    Abstract: An electron microscope provided with an electron source; an energy-dispersive element; an accelerating tube; a plate mounted between the energy-dispersive element and the specimen, in which a selection slit is provided at right angles to the dispersive direction of the dispersive element; source imaging electron optics for obtaining an image of a source in the plane of the plate comprising the selection slit. In addition to the selection slit, the plate comprises a plurality of further apertures useful for the determination of the cross-sectional form of the beam; and the electron microscope comprises means for the determination of the intensity of the beam being transmitted through and/or onto the plate, so that subject thereto, setting parameters of the energy-dispersive element and the source imaging electron optics can be aligned. The dimensions of the apertures are in the nanometric range and the plate constitutes a thin membrane placed at a position where the electron's kinetic energy is so low that it can be blocked by the thin membrane. Further, the plate is positioned directly after the energy-dispersive element and the source imaging electron optics.

    Abstract: Apparatus for acting upon charged particles has particular application in a mass analysis apparatus. An array of elongate magnetic poles (311) extends longitudinally in the direction of a longitudinal axis (350) of the array, the array having a symmetrical reference surface (320) containing the longitudinal axis and passing through the array with magnetic poles (311) on each side of the reference surface. Charged particles (314) enter into, or originate in, the field of the magnetic pole array at a position spaced from the said longitudinal axis (350). The array of magnetic poles is such as to provide between opposed poles (311A, 311B), an extended region of magnetic field in which the charged magnetic particles pass with a curved motion imposed thereon by the field, together with entry and exit regions (312A and 312B) which provide curved magnetic fields (312A, 312B), giving focusing or divergence of the beam of charged particles passing through the fringe field at an angle to the normal to the entry or exit region. The apparatus includes resolving means (332) for selecting a required species of particle from the beam by parameter dependent dispersion in a plane transverse to the reference surface (320), by focusing of the beam of particles at different focal points (331) along the general direction of propagation of the beam (314).

    Abstract: An apparatus which has the capability of filtering unwanted species from an extracted ion beam without the use of a mass analyzer magnet is disclosed. The apparatus includes an ion source having chamber walls that are biased by an RF voltage. The use of RF extraction causes ions to exit the ion source at different energies, where the energy of each ion species is related to its mass. The extracted ion beam can then be filtered using only electrostatic energy filters to eliminate the unwanted species. The electrostatic energy filter may act as a high pass filter, allowing ions having an energy above a certain threshold to reach the workpiece. Alternatively, the electrostatic energy filter may act as a low pass filter, allowing ions having an energy below a certain threshold to reach the workpiece. In another embodiment, the electrostatic energy filter operates as a bandpass filter.
