Monochromatic X-radiation

Abstract

Crystal-reflected X-radiation is becoming increasingly used for taking diffraction photographs because it eliminates the background due to the white radiation present in the direct beam from the X-ray tube. Various crystals can be used as reflectors and descriptions are given of some of them, together with a list of properties which determine their usefulness for different sorts of investigations In addition, a simple instrument for mounting a crystal is described; its main advantage is its compactness, which ensures that the reflected beam is as intense as possible.
