A Monte Carlo model was used to simulate specimen-electron beam interactions relevant electron back-scattered diffraction (EBSD). Electron trajectories were calculated for a variety of likely experimental conditions examine the interaction volume incident electrons as well that subset emerge from specimen, i.e., (BSEs). The spatial resolution EBSD investigated functions both materials properties, such atomic number, weight, and density, parameters, specimen thickness, tilt, accelerating...
In a busy world, continuing with the status-quo, to do things way we are already familiar, often seems be most efficient conduct our work. We look for value-add decide if investing in new method is worth effort. How shall evaluate have reached this tipping point change? For contemporary researchers, understanding properties of data good starting point. The generation neutron scattering instruments being built higher resolution and produce one or more orders magnitude larger than previous...
The primary mission of user facilities operated by Basic Energy Sciences under the Department is to produce data for users in support open science and basic research [1]. We trace back almost 30 years history across selected illustrating evolution facility management practices how these have related performing scientific research. cover multiple techniques such as X-ray neutron scattering, imaging tomography sciences. Over time, detector acquisition technologies dramatically increased...
Abstract The study of texture and grain boundary misorientation in multiphase materials has been greatly benefited from the recent automation electron back-scattered diffraction (EBSD) technique. With this technique, each phase a material can be individually sampled analyzed. This is great significance interest thin films, inclusions alloys. Spatial resolution, which depends on experimental conditions such as beam energy specimen tilt, being studied, critical order to determine orientation...
Abstract Whereas the spatial resolution for standard secondary electron (SEI) imaging in a scanning microscope or probe microanalyzer is related to incident diameter, x-ray microanalysis convolution of diameter with extent analyzed volume point probe. The latter determined by scattering specimen and subsequent emission excited x-rays from specimen. As such, it possible that “What you see not what get”. This especially true instruments high brightness sources (field emission). problem...
