“…However, the Fermi break-up de-excitation model seems to give better results than the generalized evaporation model. This observation has also been done in Böhlen et al [11] and Ivanchenko et al [30].…”

“…Regarding the two exit channel models, the Fermi Break-up model seems, for a given entrance channel model, to be, in most cases, more compatible with the data. This was already mentioned in Böhlen et al [11] and Ivanchenko et al [30]. This is due, to some extent, to the fact that the Fermi Break-up description allows to explore more available phase space (especially at high excitation energies for which three (or more) body decay may play an increasing role) than the GEM model for which only sequential evaporation is taken into account.…”

“…In this report the calculations were conducted using the Monte Carlo methods. Although, the Monte Carlo methods are not able to precisely simulate the problems corresponding to the conditions in the real world, in studying the particles passage through the matter and nuclear interactions have been widely used as powerful and accurate tools in many applications of radiation researches, such as the ion therapy studies [29][30][31][32][33][34][35][36][37] . Thus, to obtain the most reliable results, the two Monte Carlo tools, the MCNPX introduced by Hughes, et al [38][39][40] and the GEANT4 by Agostinelli, et al [41][42][43][44] were used.…”

Proton therapy as a promising candidate in cancer treatment has attracted much attentions and many studies have been performed to investigate the new methods to enhance its radiation effectiveness. In this regard, two research groups have suggested that using boron isotopes will lead to a radiation effectiveness enhancement, using boron-11 agent to initiate the proton fusion reaction (P-BFT) and using boron-10 agent to capture the low energy secondary neutrons (NCEPT). Since, these two innovative methods have not been approved clinically, they have been recalculated in this report, discussed and compared between them and also with the traditional proton therapy to evaluate their impacts before the experimental investigations. The calculations in the present study were performed by Geant4 and MCNPX Monte Carlo Simulation Codes were utilized for obtaining more precision in our evaluations of these methods impacts. Despite small deviations in the results from the two MC tools for the NCEPT method, a good agreement was observed regarding the delivered dose rate to the tumor site at different depths while, for P-BFT related calculations, the GEANT4 was in agreement with the analytical calculations by means of the detailed cross-sections of proton-11 B fusion. Accordingly, both the methods generate excess dose rate to the tumor several orders of magnitude lower than the proton dose rate. Also, it was found that, the P-BFT has more significant enhancement of effectiveness, when compared to the NCEPT, a method with impact strongly depended on the tumor's depth. On the other hand, the advantage of neutron risk reduction proposed by NCEPT was found to give no considerable changes in the neutron dose absorption by healthy tissues.

“…These both allow for the modelling of protons, neutrons and pions, with BERT also being able to model kaons and hyperons. The energy ranges are 0 -15 GeV for BERT, and 0 -5 GeV for BIC [26]. The PhysicsList() used in this instance uses a combination of high precision neutron physics (HP), for the neutron interactions, and electromagnetic physics, for the electrons, and γ-rays within the simulation.…”

Comparison of CdZnTe neutron detector models using MCNP6 and Geant4

Abstract-The production of accurate detector models is of high importance in the development and use of detectors. Initially, MCNP and Geant were developed to specialise in neutral particle models and accelerator models, respectively; there is now a greater overlap of the capabilities of both, and it is therefore useful to produce comparative models to evaluate detector characteristics. In a collaboration between Lancaster University, UK, and Innovative Physics Ltd., UK, models have been developed in both MCNP6 and Geant4 of Cadmium Zinc Telluride (CdZnTe) detectors developed by Innovative Physics Ltd. Herein, a comparison is made of the relative strengths of MCNP6 and Geant4 for modelling neutron flux and secondary γ-ray emission. Given the increasing overlap of the modelling capabilities of MCNP6 and Geant4, it is worthwhile to comment on differences in results for simulations which have similarities in terms of geometries and source configurations.
