摘要： The present invention relates to atom probe evaporation processes. For example, certain aspects are directed toward methods for controlling an evaporation process in an atom probe that includes initiating the atom probe evaporation process and monitoring a parameter associated with material being evaporated from a specimen. The method can further include controlling at least one characteristic of the atom probe evaporation process to attain a desired evaporation rate or characteristic. In selected embodiments, monitoring a parameter associated with material being evaporated can include monitoring an evaporation rate, mass-to- charge ratios of evaporated ions, a mass resolution, a composition of material being evaporated, and/or the like. In certain embodiments, controlling at least one characteristic can include controlling a pulse energy, a pulse frequency, a bias energy, and/or the like. In other embodiments, various portions of the above process can be computer implemented.

摘要： In specimen atom probe (300) in a mass spectrometer (302) includes a voltage pulse (312) applied to the (300) and a first counter electrode (310) for producing a field ionizing pulse evaporation of ions (308) from the specimen (300); and the evaporated ions (308) subjected to corrective pulses which are synchronized with the ionizing pulses. These corrective pulses have a magnitude and timing sufficient to reduce the velocity distribution of the evaporated ions (308) for increasing mass resolution for the mass spectrometer (302) and are supplied from a second counter electrode (314) which is coupled to the first electrode (310) via an active network (322).
