: a BoGEMMS
  multi-purpose application   After the development of a BoGEMMS (Bologna Geant4 Multi-Mission Simulator)
template for the back- ground study of X-ray telescopes, a new extension is
built for the simulation of a Gamma-ray space mission (e.g. AGILE, Fermi),
conceived to work as a common, multi-purpose framework for the present and
future electron tracking gamma-ray space telescopes. The Gamma-ray extension
involves the Geant4 mass model, the physics list and, more important, the
production and treatment of the simulation output. From the user point of view,
the simulation set-up follows a tree structure, with the main level being the
selection of the simulation framework (the general, X-ray or gamma-ray
application) and the secondary levels being the detailed configuration of the
geometry and the output format. The BoGEMMS application to Gamma-ray missions
has been used to evaluate the instrument performances of a new generation of
Gamma-ray tele- scopes (e.g. Gamma-Light), and a full simulation of the AGILE
mission is currently under construction, to scientifically validate and
calibrate the simulator with real in-space data sets. A complete description of
the BoGEMMS Gamma-ray framework is presented here, with an overview of the
achieved results for the potential application to present and future
experiments (e.g., GAMMA-400 and Gamma-Light). The evaluation of the photon
conversion efficiency to beta particle pairs and the comparison to tabulated
data allows the preliminary physical validation of the overall architecture.
The Gamma-ray module application for the study of the Gamma-Light instrument
performances is reported as reference test case.
