Abstract: A computer-implemented method of processing image data according to the present disclosure comprises: receiving the image data, wherein the image data is scanning transmission charged-particle microscope (STCPM) image data representing a STCPM scan obtained at a first focus depth; and processing a system of equations expressing the image data as a sum of contributions from a plurality of slices of the sample at a plurality of focus depths, wherein each equation of the system of equations relates at least a portion of the image data to: at least one of a plurality of contrast transfer functions of the STCPM, each contrast transfer function of the STCPM being determined at a different respective focus depth; and at least one set of unknown objects of the STCPM, each unknown object in a set being at a different respective focus depth. The step of processing comprises solving the system of equations to obtain at least one of the plurality of unknown objects of the STCPM.

Abstract: 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.

Abstract: A method for the control of a controllable aggregate, in particular a transmission of a motor vehicle, in which to form at least one determinant magnitude various or varying numbers of contributions from delivery objects are taken into account, at least two different delivery objects being provided, by way of which respective contributions for the determination of the determinant magnitude are determined and such that a counter is provided, to which the contributions by all the delivery objects are sent. The counter evaluates each contribution by way of a weighting and sends it to an evaluating mechanism and this evaluating mechanism determines the determinant magnitude from the evaluated contributions. In addition, the invention concerns a control unit for the control of a controllable aggregate in accordance with such a method and an aggregate with such a control unit.

Abstract: The invention relates to a method and a device for the generation of a plasma through electric discharge in a discharge space which contains at least two electrodes, at least one of which is constructed from a matrix material or carrier material, such that an erosion-susceptible region with an evaporation spot is formed at least by the current flow. To present a method or a device for the generation of a plasma by electric discharge, it is suggested that a sacrificial substrate (38) is provided at least at the evaporation spot, the boiling point of said lying below the melting point of the carrier material (30), such that charge carriers arising in the current flow are mainly generated from the sacrificial substrate (38).
