Geant4 quartz fiber simulations as part of luminometer development for CMS

4D geomechanical simulations for field development planning

3D and 4D geomechanical can be time-consuming to build and calibrate. However, once such a model is built, it is relative straightforward to use this model for various field development and management applications. In so doing, the return on the initial investment of time and effort in the creation of a 4D geomechanical model can be substantial. I present a case study where a 4D geomechanical m...

GEANT4 Tuning For pCT Development

Proton beams in medical applications deal with relatively thick targets like the human head or trunk. Thus, the fidelity of proton computed tomography (pCT) simulations as a tool for proton therapy planning depends in the general case on the accuracy of results obtained for the proton interaction with thick absorbers. GEANT4 simulations of proton energy spectra after passing thick absorbers do ...

Homework #10 Geant4 Simulations for Compton Scattering in Aluminum

Compton scattering models in Geant4 are the following: a.) G4ComptonScattering: listed as ”compt” in the process name. No Rayleigh scattering in the model. b.) G4LowEnergyCompton: Process name is ”LowEnCompton” in the tracking code. It has errors in the treatment of Rayleigh scattering and does not account for Doppler broadening (the effect of bound electron momentum on the scattered particle e...

GEANT4 Target Simulations for Low Energy Medical Applications

The GEANT4 code offers an extensive set of hadronic models for various projectiles and energy ranges. These models include theoretical, parameterized and, for low energy neutrons, data driven models. Theoretical or semiempirical models sometimes cannot reproduce experimental data at low energies (<100MeV), especially for low Z elements, and therefore recent GEANT4 developments included a new pa...
