  • Systems and methods for a gas field ion microscope
    Publication number: 20070215802
    Abstract: In one aspect the invention provides a gas field ion microscope that includes an ion source in connection with an optical column, such that an ion beam generated at the ion source travels through the optical column and impinges on a sample. The ion source includes an emitter having a width that tapers to a tip comprising a few atoms. In other aspects, the invention provides methods for using the ion microscope to analyze samples and enhancing the performance of a gas field ion source.

  • Ion source method and apparatus
    Patent number: 5034612
    Abstract: Ion source methods and apparatus include an ion generating element for providing a reservoir of flowing liquid source material, accelerating elements for providing an electric field around the ion generating element, and shielding elements. The shielding element is constructed from a material including atoms which, if backsputtered onto the ion generating element, do not substantially degrade ion source performance.
