Paper Abstract

On-stream performance of crystal diffraction components at synchrotron radiation facilities is certainly limited by the issues of heating and photochemistry discussed by other contributors to this conference. At the same time, the delivered performance is also limited by the quality of the starting material, strains and distortions introduced by the initial shaping and surface preparation, and by whatever re- forming operations (e.g. one and two dimensional stressing or bending) are needed to realize the desired x-ray optical function. Each of these issues, initial crystal quality, surface preparation, and final figure, can be assessed by rather simple arrangements using conventional x-ray diffraction tube sources in combination with appropriate beam conditioning elements and effective 2D imagers. These table-top arrangements represent a modest investment in comparison with realistic costs of beamline operation, but they are often neglected. An evident benefit of such off- line quality control is that on-line performance becomes predictable at least in the limit of low heating and radiation damage, so that the effects of these inevitable difficulties are more clearly isolated, thereby opening the way toward their effective management.
