Cosima is the Geant4-based simulator of the medium-energy gamma-ray astronomy library MEGAlib. Within the MEGAlib framework, Cosima is designed to be a simple, fool-proof interface to Geant4 and to enable the simulation of most of the measurement scenarios encountered by X-ray and gamma-ray detectors in space and on Earth.

The scintillator has played a primary role as the ideal device for detection and measurement of particles radiation in modern physics. With development experimental physics, demand new improved scintillating materials several types applications kept increasing. High efficiency, fast scintillation good energy resolution are among most desired specifications to scintillator. Yet, variety scintill...

We are investigating different micro- and nano-structure approaches to neutron detection based on inorganic scintillators. Specifically, we have been assessing various converter-scintillator configurations through simulations experiments. One promising scintillator is ZnO due its relatively high light yield [1] , reasonable optical transparency in the visible region [2] low refractive index [3]...

A Geant4 hadronic process verification suite has been designed to test and optimize Geant4 hadronic models in the cascade energy range. It focuses on quantities relevant to the LHC radiation environment and spallation source targets. The general structure of the suite is presented, including the user interface, stages of verification, management of experimental data, event generation, and compa...

Opticks is an open source project that accelerates optical photon simulation by integrating NVIDIA GPU ray tracing, accessed via OptiX, with Geant4 toolkit based simulations. A single Turing architecture has been measured to provide speedup factors exceeding 1500 times threaded a full JUNO analytic geometry automatically translated from the geometry. Optical physics processes of scattering, abs...

The aim of this work was to study the influence of Geant4 parameters on dose distribution and computational time for simulations of carbon ion therapy. The study was done using Geant4 version 9.0. The dose distribution in water for incident monoenergetic carbon ion beams of 300 MeV/u were compared for different values of secondary particle production threshold and different step limits. Variati...
