Oral presentation Users Workshop

From version 9.2 of Geant4, the LowEnergy electromagnetic processes (Livermore and Penelope) have been migrated to the design introduced for the Standard EM models. In the new approach there is only one process and multiple models that can be registered to the process. We present a validation of the migrated Geant4 electromagnetic photon models for elements and compounds with respect to...

130. Evaluation of absorbed fractions for beta-gamma radionuclides in ellipsoidal volumes of soft tissue through Geant4

Oral presentation Users Workshop

We developed a simulation in Geant4 to calculate the absorbed fractions for monoenergetic and beta electrons emitted by 199Au, 177Lu, 131I, 153Sm, 186Re and 90Y and for photons between 10 keV and 1 MeV, emitted by sources uniformly distributed in ellipsoidal volumes of soft tissue. Code validation results with respect to reference data for doses, ranges and absorbed fractions in spheres are...

Oral presentation Users Workshop

WArP is a double phase Dark Matter experiment using Liquid Argon as a target. In order to efficiently collect the 128 nm scintillation light a very careful light collection system, made by a wavelength shifter and a dielectric mirror, is used. A detailed & complete GEANT4 simulation of the detector has been performed, from particle interaction to PMTs photon detection. Optical photons...
