    摘要: A multi-beam particle beam system includes a multi-aperture plate having a multiplicity of apertures. During operation, one particle beam of the plurality of particle beams passes through each of the apertures. A multiplicity of electrodes are insulated from the second multi-aperture plate to influence the particle beam passing through the aperture. A voltage supply system for the electrodes includes: a signal a generator to generate a serial sequence of digital signals; a D/A converter to convert the digital signals into a sequence of voltages between an output of the D/A converter and the multi-aperture plate; and a controllable changeover system, which feeds the sequence of voltages successively to different electrodes.

    摘要: The present invention concerns a charged-particle multi-beamlet system that comprises a source of charged particles (301); a first multi-aperture plate (320) having plural apertures disposed in a charged particle beam path of the system downstream of the source; a first multi-aperture selector plate (313) having plural apertures; a easier (340), wherein the first multi-aperture selector plate is mounted on the carrier; and an actuator (350) configured to move the carrier such that the first multi-aperture selector plate is disposed in the charged particle beam path of the system downstream of the source in a first mode of operation of the system, and such that the first multi-aperture selector plate is disposed outside of the charged particle beam path in a second mode of operation of the system. The source, the first multi-aperture plate and the carrier of the system are arranged such that a first number of charged particle beamlets is generated at a position downstream of both the first multi-aperture plate and the first multi-aperture selector plate in the first mode of operation, and that a second number of charged particle beamlets is generated at the position in the second mode of operation, wherein the first number of beamlets differs from the second number of beamlets.

    摘要: A multi-beam particle microscope includes first particle optics in order to direct particle beams onto an object, a detector with detection regions, with a transducer being assigned to each detection region, and a data acquisition system, which has a control computer system, image recording computer systems and a screen. The image recording computer systems receive electrical signals from the transducers and generates a first file, which represents a high resolution image, and a second file, which represents a low resolution image. The control computer system maintains a data structure which represents an assignment of transducers to two-dimensional spatial vectors and depicts the images on the screen, wherein a reference point in each image is arranged on the screen in a coordinate system of the screen at a location which is defined by a sum of a leading vector, which is the same for all images, and the spatial vector.
