Abstract

A method of operating a particle beam system comprises positioning a sample at a given distance away from a lens focusing a particle beam; performing a measurement for each selected energization of a plurality of measurement energizations, wherein each measurement comprises recording a value derived from a reading of an electron detector, while the lens is energized with a selected measurement energization; and analyzing a dependency of the recorded values from the plurality of measurement energizations. Herein analyzing is based on a dependency of the number of electrons incident on the electron detector per unit time from the distance of the sample from the lens and from the energization of the lens.
