An overview of the electromagnetic (EM) physics Geant4 toolkit is presented.Two sets EM models are available: "Standard" initially focused on high energy (HEP) while "Low-energy" was developed for medical, space and other applications.The provide a faster computation but less accurate keV energies, more CPU time consuming.A common interface to has been allowing natural combination ultra-relativistic, relativistic low-energy same run providing both precision performance.Due this migration...
Recent progress in development of single and multiple scattering models within the Geant4 toolkit is presented. Different options available to users are discussed. The comparisons with data shown. trade precision versus CPU performance discussed focus on LHC detectors simulation.
We report on developments of the Geant4 electromagnetic physics sub-libraries release 10.4 and beyond. Modifications are introduced to models photoelectric effect, bremsstrahlung, gamma conversion, single multiple scattering. The theory-based Goudsmit-Saunderson model electron/positron scattering has been recently reviewed a new improved version, providing most accurate results for electrons positrons, was made available. updated interfaces, configurations have already integrated into LHC...
Tissue equivalent materials (TEM) are frequently used in research as a means to determine the delivered dose patients undergoing various therapeutic procedures. They routine quality assurance and control procedures diagnostic physics. However, very few that tissue have been developed for use at low photon energies involved diagnosis radiology. The objective of this study is describe series TEMs designed radiographically imitate human energies. adipose, cortical bone, fat, lung, muscle...
In this work we report on recent improvements in the electromagnetic (EM) physics models of Geant4 and new validations EM physics. Improvements have been made photoelectric effect, Compton scattering, gamma conversion to electron muon pairs, fluctuations energy loss, multiple synchrotron radiation, high positron annihilation. The results these developments are included version 10.1 patches previous versions 9.6 10.0 that planned be used for production run-2 at LHC. validation suite has...
Current status of the Standard electro-magnetic (EM) package Geant4 toolkit is described. We report on stability results with respect to variation production threshold and Physics List. This illustrates trade between CPU time precision simulation predictions. New comparisons experimental data are shown. The benchmark discussed.
An overview of the electromagnetic physics (EM) models available in Geant4 toolkit is presented. Recent improvements are focused on performance detector simulation results from large MC production exercises at LHC. Significant efforts were spent for high statistics validation EM physics. The work consolidation was achieved providing common interfaces standard (HEP oriented) and low-energy (other application domains). It allows combination ultra-relativistic, relativistic any processes. With...
We report on the recent progress within Geant4 electromagnetic physics subpackages. Several new interfaces and models recently introduced are already used in LHC applications may be useful for any type of simulation. Significant developments were carried out to improve user interface, develop single multiple scattering, validate high energy models. Part these included 10.2 release full set available version 10.3 December, 2016.
The Geant4 electromagnetic (EM) physics sub-packages are a component of LHC experiment simulations. During long shutdown 2 for LHC, these packages under intensive development and we report progress EM in versions 10.5 10.6, which includes faster computation, more accurate models, extensions to the validation suite. New approaches developed simulate radiation damage silicon vertex detectors configuration multiple scattering per detector region. Improvements user interfaces low-energy...
The computational voxel phantom 'High-Definition Reference Korean-Man (HDRK-Man)' was implemented into the Monte Carlo transport toolkit Geant4. model, adjusted to Korean Man, is 171 cm in height and 68 kg weight composed of ∼30 million voxels whose size 1.981 × 2.0854 mm3. Geant4 code then utilised compute dose conversion coefficients (DCCs) expressed absorbed per air kerma free for >30 tissues organs, including almost all organs required new recommendation ICRP 103, due a broad parallel...
