Internally cooled X–ray optics, like X–ray monochromators and reflecting X–ray mirrors play a crucial role in defining a beamlines resolution, degree of coherence and flux. A great effort is invested in the development of these optical components. An important aspect of the functionality of high heat load optics is its cooling and its influence on surface deformation. The authors present a study of two different geometrical cooling approaches. It’s influence on beam inhomogeneity due to the strain from the manufacturing process is presented. X–ray topographic images and FWHM measurements are presented. FEA simulations of cooling efficiency and surface deformations was performed. The best achieved results are under an enlargement of 0.4 microrad of the measured rocking curve.
