    摘要: A charged particle energy analyzer includes two hemispherical electrodes and means for developing an inverse square electric field in the gap between the two electrodes. An afocal charged particle lens arrangement is arranged to project a charged particle image of a sample into the electric field. Two baffles are disposed in the gap between the electrodes the baffles being effective to restrict the energy and angular divergence of the particles transmitted by the analyzer, the baffles being positioned so as to reduce the dependence of the energy and the orientation of the charged particles transmitted by the baffles on the position of the particles within the image. A two-dimensional detector is arranged to detect the charged particle image transmitted by the analyzer.

    摘要: The invention is directed to an electron energy filter which is assembled from three or four plates placed together in a sandwich-like configuration. The pole pieces are seated on the inner sides of the outer plates and attached thereto. The pole pieces can therefore be produced in pairs so that their outer surfaces match precisely. This assembly is economical and provides a precise manufacture.

    摘要: A device for providing an energy filtered charged particle image particularly an electron image in the form of an electron energy analyzer which acts as a band-pass filter whilst maintaining the spatial integrity of the electron image in a uniform magnetic field. It embodies new electron optical properties wherein image electrons injected parallel to the magnetic field are guided, using crossed electrostatic and magnetic fields, to a low-pass electron mirror and then through a high-pass retardation filter. Non-uniform electrostatic deflection fields are used to compensate for the energy-dependent dispersion of the crossed fields whereby it is possible to correct for image distortion resulting from such dispersion.

    摘要: A spectrometer objective is composed of a short focal length, asymmetrical objective lens comprising an integrated electrostatic opposing field spectrometer and a single-stage deflection system arranged within the magnetic lens. Since the deflection of primary electrons occurs within the spectrometer objective, the space for a two-state deflection system employed in conventional systems between a condenser lens and an objective lens can be eliminated. The extremely-short structural length of the electron beam measuring apparatus which is thereby obtainable, in turn, has a beneficial effect on the influence of the lateral Boersch effect on probe diameter, this influence increasing with the length of the electron-optical beam path.

    摘要: An electrostatic opposing field spectrometer has an extraction electrode (AN) and an opposing field electrode arrangement with a pair of planar opposing field electrodes (EG1 and EG2) mounted to an outer electrode part (EM) at either end of a truncated conical shaped bore extending therethrough, where the smaller opening of the bore is in the direction of the extraction electrode (AN). The planar opposing field electrodes (EG1 and EG2), in conjunction with the bore surface, generates substantially spherical equi-potential lines (A1 and A2) which transmit a larger solid angle distribution of secondary electrons (SE) triggered at a measuring point (M) on the specimen surface (PR).

    摘要: Ions emitted from an ion source are dispersed by a dispersion means, and those ions of a predetermined mass number are extracted from the thus-dispersed ions and are selectively implanted into a sample. A plane of incidence of ions in the mass-dispersing means is so formed that the angle of incidence of ions thereon has a negative value, and a plane of emission of ions therein is so formed that the angle of emission of ions of the predetermined mass number therefrom has a positive value.

    摘要: For dark-field imaging of the specimen, a scanning corpuscularbeam microscope is equipped with multiple annular apertures located between the beam source and the specimen on the one hand and between the specimen and the detector on the other hand. The areas of the multiple annular apertures conjointly i.e. complementarily cover the ray path. The aperture situated in front of the detector is surrounded by a wide, radiationtransmitting region. The invention affords utilizing for the generation of the image not only the rays scattered outside of the aperture cone but also a large part of the rays scattered within this cone.
