Scanning x‐ray radiography: First tests in an electron spectrometer

摘要

The aim of this paper is to present the first images obtained in scanning x‐ray radiography without the help of synchrotron radiation but simply with a classical x‐ray source, that is, a scannable electron beam focused on an aluminum foil to produce characteristic x‐ray lines. The emitted x rays (about 1011–1012x‐ray photons s−1 mm−2) allow the observation of highly absorbing specimens in a nonabsorbing matrix about 10 mgr;m thick. We show that these results can be improved by simple modifications of a scanning transmission electron microscope.
