Large aperture X-ray diffraction photograph production from reflex system

摘要

The apparatus for the production of X-ray diffraction photographs has an exciting electron beam between the objective lens of an electron gun and the sample. The beam is deflected magnetically or electrostatically so that the effective beam outlet cone, or opening angle, is considerably enlarged for the diffraction reflection. The electron beam is deflected magnetically using a coil system. The electron beam is deflected by a bent tube, which is electrostatically charged with negative polarity. The electron beam is deflected by a negatively charged electric mirror, or a negatively or a positively charged electrode.
