The capability to accurately model the production of secondary neutrons from protons interacting with matter is of tremendous importance in Proton Therapy. These neutrons are the major source of secondary doses delivered to a patient during treatment. They also represent the most important contribution to the ambient doses remaining outside the biological shielding. They also constitute an...

In 1974, Nelson, Kase, and Svensson published an experimental investigation on muon shielding around SLAC high energy electron accelerators (NIM 120 (1974) 413). They measured muon fluence and absorbed dose induced by 14 and 18 GeV electron beams hitting a copper/water beamdump and attenuated in a thick steel shielding. In their paper, they compared the results with the theoretical models...

The performance of the Monte Carlo code system PHITS is validated for heavy ion transport capabilities by performing simulations and comparing results against experimental data from heavy ion reactions of benchmark quality. These data are from measurements of isotope yields produced in the fragmentation of a 140 MeV/u 48Ca beam on a beryllium target and on a tantalum target. The results of...

Geant4 is a toolkit for the simulation of the passage of particles through matter. To show its capability in the shielding area, we have submitted Geant4 results for the ”Inter comparison Problems of Neutron Attenuation” to SATIF organizers since 2006. Version 10 is the latest and major update of Geant4 and is publicly available since December 2013. Because it is a major update, there are...
