When produced by dip coating, the self-organizing layers grow in a reproducible thickness of single or multiple molecule monolayers of a few nanometer thickness only. In this work, we introduce a method of determining the layer thickness of poly-dopamine on mirrors for astronomical X-ray telescopes. This work is based on spectroscopic ellipsometry measurements and involves the development of an optical model for the poly-dopamine layers including the dielectric function. Thereby the complex refractive index of the produced layers was determined, covering the range from the ultraviolet to the near infrared spectral region. These measurement results and the corresponding technical challenges are presented in this contribution. Furthermore, an outlook to potential technical applications of this interesting material is given and poly-dopamine layers will make scientist and engineers hopefully happy as an innovative and fascinating technical solution for the future.}, subject = {D{\"u}nne Schicht}, language = {en} } @book{SchneiderStoermann2024, author = {Schneider-St{\"o}rmann, Ludger}, title = {Konflikte und Verhandlungsmanagement im Vertrieb}, editor = {Schneider-St{\"o}rmann, Ludger}, publisher = {UVK Verlag}, address = {M{\"u}nchen}, isbn = {9783825262679}, pages = {258}, year = {2024}, abstract = {„Never give without taking" ist das Verhandlungsmotto von Ludger Schneider-St{\"o}rmann.

This instrument can generate a collimated X-ray beam up to 60 keV, even though the most interesting energy region for x-ray astronomy applications is usually below 10 keV. In the softest part of this range (below 6 keV), high X-ray absorption in air hinders a full and precise characterization of optical components. In this work, we present an upgrade of the Bede D1 diffractometer that extends the operative range of the instrument below 6 keV; this is done by maximizing the flux at lowest energies and by reducing absorption by means of a helium-rich atmosphere. The upgraded instrument will be used for the tests of X-ray mirrors with innovative soft X-ray coatings, with potential application to the next generation X-ray telescopes (such as ATHENA and eXTP).}, subject = {R{\"o}ntgenspiegel}, language = {en} } @inproceedings{StanikPreglerDoehringetal.2025, author = {Stanik, Eva and Pregler, Jan and D{\"o}hring, Thorsten and K{\"a}tker, Anna and Busch, Uwe and Friedrich, Peter}, title = {A visitor experiment on astronomical x-ray optics for the "Deutsches R{\"o}ntgenmuseum"}, series = {EUV and X-ray Optics: Synergy between Laboratory and Space IX}, volume = {2025}, booktitle = {EUV and X-ray Optics: Synergy between Laboratory and Space IX}, number = {13531}, editor = {Hudec, Ren{\´e} and Pina, Ladislav}, publisher = {SPIE}, doi = {10.1117/12.3056291}, pages = {135310M-1 -- 135310M-7}, year = {2025}, abstract = {The "Deutsches R{\"o}ntgen-Museum" in Remscheid (Germany) is the unique institution worldwide that researches and documents the life and work of the first Nobel Prize winner in physics, Wilhelm Conrad R{\"o}ntgen, and the effects of his discovery of X-rays.
