| Zusammenfassung: | A particle-optical arrangement comprises
a charged particle source for generating at least one beam (311) of charged particles;
a first multi-aperture plate (613) having a plurality of apertures and a second multi-aperture plate (614) having a plurality of apertures, wherein the second multi-aperture plate is spaced apart from the first multi-aperture plate such that a gap is formed therebetween; and
a mounting structure (605) mounting the first multi-aperture plate relative to the second multi-aperture plate, wherein the mounting structure comprises at least one actuator (690) for adjusting a position of the first multi-aperture plate relative to the second multi-aperture plate. |
