Abstract

A charged particle beam source device adapted for generating a charged particle beam is provided. The charged particle beam source device includes an emitter tip adapted for providing charged particles. Furthermore, an extractor electrode having an aperture opening is provided for extracting the charged particles from the emitter tip. An aperture angle of the charged particle beam is 2 degrees or below the aperture angle being defined by a width of the aperture opening and a distance between the emitter tip and the extractor electrode, wherein the distance between the emitter tip and the extractor electrode is a range from 0.1 mm to 2 mm.
