    摘要: The charged particle beam microscope is configured of: a gas field ionization ion source (1); a focusing lens (5) which accelerates and focuses ions that have been discharged from the ion source; a movable first aperture (6) which limits the ion beam that has passed through the focusing lens; a first deflector (35) which scans or aligns the ion beam that has passed through the first aperture; a second deflector (7) which deflects the ion beam that has passed through the first aperture; a second aperture (36) which limits the ion beam that has passed through the first aperture; an objective lens (8) which focuses, on a sample, the ion beam that has passed through the first aperture; and a means for measuring the signal, which is substantially proportional to the current of the ion beam that has passed through the second aperture.

    摘要: Provided are a large-current and highly stable gas field ionization ion source, and a high-resolution ion microscope with a large focal depth. The present invention relates to an ion microscope provided with a gas field ionization ion source, in which disposed are a refrigerator for cooling the gas field ionization ion source independent of the main body of the ion microscope, and a refrigerant circulation circuit cooling mechanism for circulating a refrigerant between the gas field ionization ion source and the refrigerator. Consequently it is possible to reduce the mechanical vibration of the refrigerator, which propagates to the gas field ionization ion source, and to achieve both the improvement of the brightness of the ion source and the improvement of ion beam focusing performance.
