    摘要: In one aspect the invention provides a gas field ion source assembly 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. The ion source includes an emitter having a width that tapers to a tip comprising a few atoms. In other aspects, the methods provide for manufacturing, maintaining and enhancing the performance of a gas field ion source including sharpening the tip of the ion source in situ.
