  • Ion sources, systems and methods
    Patent number: 9029765
    Abstract: Ion sources, systems and methods are disclosed. In some embodiments, the ion sources, systems and methods can exhibit relatively little undesired vibration and/or can sufficiently dampen undesired vibration. This can enhance performance (e.g., increase reliability, stability and the like). In certain embodiments, the ion sources, systems and methods can enhance the ability to make tips having desired physical attributes (e.g., the number of atoms on the apex of the tip). This can enhance performance (e.g., increase reliability, stability and the like).

  • Charged particle source with light monitoring for tip temperature determination
    Patent number: 8993981
    Abstract: Systems and methods for heating an apex of a tip of a charged particle source are disclosed. The charged particle source can be, for example, a gas ion source. The systems can include a detector configured to detect light generated by the tip apex, and a controller coupled with the charged particle source and the detector so that the controller can control heating of the tip apex based on the light detected by the detector.

  • Systems and methods for a gas field ion microscope
    Patent number: 7601953
    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.
