    Abstract: Provided is a multifunctional charged particle beam device capable of inclining a beam with little aberration. The aberration is corrected by forming a local divergent field with a multipole, parallel current lines, or the like, matching the beam axis with the local divergent field via a conventional rotationally symmetric lens, deflector or astigmatism corrector, and counteracting an aberration occurring from another rotationally symmetric convex lens field.

    Abstract: The present invention relates to a lens-less Foucault method wherein a transmission electron microscope objective lens (5) is turned off, an electron beam crossover (11, 13) is matched with a selected area aperture (65), and the focal distance of a first imaging lens (61) can be changed to enable switching between a sample image observation mode and a sample diffraction pattern observation mode, characterized in that a deflector (81) is disposed in a stage following the first imaging lens (61), and conditions for an irradiating optical system (4) can be fixed after conditions for the imaging optical system have been determined. This allows a lens-less Foucault method to be implemented in a common general-use transmission electron microscope with no magnetic shielding lens equipped, without burdening the operator.

    Abstract: A multipole lens (100) which can produce static magnetic fields showing different strengths in the direction of travel of an electron beam has lens subasssemblies (10a, 10b, 10c) stacked on top of each other. The lens subassemblies (10a, 10b, 10c) have yokes (14a, 14b, 14c), respectively, and polar elements (12a, 12b, 12c), respectively. The polar elements (12a, 12b, 12c) have base portions (13a, 13b, 13c), respectively, magnetically coupled to the yokes (14a, 14b, 14c), respectively, and front end portions (11a, 11b, 11c), respectively, magnetically coupled to the base portions (13a, 13b, 13c), respectively. Magnetic field separators (20, 22) made of a nonmagnetic material are mounted between the front end portions (11a, 11b, 11c) which are successively adjacent to each other in the direction of stacking of the lens subassemblies (10a, 10b, 10c).

    Abstract: A combined round-multipole magnetic lens comprises a coil bracket, a first pole piece and a second pole piece. At least a first pole shoe of the first pole piece on the coil support and at least a second pole shoe of the second pole piece under the coil support respectively extend towards the central axis. The first pole shoe and the second pole shoe are symmetric according to the central axis, or the first pole shoes and the second pole shoes are respectively symmetrically arranged, and the angle difference between the first pole shoe and the adjacent second pole shoes is 360/2N degrees. A magnetic circuit gap is formed between the first pole shoe and the adjacent second pole shoe, for generating a magnetic field distribution of multi-poles and reducing the volume and the number of power supplies.

    Abstract: The charged particle beam application device is provided with a charged particle source and an objective lens that converges charged particle beam generated by the charged particle source onto a sample. In this case, the charged particle beam application device is further provided with an aberration generating element installed between the charged particle beam source and the objective lens, a tilt-use deflector installed between the aberration generating element and the objective lens, a deflection aberration control unit for controlling the aberration generating element, a first electromagnetic field superposing multipole installed between the aberration generating element and the objective lens, and an electromagnetic field superposing multipole control unit for controlling the first electromagnetic field superposing multipole. The aberration generating element has such a function that when the charged particle beam is tilted relative to the sample by the tilt-use deflector, a plurality of resulting aberrations are cancelled with one another. Moreover, the first electromagnetic field superposing multipole has a function to change the orbit of a charged particle beam having energy different from that of the main charged particle beam in the charged particle beam.
