We present an implementation of crystal lattices and phonon transport using the Geant4 toolkit. We discuss basic phonon transport physics as and detailed implementation methods within Geant4 as well as results of our verification and validation effort.
The code discussed is capable of tracking acoustic phonons in arbitrary cryogenic crystals, as well as simulate isotope scattering, mode...

The nuclear interaction mechanism of carbon ions with nuclei represent a key point in the understanding of delivered dose in cancer therapy application. The effect of fragmentation diminishes the number of primary ions delivered to the region under treatment and produce a tail of damaging ionisation beyond the Bragg peak. In addition the trajectories of fragments may be sufficiently...

Nucleus-nucleus interactions have been acknowledged as of growing importance for simulations of aerospace radiation effects: energetic nuclei and nuclear fragments can have disproportionate effects both on the high-LET dose received during human spaceflight, and the single event threat to microelectronics in space and for aircraft in the upper atmosphere. Indeed, at high altitudes in the...

Objective
In order to evaluate space mission hazards, we need to understand the effects of ionizing radiation in the human body on a microscopic scale. DNA damages impact directly on the fate of irradiated biological cells. Early DNA damages result from physical, physico-chemical and chemical interactions on cellular DNA. In this study, we present the experimental irradiation of plasmid DNA...

We present an implementation of charge transport physics in cryogenically cold semiconductor crystals using the Geant4 toolkit. The code presented is capable of simulating the transport of electrons and holes within Germanium crystals, taking into account conduction band anisotropies and Luke-Neganov scattering.
We discuss the detailed implementation of charge transport physics presented,...
