Stochastic broadening for 100-keV and 2.5-MeV electrons. (a) The stochastic lateral broadening of a continuous electron beam (initial diameter 200 μm) focused towards a point over a distance of 10 cm, calculated using the formulas of Kruit and Jansen [33] for an electron kinetic energy of 100 keV. (b) The corresponding quantities for 2.5-MeV electrons, together with the associated energy broadening (triangles).
