It is built around a " focusing " bent crystal monochromator.
2.
Monochromaticity is achieved either with a crystal monochromator or a time of flight spectrometer.
3.
Some of the feasible crystal monochromator reflections and energy analyzer reflections have been tabulated.
4.
For those topography techniques requiring a monochromatic x-ray beam, an additional crystal monochromator is mandatory.
5.
A "'crystal monochromator "'is a device in X-ray optics to select a defined wavelength of the radiation for further purpose on a dedicated instrument or beamline.
