Abstract
The efficiency of secondary emission monitors for electron beams has been calculated. Starting from the Möller cross section, the secondary electrons are considered as creators of tertiary electrons of which those coming out of the monitor foils lead to a first term F1(E) that is a function of the energy E of the primary electron, but practically independent of the foil thickness ξ. A second term F2(E, ξ), depending on energy and thickness of the foil, is obtained by considering the secondary electrons that leave the foil. From say 10 MeV on, the efficiency can be written as G(ξ) + α ln E,G being a function of ξ only and α being a constant. Comparison with experiment in the energy regions 0.5–3.5 MeV, 15–40 MeV, 100–600 MeV, leads to a fairly good agreement.
