“…The measured total chargechanging cross sections showed good agreement with both the reference measurements and simulations using a model developed by Sihver et al [6]. In the case of the partial cross sections Sihver's model showed stronger energy dependence than our measurements, and deviated from our measurements in the lower energy region.…”

“…Several measurements of the charge-changing cross sections of carbon in water and tissue materials have been performed [4,5]. If compared to the predictions of different models [6,7,8,9,10,11], significant discrepancies are observed. Moreover, measurements of partial projectile fragmentation cross sections are scarce.…”

We have studied charged nuclear fragments produced by 200 -400 MeV/nucleon carbon ions, interacting with water and polycarbonate, using a newly developed emulsion detector. Total and partial charge-changing cross sections for the production of B, Be, and Li fragments were measured and compared with both previously published measurements, and model predictions. This study is of importance for validating and improving carbon ion therapy treatment planning systems, and for estimating the radiological risks for personnel on space missions, since carbon is a significant component of the Galactic Cosmic Rays.

“…We remark that the formula by Kox et al is applicable for a wider range of the incident energy including the low energy region where the Coulomb repulsion between the projectile and target takes effect, although it ignores resonance features which are also important in such a low energy region. We also remark that there is such a kind of formula as includes two adjustable energy dependent parameters [25,26,27].…”

Formula for Proton–Nucleus Reaction Cross Section at Intermediate Energies and Its Application

2007

We construct a formula for proton-nucleus total reaction cross section as a function of the mass and neutron excess of the target nucleus and the proton incident energy. We deduce the dependence of the cross section on the mass number and the proton incident energy from a simple argument involving the proton optical depth within the framework of a black sphere approximation of nuclei, while we describe the neutron excess dependence by introducing the density derivative of the symmetry energy, L, on the basis of a radius formula constructed from macroscopic nuclear models. We find that the cross section formula can reproduce the energy dependence of the cross section measured for stable nuclei without introducing any adjustable energy dependent parameter. We finally discuss whether or not the reaction cross section is affected by an extremely low density tail of the neutron distribution for halo nuclei.

During the last two to three years extensive development of the Geant4 simulation toolkit has occurred, which will culminate in a major release at the end of 2013. This development includes the adoption of multi-threading, the extension and improvement of physics models, improvements to the geometry modeler with a revised implementation of most geometrical primitives, advances in visualization and graphical user interfaces (GUI), the move from GNU make to CMake and the extension and automation of the Geant4 testing suite. The reasons for and implementation of multi-threading will be discussed. Certain electromagnetic and hadronic model extensions will also be discussed along with their effects on calorimeter results. Finally, visualization and GUI improvements will be highlighted along with the new configuration, build and testing systems.
