introduction use of hadron therapy as an advanced radiotherapy technique is increasing. in this method, secondary particles are produced through primary beam interactions with the beam-transport system and the patient’s body. in this study, monte carlo simulations were employed to determine the dose of produced secondary particles, particularly neutrons during treatment. materials and methods i...

The dominant background for observations of γ-rays in the energy region above 50 GeV with Imaging Atmospheric Cherenkov telescopes are cosmic-ray events. The images of most of the cosmic ray showers look significantly different from those of γ-rays and are therefore easily discriminated. However, a small fraction of events seems to be indistinguishable from γ-rays. This constitutes an irreducib...

Every 10 s, the antiproton-production-target will be bombarded by a pulse of 2×10 primary protons with an energy of 29 GeV (for an overview see [1]). This corresponds to a total beam power of about 10 kW. After passing of the first dipole primary protons and antiprotons are no longer in-line and the primaries have to be dumped. Behind the target a significant part of the beam power is carried b...

Secondary particles produced in spallation reactions of cosmic rays with the interstellar gas provide valuable information that allow us to investigate injection and transport charged Galaxy. A good understanding cross sections production these is crucial correctly interpret our models, although existing experimental data very scarce uncertain. We have developed a new set sections, both inelast...

The structure of the framework is presented schematically in Fig. 1. The main class FairRunManger handles the overall program flow and the communication between different modules, namely Geometry Interface, RunTime DataBase , Event Generators, IO Manager and the Virtual Monte Carlo. The latter is an interface to differents Monte Carlo engine (Geant3, Geant4 and Fluka) allowing the user to choos...

LCLS Matter in Extreme Conditions (MEC) Instrument is an X-ray instrument that will be able to create and diagnose High Energy Density (HED) matter. The MEC laser system can generate hard X-ray due to the interaction of the laser and the plasma. This paper summarizes results of the shielding calculations performed to evaluate the radiation hazards induced by this hard X-ray source with Monte Ca...

[1] We present a physical model to calculate production of cosmogenic isotope Be in the atmosphere. The model is based on a full Monte Carlo simulation of an electromagneticmuon-nucleonic cascade in the atmosphere, using CORSIKA and FLUKA packages. The present results are in broad agreement with earlier empirical and semiempirical models but predict higher production rate than some recent theor...
