Measuring fluorescence photon counts of cosmic ray muons in scintillation fibers

open access: yesHe jishu, 2023
BackgroundIn the realm of cosmological ray studies employing plastic scintillation fibers, it is essential to conduct quantitative analyses of the photon number from the fiber's output pulse for the successful design of readout electronics.PurposeGiven ...

An iterating method to investigate the geometry of range modulation wheel in passive proton therapy [PDF]

open access: yesمجله علوم و فنون هسته‌ای, 2020
In the treatment of the  tumors using proton therapy, the synchrotron emits a monoenergetic beam that transports most of its energy in a special position after entering the target. There are two approaches to invading the entire tumor tissue.

Geant4 VMC 3.0 [PDF]

open access: yesJournal of Physics: Conference Series, 2015
Virtual Monte Carlo (VMC) [1] provides an abstract interface into Monte Carlo transport codes. A user VMC based application, independent from the specific Monte Carlo codes, can be then run with any of the supported simulation programs. Developed by the ALICE Offline Project and further included in ROOT [2], the interface and implementations have ...

Comparison between GEANT4 and MCNP for well logging applications [PDF]

open access: yesEPJ Web of Conferences, 2023
MCNP and GEANT4 are two reference Monte Carlo nuclear simulators, MCNP being the standard in the Oil & Gas nuclear logging industry. While performing a simulation benchmark of these two software for the purpose of “Cased Hole” wellbore evaluation ...

Calculation of spectrum and neutron flux density in experimental channels of WWR-M reactor

open access: yesЯдерна фізика та енергетика, 2021
A program for calculating the spectra and densities of neutron fluxes in the experimental channels of the research reactor WWR-M was developed. To do this, the reactor core was modeled. Irradiation of neutron activation detectors was performed.

Quantitative Test of the Evolution of Geant4 Electron Backscattering Simulation

open access: yes, 2016
Evolutions of Geant4 code have affected the simulation of electron backscattering with respect to previously published results. Their effects are quantified by analyzing the compatibility of the simulated electron backscattering fraction with a large ...

Investigation of The Gamma Ray Shielding Behaviour of (90-x)TeO2—xMoO3—10ZnO Glass System Using Geant4 Simulation Code and WinXCOM Database

open access: yesCumhuriyet Science Journal, 2019
In this study, mass attenuationcoefficients (µm), transmission fractions (T), mean free path (MFP) and halfvalue layer (HVL) of the (90-x)TeO2—xMoO3—10ZnOglass system (x=10, 20 and 30 mol%) were calculated at the gamma rayphoton energies of 356 keV, 662 ...

Extending Geant4 Parallelism with External Libraries (MPI, TBB) and Its Use on HPC Resources

open access: yes, 2015
With Geant4 Version 10.0, released in December 2013, one of the most widely used Monte-Carlo codes has been ported to take full advantage of multi- and many-core CPUs thanks to the introduction of event-level parallelism via multithreading. In this paper

Range Different of Mono-Energetic 290 MeV/u Carbon Ion Across Geant4 Version with Variation of I-values

open access: yesJPFT (Jurnal Pendidikan Fisika dan Teknologi)
The mean ionization potential (I-value) is a primary determinant of the position of the heavy ion Bragg peak. To minimize their impact on beam range errors and quantify their uncertainties, the currently used I-values in Geant4 material database are ...
