Reflection of a Charged Particle Beam from a Material Medium in 3D Geometry
摘要
Abstract
The concept of flow lines was used in the past to find an analytical solution of the problem of reflection of charged particle beams from a flat interface of a vacuum and an arbitrary material medium. It had been also shown that the stochastic process of multiple Coulomb scattering in the given geometry is described by a distribution function that coincides with the one that is formed when a given beam propagates in an infinite medium. An attempt is made to calculate the coefficient and reflection angle of a charged particle beam when in the case of oblique incidence on the interface between a vacuum and a material medium, taking into account the 3D geometry of the problem.
