Notes:
Monochromator crystal heating and radiation damage may be reduced significantly by reflecting much of the incident radiated power from the surface of the crystal. This requires strong Bragg diffraction of the monochromatized beam at grazing incidence angles. Examples of such cases are described, such as extremely asymmetric diffraction and grazing angle diffraction, which would permit continuously tunable x-ray energy. Additional benefits such as increased angular acceptance, variable beam cross section, adjustable bandpass, and increased flux for self-filtering monochromators are presented, and various considerations in implementation are discussed. Finally, the possibilities for exploiting the unused reflected x rays will be explored.
