Recent Advances in Quantitative Convergent Beam Electron Diffraction
Two recent advances in quantitative convergent beam electron diffraction (CBED) developed at the University of Bristol are described in this paper. The first is a new scanning technique in which the diffracted intensities in the resulting pattern are integrated through the Bragg condition, equivalent to precessing the sample around a stationary beam. Many more reflections are excited than in a ...
متن کاملRecent Advances in Electron Momentum Spectroscopy *
The flexibility of the (e, 2e) technique or "electron momentum spectroscopy" (EMS) in obtaining information on the electronic structure of atoms, molecules, and solids is demonstrated. Highresolution EMS measurements for argon, including the first measurements of momentum profiles belonging to the 2 P° and D-manifolds, are used to demonstrate the technique for atomic targets. The d-wave transit...
متن کاملRecent Advances in Polarized Electron Sources*
Current experimental physics programs at a number of electron accelerator laboratories worldwide require the delivery of high average current highly polarized electron beams for long periods of time. The polarized electrons are produced by near bandgap photoemission from certain semiconductor photocathodes. We observe the quantum efficiency of these cathodes to be inversely related to the total...
متن کاملRecent Advances in Natural Language Processing
Recent developments in statistical machine translation (SMT), e.g., the availability of efficient implementations of integrated open-source toolkits like Moses, have made it possible to build a prototype system with decent translation quality for any language pair in a few days or even hours. This is so in theory. In practice, doing so requires having a large set of parallel sentence-aligned bi...
متن کاملRecent Advances in Energy Efficient Query Processing
Web search companies distribute their infrastructures and operations across several, geographically distant data centers. This distributed architecture facilitates high performance query processing, which is fundamental for the success of a Web search engine. At the same time, data centers require an huge amount of electricity to operate their computing resources. In this extended abstract, we ...
