MULTI-BEAM SCANNING TRANSMISSION CHARGED PARTICLE MICROSCOPE

Techniques for multi-beam scanning transmission charged particle microscopy are disclosed herein. An example apparatus at least includes a charged particle beam column to produce a plurality of charged particle beams and irradiate a specimen with each of the plurality of charged particle beams, and an imaging system to collect charged particles of each of the charged particle beams of the plurality of charged particle beams that traverse the specimen during said irradiation, and to direct each charged particle beam of the plurality of the charged particle beams after traversing the sample onto a detector, where each charged particle beam includes a barycenter, and where the detector is disposed in an intermediate location between a back focal plane and an imaging plane of the imaging system.
