Paper Abstract

We present recent developments in the production of X-ray multilayer optics for Cu Kα laboratory single crystal diffraction equipment for protein crystallography and structural proteomics. The paper shows design, simulations and properties of Montel optics comprised of two elliptically bent focusing multilayers, optimized for the use with modern rotating anode X-ray generators. The multilayers are sputter deposited with a graded d-spacing along the length of the substrate. The various beam properties such as flux density and divergence are investigated in detail. After optimization of the optic for a state-of-the-art rotating anode x-ray generator, we obtain a flux density of 1 x 1010 photons/s/mm2. Results for a typical protein structure will be shown, illustrating the advantage of Montel optics in the field of single-crystal diffraction and protein crystallography for life sciences.
