The simulation toolkit GEANT4 has been used to create high-level tools for specific user groups, such as SPENVIS in space physics and GATE in medical imaging. In Accelerator Physics, comparable efforts are being devoted to develop general-purpose programs for simulating beam lines and accelerators, allowing access to Geant4’s facilities for 3D geometry, tracking, and interactions in matter with...

The study of beam transport is of central importance to the design and performance assessment of modern particle accelerators. In this paper, we benchmark two contemporary codes, DIMAD and BDSIM, the latter being a relatively new tracking code built within the framework of GEANT4. We consider both the 20 mrad and 2 mrad extraction lines of the 500 GeV International Linear Collider (ILC) and we ...

The treatment protocols of cancerous ocular diseases with proton therapy are well established, and dedicated eye-treatment systems can produce the clinical beam properties that meet peculiar features required by modalities. However, for general-purpose multiroom comprising beamlines nozzles, design commissioning procedures must be optimized to achieve performances fully in terms depth-dose dist...

Abstract IMPACT (Isotope and Muon Production with Advanced Cyclotron Target Technologies) is a proposed initiative envisaged for the high-intensity proton accelerator facility (HIPA) at Paul Scherrer Institute (PSI). As part of IMPACT, radioisotope target station, TATTOOS (Targeted Alpha Tumour Therapy Other Oncological Solutions) will allow production terbium radionuclides therapeutic diagnost...

با توجه به اینکه براساس آزمایش‌ها و شواهد موجود تنها 4 درصد جهان قابل رویت است و 96 درصد باقیمانده از ماده و انرژی تاریک تشکیل یافته بنابراین فیزیکدانان برای پی بردن به حقیقت جهان به استفاده از شتابدهنده‌ها روی آوردند. یکی از قدرتمندترین شتابدهنده‌های پیشنهاد شده برای این امرکه به عنوان جایگزین شتابدهنده LHC مورد توجه است، شتابدهنده ILC می‌باشد که در ابتدا قادر خواهد بود ذرات را تا انرژی برخورد...

Abstract Due to the advancement of proton therapy for cancer treatment, there has been a worldwide increase in construction treatment facilities. Therapy centres are often coupled with clinical, biological or material-science research programs. Research activities require beams at energies spanning an extensive range higher beam currents and longer irradiation times than clinical conditions. Ad...

The Geant4 Visualisation System is a multi-driver graphics system designed to serve the Geant4 Simulation Toolkit. It is aimed at the visualization of Geant4 data, primarily detector descriptions and simulated particle trajectories and hits. It can handle a variety of graphical technologies simultaneously and interchangeably, allowing the user to choose the visual representation most appropriat...

geant4 is an open source simulation toolkit based on c++, which its advantages progressively lead to applications in research domains especially modeling the biological effects of ionizing radiation at the sub-cellular scale. however, it was shown that geant4 does not give a reasonable result in the prediction of antiproton dose especially in bragg peak. one of the reasons could be lack of a re...

This paper describes PDB4DNA, a new Geant4 user application, based on an independent, crossplatform, free and open source C++ library, so-called PDBlib, which enables use of atomic level description of DNA molecule in Geant4 Monte Carlo particle transport simulations. For the evaluation 15 of direct damage induced on the DNA molecule by ionizing particles, the application makes use of an algori...
