Approaches for Promoting Accurate Atom Probe Reconstruction
Comparison of atom probe tomography (APT) results from different instruments, different users, or different samples requires confidence in overall reconstruction accuracy. The conventional reconstruction algorithm utilizes a single point-projection onto a spherical surface [1,2]. Although there are a limited number of parameters used to prescribe how detector events are converted to a 3D set of...
متن کاملDynamic reconstruction for atom probe tomography.
Progress in the reconstruction for atom probe tomography has been limited since the first implementation of the protocol proposed by Bas et al. in 1995. This approach and those subsequently developed assume that the geometric parameters used to build the three-dimensional atom map are constant over the course of an analysis. Here, we test this assumption within the analyses of low-alloyed mater...
متن کاملAn Overview of Wide-Field-Of-View
While large aperture telescopes are highly desirable for their enormous light grasp, smaller telescopes are increasingly pressed into service as wide-field survey instruments to aid in the search for near earth objects, satellites and space debris. Various optical designs are found throughout the technical literature but not all represent truly capable wide-field survey instruments and the sear...
متن کاملWide field-of-view bifocal eyeglasses
When vision is affected simultaneously by presbyopia and myopia or hyperopia, a solution based on eyeglasses implies a surface with either segmented focal regions (e.g. bifocal lenses) or a progressive addition profile (PALs). However, both options have the drawback of reducing the field-of-view for each power position, which restricts the natural eye-head movements of the wearer. To avoid this...
متن کاملEffect of Field-evaporation Rate on Quantitative Atom-probe Analysis
The effects of field-evaporation rate on the quantitative chemical analysis of materials by atom-probe field-ion microscopy are considered. Examples of erroneously high measured values of the Ti concentration in Mo-1.0 at.% Ti and Mo-1.0 at.% Ti-0.08 at.% Zr (TZM) alloys are presented and the cause is shown to have been due to a high field-evaporation rate. The basic arguments used to explain t...
