The production of neutrons by cosmic-ray muons at large depths underground is discussed. The most recent versions of the muon propagation code MUSIC, and particle transport code FLUKA are used to evaluate muon and neutron fluxes. The results of simulations are compared with experimental data. r 2003 Elsevier Science B.V. All rights reserved. PACS: 96.40.Tv; 25.40.Sc; 25.30.Mr; 28:20: v

The HESR facility will be built in the frame of the FAIR project. For the reason of safety radiation fields have to be considered for the building design. Radiation produced by lost proton and antiproton beams can be dangerous for personnel and equipment. Thus a beam line, where those losses can appear, must be properly shielded by concrete, soil, etc. A FLUKA [1] simulation was done to estimat...

This Note describes calculations of the shielding necessary to reduce the dose rate to less than 0.05 mrem/h when synchrotron radiations emitted by the LCLS electrons beam hit a worst type scattering target located in the hard X-ray line. The calculations were performed using the FLUKA Monte-Carlo code and as well as the STAC8 analytical code. The photon spectrum used as a source term correspon...

The 3–dimensional (3–D) calculation of the atmospheric neutrino flux by means of the FLUKA Monte Carlo model is here described in all details, starting from the latest data on primary cosmic ray spectra. The importance of a 3–D calculation and of its consequences have been already debated in a previous paper. Here instead the focus is on the absolute flux. We stress the relevant aspects of the ...

To devise an activation technique for characterizing mixed radiation fields, secondary particles from a copper target irradiated by 24 GeV/c protons were measured at the CERN High-energy AcceleRator Mixed field facility (CHARM). Activation detector sets consisting of aluminum, niobium, indium, and bismuth, placed 30 cm angles 15° to 160° with respect beam axis. The nuclides generated in these d...

A review of the strategy and the results for the physics validation of Geant4 and Fluka detector simulation engines for LHC applications is presented. The main focus is on hadronic physics, where most of the efforts are currently concentrated. In particular, comparisons between simulation and test-beam data for the most relevant calorimeter observables, for different experiments and detector te...

NASA has recognized the need for making additional heavy-ion collision measurements at the U.S. Brookhaven National Laboratory in order to support further improvement of several particle physics transport-code models for space exploration applications. FLUKA has been identified as one of these codes and we will review the nature and status of this investigation as it relates to high-energy heav...
