Secondary electron emission properties [PDF]
Philips Journal of Research, 1996 Abstract In this paper an introduction is given to secondary electron emission properties. It is shown that the reduced secondary emission yield δ δ m as a function of the reduced primary energy E p E m can be described by a universal curve.

Probabilistic model for the simulation of secondary electron emission
Physical Review Special Topics. Accelerators and Beams, 2002 We provide a detailed description of a model and its computational algorithm for the secondary electron emission process. The model is based on a broad phenomenological fit to data for the secondary-emission yield and the emitted-energy spectrum.
