Paper Abstract

A versatile X-ray spectrometer/scatterometer for the study of X-ray optical elements such as grazing incidence mirrors, crystals and X-ray gratings has been built and put into operation at the Danish Space Research Institute. The spectrometer is built on a 1.5 m long granite bench with the X-ray source located at one end of the bench where it can be rotated around a fixed vertical axis. The beam defining elements are perfect crystals of Si, Ge or Quartz. With these it is possible to define a highly collimated beam of a few arcsec FWHM in the scattering plane. Examples of measurements on various X-ray optical elements are presented. In particular, a study of intrinsic and mosaic diffraction from test crystals is presented in detail. The deconvolution of the experimental data is discussed in general terms and as an example the results of a calculation of the spectrometer resolution function for the four crystal set-up employed in the above mentioned crystal study are presented.
