PARTICLE-OPTICAL SYSTEMS AND ARRANGEMENTS AND PARTICLE-OPTICAL COMPONENTS FOR SUCH SYSTEMS AND ARRANGEMENTS

摘要

A particle-optical component comprises at least one multi-aperture plate having a plurality of apertures formed therein, each for manipulating particles of a charged particle beamlet passing therethrough; wherein the multi-aperture plate comprises plural conductive layer portions arranged substantially in a single plane, wherein plural apertures are formed in each of the plural conductive layer portions, and wherein a resistant gap is formed between adjacent conductive layer portions.
