An approach to computing the cascade processes is developed. The approach has three key properties allowing the effective use of heterogeneous structure of computers for solving the tasks of radiation transport in complex multi-scale geometries. Firstly, two different discreet geometrical description of an object being under radiation is used: triangulated model for photon transport and voxel model for electron transport. Secondly, small parameter of the problem is explicitly taking into account for modeling surface effects (for instance, electron emission). Thirdly, the effective calculation decomposition between CPU and GPU is developed for significant increasing the speed of calculations of processes in question. Modeling of experiment on researching the bremsstrahlung generated by electron beam in Ta target is carried out. Comparison of computing and experimental results shows satisfactory consent.

A1 - Podoliako, Serguei A1 - Jaenisch, Gerd-Rüdiger A1 - Bellon, Carsten T1 - Numerical Simulation of X-Ray Scattering Processes during Radiographic Inspection of Materials JF - Russian journal of nondestructive testing N2 - Abstract A technique for numerical simulation of the processes of forming X-ray radiography images of complex multicomponent objects with allowance for the penetrating-radiation absorption and scattering processes is proposed. The technique proposed is based on an efficient description of complex 3D objects with piecewise-homogeneous structures and uses precisely specified shells separating homogeneous components of an object. Being combined with a developed version of the Monte Carlo method, this approach yields an efficient computational apparatus for analyzing the regularities of the formation of radiographic images of objects’ internal structures. This apparatus is intended for state-of-the-art multiprocessor computing systems. Having been obtained via the technique developed, the results of the numerical analysis of the effect of different mechanisms of interaction between photons and matter (including coherent and incoherent scattering with allowance for bonds of electrons in atoms) on the formed radiographic image of the object’s internal structure are discussed. The advantage of the described technique over the known MCNP program complex is shown.

T1 - Mathematical modeling of radiography experiments T2 - 18th WCNDT - World conference on nondestructive testing (Proceedings) N2 - An approach is presented to construct operators for transforming the characteristics of incident radiation to transmitted radiation, as well as operators for transforming the transmitted radiation to measured values. Simu-lating the radiation transport is based on Monte Carlo modeling of the interaction of X-ray photons and electrons with matter. The proposed method permits to construct, for instance, the operator connecting the initial radiation spectrum with the absorbed photon energy penetrating a given object. The elaborated approach provides the possibility of effective mathematical modeling of radiation techniques such as radiography, treating complex multi-component objects. Moreover, the method can be used to construct the operator equation for solving in-verse problems, e.g. the reconstruction of the initial radiation spectrum using simple experimental measure-ments. Comparison with some experimental measurements is presented.

T1 - Monte Carlo modeling of electron transport using CUDA technology T2 - 18th WCNDT - World conference on nondestructive testing (Proceedings) N2 - Statistical algorithms are presented for modeling the interaction processes between electrons and matter. A software implementation has been developed for hybrid supercomputers making use of NVIDIA© CUDA© technology. Standard Monte Carlo schemes are modified for effectively exploiting the parallel computing capabilities of graphical processors. The model of individual collisions (MIC) is used to describe the interaction of electrons with atoms. This model does not include the approximations assumed in multiple collision theory or the continuous slow down approach with the Landau theory for energy-loss fluctuations. The distributions of electron characteristics are obtained from tabulated electron cross section data. The examples discussed in this paper demonstrate the applicability of the algorithms to investigating the interaction of electrons with X-ray tube targets producing Bremsstrahlung. The proposed technique can be used for mathematical modeling in radiography.
