چکیده
Abstract Purpose. The purpose of this work is to investigate the feasibility TOPAS-nBio for track structure simulations using tuple scoring and ROOT/Python-based post-processing. Materials methods. There are several example applications implemented in GEANT4-DNA demonstrating simulations. These examples not by default TOPAS-nBio. In study, scorer was used re-simulate these examples. contained investigations different physics lists, calculation energy-dependent range, stopping power, mean free path W -value. Additionally, further tool were investigated, focusing on physical interactions deposited energies electrons with initial range 10–60 eV, covered recently published Low-energetic currently great interest radiobiology research community due their high effectiveness towards induction biological damage. Results. quantities calculated show a good agreement deviations 5% at maximum. Thus, we have presented feasible way implement included With extended simulations, an insight could be given, which tracking information can gained code how cross sections models influence particle’s fate. Conclusion. our results, potentials applying Monte Carlo Using scorer, large amount about accessed, analyzed as preferred after simulation.

Monte Carlo track simulations
Monte Carlo track structure simulations follow the primary as well as all produced secondary particles event-by-event, from starting or ejection energy down to total stopping. Simulation codes require both transport models and reliable interaction cross sections for the primary and secondary particles with the material under consideration. In general, charged particles can scatter elastically (...
متن کاملComparison of nanodosimetric parameters of track structure calculated by the Monte Carlo codes Geant4-DNA and PTra.
The concept of nanodosimetry is based on the assumption that initial damage to cells is related to the number of ionizations (the ionization cluster size) directly produced by single particles within, or in the close vicinity of, short segments of DNA. The ionization cluster-size distribution and other nanodosimetric quantities, however, are not directly measurable in biological targets and our...

PURPOSE To develop a nano-dosimetric Monte Carlo simulation package, TOPAS-nBio, based on the TOPAS (TOol for PArticle Simulations) framework that is being developed in a collaboration between the Massachusetts General Hospital (MGH), the SLAC National Accelerator Laboratory and the University of California, San Francisco. The goal is to incorporate biological processes on a sub-cell level that...
متن کاملinvestigating the feasibility of a proposed model for geometric design of deployable arch structures
deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...
