Abstract (en)
[origin: WO2018046293A1] A device for examining a non-gaseous sample interacting with gases in an electron- and/or ion-optical system is provided, wherein the sample is arranged in a sample chamber and the sample chamber furthermore has a diaphragm having a hole-like aperture, and wherein a potential can respectively be applied to the sample and the diaphragm, as a result of which an electric field forms between the sample and the diaphragm, such that the sample and the diaphragm together form an electrostatic immersion lens, and the electrical potentials are selectable in such a way that discharges and/or electron and/or ion scattering are/is counteracted.
