    摘要: An electron microscope comprising a microscope chamber having an aperture plate control mechanism mounted thereon and including an aperture support arm extending into the microscope chamber and mounted for movement along a longitudinal axis of said arm, and an aperture plate having at least one aperture, or passage, extending therethrough and being pivotably mounted on the support arm. First and second drive means are coupled to the support arm and the aperture plate, respectively, for varying the position of the aperture plate with respect to a beam of electrons.

    摘要: A workpiece mounting system comprising a chuck and a base is disclosed. The emissivity of the base is increased to allow more heat transfer from the chuck to the base. In some embodiments, the emissivity of the base may be controllable so that for ion beams with lower power levels, the emissivity remains low, enabling the chuck to reach the desired temperature quickly. For ion beams with higher power levels, the emissivity may increase to allow more heat transfer to the base, allowing the chuck to maintain the desired temperature. High emissivity coatings may be applied to the top surface of the base. In other embodiments, a set of movable shields may be disposed between the chuck and the base. The position of the shields may be a function of the power level of the incoming ion beam.
