TLDR
It is demonstrated that EGSnrc allows for an artifact free Monte Carlo simulation of ion chamber response and backscattering, situations that have been considered in the past as the two of the most stringent tests of condensed history Monte Carlo codes.Abstract:
In this report a new EGS4 version, called EGSnrc to reflect the substantial changes made to the original code is reported, which incorporates a new any-angle multiple elastic scattering theory, an improved electron-step algorithm, a correct implementation of the fictitious cross section method for sampling distances between discrete interactions, a more accurate evaluation of energy loss, as well as an exact boundary crossing algorithm It is demonstrated that EGSnrc allows for an artifact free Monte Carlo simulation of ion chamber response and backscattering, situations that have been considered in the past as the two of the most stringent tests of condensed history Monte Carlo codes A detailed discussion of the effect of the various components of the condensed history simulation of electron transport on the simulated ion chamber response is given in the accompanying paperread more

Multiple Scattering of Electrons
S. Goudsmit,J. L. Saunderson +1 more
TL;DR: In this paper, a theoretical treatment of multiple Rutherford scattering is given which is exact if one considers electrons with the same total path length in the scatterer, and it is shown that this distribution depends in a sensitive way upon the deviation from the Rutherford law for small angle scattering due to screening by electrons.

Multiple Scattering in an Infinite Medium
TL;DR: In this paper, the integro-differential diffusion equation of the multiple scattering problem in an infinite, homogeneous, medium is studied without the usual small-angle approximation, and an expansion in spherical harmonics is carried out which is rapidly convergent in the case of large-angle scattering, whose coefficients can be exactly determined, and leads to expressions for the various moments of the spatial and angular distributions.
