Abstract

The first successful tests of a graded crystal x-ray monochromator at BESSY II based on SiGe crystals are reported. The monochromator crystals with Ge concentration gradient of 0.8%/cm along the crystal surface have been tested at the KMC- 2 beamline. The beam from the BESSY II bending magnet with vertical divergence of 0.2 mrad was used. In comparison with conventional Si crystals the enhancement of an energy resolution is 3 - 5 times and, simultaneously, increase of spectral flux density of 4 - 6 times were obtained.
