    摘要: Provided is an electrostatic lens for charged particle radiation with a lens performance relatively comparable to that of a magnetic type lens. A plurality of electrodes arranged on the incident side of charged particles form a first electric field area, wherein orbit radii of the charged particles are reduced without exceeding, on the way, the initial orbit radii that are orbit radii at the incident time, and a second electric field area, wherein force in the direction advancing in parallel with a central axis is applied to the charged particles that have passed through the first electric field area. A plurality of electrodes arranged on the projection side form a third electric field area, wherein the orbit radii of the charged particles do not exceed the initial orbit radii on the way and are curved to intersect with a central axis at angles larger than orbit angles defined with respect to the central axis of when the charged particles are projected from the second electric field area.

    摘要: An X-ray convergence element and an X-ray irradiation device including the X-ray convergence element are provided. The X-ray convergence element can extend a working distance from an exit-side opening end thereof to a specimen, and can perform analysis of the specimen with rough surface, a fluorescent X-ray analysis, and a X-ray diffraction analysis, regardless of a size of the specimen. An X-ray blocking member 23 is provided with three supporting members 233 for supporting the X-ray blocking member 23, which extend from an annular member 232 having approximately the same diameter as a diameter of an entrance-side opening end (outer diameter of a capillary 20) toward the center of the X-ray blocking member 23 to fix the annular member 232 to the capillary 20. The annular member 232, the supporting members 233, and the X-ray blocking member 23 are integrally formed of a metal that shields X-rays, such as tantalum, tungsten, or molybdenum. A dimension of the X-ray blocking member 23 in the axial direction (thickness) is set to be sufficient for blocking X-rays.

    摘要: An apparatus and method of identifying substances contained in a sample to both identify the elements in the sample and to measure a distribution of the elements are provided. The sample is scanned with electron beams to form X-ray images of two or elements. These X-ray images can be used to form a scattering diagram, and the composition of known materials can be plotted on the scattering diagram. The substances contained in the samples can be identified, and the distribution of the substances can be obtained by comparing the data on the scattering diagram with the plot.
