Geant4 [ref G1, ref G2] is a simulation toolkit written in C++ using Object-Oriented principles, and re-engineered from the Fortran-based Geant3. As of Geant 3.21, the Fortran code is officially no longer supported. Geant4 is developed and maintained by a world-wide collaboration including centers at CERN, SLAC, FNAL, KEK and others. The code is available without cost at http://geant4.cern.ch, ...

We introduce a new implementation of the Liège cascade INCL4.2 and of the evaporation/fission code ABLA v3 in Geant4. INCL treats the cascade of hadron, deuterium, tritium, and helium projectiles of energies up to 3 GeV, while ABLA, based on evaporation and fission, provides a treatment of the excited nucleus produced at the end of the cascade. Details of the implementation of INCL and ABLA in ...

The Geant4 Visualisation System is a multi-driver graphics system designed to serve the Geant4 Simulation Toolkit. It is aimed at the visualization of Geant4 data, primarily detector descriptions and simulated particle trajectories and hits. It can handle a variety of graphical technologies simultaneously and interchangeably, allowing the user to choose the visual representation most appropriat...

Geant4 is a toolkit for the simulation of the passage of particles through matter. It provides a comprehensive set of tools for geometry, tracking, detector response, run, event and track management, visualization and user interfaces. Geant4 also has an abundant set of physics models that handle the diverse interactions of particles with matter across a wide energy range. However, there are als...

GEANT4 is a toolkit for simulating the passage of particles though matter, which contains a complete range of functionality including tracking, geometry, physics models, and hits. In this article, an attempt to use GEANT4 Monte Carlo code to watch a double-gap Resistive Plate Chamber's (RPC) response to neutrons is presented. The simulation calculations of the double-gap RPC have been evaluated...

The need for proliferation-resistance, longer fuel cycles, higher burn up and improvedwaste form characteristics has led to a renewed worldwide interest in thorium-based fuels and fuel cycles. In this paper the GEANT4 Monte Carlo code has been used to simulate the Thorium-Uranium fuel cycle. The accelerator driven fertile to fissile conversion rates have been calculated for various geometries. ...

In the context of critical applications, such as shielding and radiation protection, ensuring the quality of simulation software they depend on is of utmost importance. The assessment of simulation software quality is important not only to determine its adoption in experimental applications, but also to guarantee reproducibility of outcome over time. In this study, we present initial results fr...

Introduction: Now day Ionizing radiation has found increasing applications in cancer treatment. However, in the treatment different kinds and size of tumors especially metastatic and small size tumors, conventional methods of external radiation therapy are not common. In radionuclide therapy, the use of monoclonal antibodies has made it possible to achieve maximum dose to small size tumor and m...
