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.
