It is proposed to use 14 MeV neutrons tagged by the associated particle neutron time-of-flight technique (APnTOF) to identify the fillers of unexploded ordnances (UXO) by characterizing their carbon, nitrogen and oxygen contents. To facilitate the design and construction of a prototype system, a preliminary simulation model was developed, using the Geant4 toolkit. This work established the tool...

The G4beamline program [1] is a useful and steadily improving tool to quickly and easily model beamlines and experimental equipment without user programming. Unlike most accelerator physics codes, it easily handles a wide range of materials and fields, being particularly well suited for the study of muon and neutrino facilities. As it is based on the Geant4 toolkit [2], G4beamline includes most...

This paper presents the simulation of the GLAST high energy gamma-ray telescope. The simulation package, written in C++, is based on the Geant4 toolkit, and it is integrated into a general framework used to process events. A detailed simulation of the electronic signals inside Silicon detectors has been provided and it is used for the particle tracking, which is handled by a dedicated software....

The Fermi LAT collaboration has built up a detailed Monte Carlo simulation to characterize the instrument response and tune its performance. The simulation code is built around the widely used GEANT4 toolkit and was carefully validated against beam test and flight data. This poster shows how the full LAT simulation is used to develop the event selection for the Cosmic-Ray Electron (CRE) analysi...

Providing a high quality and sufficient high current positron beam for the ultra high luminosity B-factory SuperB is a major goal. In this paper a proposition for positrons production and capture scheme based on low energy electrons up to 1 GeV is presented. For this technique, several types of flux concentrator used to capture the positrons are being studied. The following accelerating section...

Measurement of the helicity dependent elastic electron-proton scattering cross section provides a key means investigating parity violation within proton. However, such measurements exhibit potential instrumental effects associated with detection polarized recoiled protons. In particular, spin-orbit interactions massive detector induce systematic spatial shift in signal. this study, we determine...

The GATE 6.1 Monte Carlo simulation platform based on the GEANT4 toolkit is in constant 15 improvement for dosimetric calculations. Here, we explore its use for calculating internal absorbed dose distribution in mice for the treatment of malignant melanoma after injection of a new specific radiopharmaceutical labeled with iodine 131. We estimate the dosimetric accuracy of GATE 6.1, by calculati...
