We analyze the dependence of the Secondary Electron Emission yield on the beam incidence angle (theta) in the case of Faraday cups used for diagnosis of laser-plasma. We show that this dependence follows a sec(alpha)(theta) law, consequently theta not equal 0 situations (i.e. non-normal incidence) should be treated with care to avoid wrong measurements.

Abstract
We analyze the dependence of the Secondary Electron Emission yield on the beam incidence angle (theta) in the case of Faraday cups used for diagnosis of laser-plasma. We show that this dependence follows a sec(alpha)(theta) law, consequently theta not equal 0 situations (i.e. non-normal incidence) should be treated with care to avoid wrong measurements.File in questo prodotto:
