GGS: a Generic Geant4 Simulation package for small- and medium-sized particle detection experiments

Abstract: The Generic Geant4 Simulation (GGS) is a package designed to speed-up the realization and deployment of Monte Carlo simulation software based on Geant4, for small- and medium-sized high-energy experiments. For many common use cases, the task of setting up a full-featured simulation of the detector is reduced to the definition of the detector geometry, by providing generic and reusable implementations of the mandatory Geant4 user classes (particle generation, scoring, output etc.). Extensibility is provided by a simple plugin system that allows replacing of the generic implementations distributed with GGS with custom ones. These features make it especially suitable for cases where limited manpower, like during preliminary detector design studies, can severely limit the scope of an R&D program.
