The aim of this study is to determine an optimal shielding of the LINAC4 beam dump fulfilling the radiation protection requirements. Therefore a detailed Monte-Carlo calculation using FLUKA particle transport and interaction code has been performed and the relevant physics quantities, such as particle fluences, neutron energy spectra, residual and prompt dose rates, air and water activation hav...

Typical neutron spectra as found at high energy electron accelerators outside concrete shielding of various thicknesses (at 90 degrees) have been calculated at three electron energies (100 MeV, 1 and 10 GeV) with the FLUKA Monte Carlo transport code. The results have provided useful information about neutron attenuation lengths and about the fraction of neutrons with energy larger than 20 MeV, ...

The FLUKA Monte Carlo code, presently used in cosmic ray physics, contains packages to sample soft hadronic processes which are built according to the Dual Parton Model. This is a phenomenological model capable of reproducing many of the features of hadronic collisions in the non perturbative QCD regime. The basic principles of the model are summarized and, as an example, the associated Λ–K pro...

The FLUKA Monte Carlo program is used to predict the distributions of the muons which originate from primary cosmic gamma rays and reach sea level. The main result is the angular distribution of muons produced by vertical gamma rays which is necessary to predict the inherent angular resolution of any instrument utilizing muons to infer properties of gamma ray primaries. Furthermore, various phy...

The activity concentration for various radionuclides produced in the soil around the collimation section of the Beam Delivery System for the Next Linear Collider is calculated using the FLUKA Monte Carlo code. Different methods are used to calculate the activity concentration of H, Na and Be in soil. The activity concentration of H and Na in groundwater are also calculated and compared with the...

This paper is a continuation of the preliminary dosimetric evaluation of source terms at PW laser systems [1] the proton case. The main acceleration mechanisms and the associated characteristics of the accelerated proton beams were briefly presented. FLUKA and GEANT4 Monte Carlo transport codes were used to compute absorbed doses due to three proton beams of well defined energy and spatial dist...

The planned new Heavy Ion Synchrotron SIS 100/300 for the FAIR Project will consist of two separate tunnels. In addition to the tunnel where the beam lines itself will be situated, there will be an additional tunnel, for maintenance and supply purposes. This maintenance tunnel is desired to be accessible for technical personnel also during beam operation. Therefore, from the radiation safety po...
