Laboratory complex for the tests of the X-ray optics and coherence-related techniques

Abstract

The requirement for the high-quality optics for the 4^th generation synchrotrons is becoming particularly urgent nowadays. We present a laboratory complex “SynchrotronLike” designed for the X-ray optics tests and development of the X-ray optical techniques before their use on the synchrotron sources. This complex consists of four main parts: 1) microfocus Xray source MetalJet D2+ 70kV, 2) detector module that contains X-ray spectrometer and three X-ray cameras with different resolution and field of view, 3) Micro-Optics Test Bench for X-ray optics tests and development of the X-ray optical techniques, 4) X-ray Single Crystal Diagnostics Endstation for the X-ray diffraction microscopy experiments. This complex was successfully used for the preliminary tests of the X-ray refractive lenses made from polymer, epoxy, and diamond. Moreover, the ultracompact X-ray transfocators, diamond monochromators, and beam-splitters for the 4th generation synchrotron sources were also tested on the “SynchrotronLike”. The unique parameters of our laboratory source, such as high brightness and high beam coherency make it possible to implement versatile experimental synchrotron techniques. Consequently, we managed to get excellent results in the X-ray reflecto-interferometry and X-ray microradian diffraction. The results of the latter technique are presented in this paper.
