Abstract:
Distributions of electron characteristics for modeling their transport in
matter are obtained with the use of cross-section data on elastic and
inelastic processes. The developed model does not use the well-known slow-down
approximation and the multiscattering theory of electron transport. Statistical
algorithms for modeling of electron transport are proposed to perform numerical
experiments on hybrid supercomputers. In particular, these algorithms use the
NVIDIA CUDA technology. A number of numerical experiments are performed to study
the interaction between electrons and a target matter of an X-ray tube on an
MVS cluster (http://www.kiam.ru/MVS/resourses/mvse.html) and on a new supercomputer
K-100.
