Geant4 and its validation

Nuclear Physics B - Proceedings Supplements, 2006
Geant 4 is an object-oriented toolkit for simulating the passage of particles through matter. At the very heart of Geant 4 there is a wide set of complementary, and sometimes alternative, physics models which describe the basic interaction of particles with matter.

PIXE Simulation With Geant4

IEEE Transactions on Nuclear Science, 2009
Particle induced X-ray emission (PIXE) is an important physical effect that is not yet adequately modelled in Geant4. This paper provides a critical analysis of the problem domain associated with PIXE simulation; it evaluates the conceptual approach, design and implementations of PIXE modelling so far available in Geant4, and describes a set of ...

GEANT4-MT : bringing multi-threading into GEANT4 production

SNA + MC 2013 - Joint International Conference on Supercomputing in Nuclear Applications + Monte Carlo, 2014
GEANT4-MT is the multi-threaded version of the GEANT4 particle transport code.(1, 2) The key goals for the design of GEANT4-MT have been a) the need to reduce the memory footprint of the multi-threaded application compared to the use of separate jobs and processes; b) to create an easy migration of the existing applications; and c) to use efficiently ...
