TY - JOUR A1 - Döhring, Thorsten A1 - Hudec, Rene ED - Skopal, Augustín T1 - JEUMICO and TRILAMICO: Dimensions of successful Bavarian-Czech cooperation JF - Contributions of the Astronomical Observatory Skalnaté Pleso N2 - In December 2017 the two projects JEUMICO (an acronym for Joint European Mirror Cooperation) and TRILAMICO (standing for Trilateral Mirror Collaboration) are ending. Different aspects of this Bavarian-Czech collaboration between Aschaffenburg University and the Czech Technical University in Prague are discussed. The multiple dimensions of this cooperation are scientific achievements, public relation measures, internationalization of education, financial aspects, inter-cultural communication, and also the actual political situation within Europe.

Simulations of the use of different overcoats were performed in order to improve the reflectivity of thin iridium coatings designed for X-ray optics effective in the energy up to 10 keV. Samples based on these simulations were prepared and are being tested for the properties that influence the X-ray optical performance, such as layer homogeneity, density and surface micro-roughness. Further the topic of the coating stress was addressed, as it is an issue in case of thin, lightweight X-ray mirrors and affects the time stability of layers. The discussion and preliminary results conclude our contribution.

Thereby we show and discuss some experimental results and correlate them with simulations. Preliminary results of an ongoing study on other strange animal mirror eyes with potential scientific and technical applications are also discussed. Some of them are based on the principle of multilayer multi-mirror active optics arrangements. The Lobster Eye X-ray optics needs special reflective coatings for a better performance, which are currently developed within the Bavarian-Czech cooperation project JEUMICO.

Corresponding mirror segments use substrates of at silicon wafers which are coated with thin iridium � lms, as this material is promising high re ectivity in the X-ray range of interest. The sputtering parameters are optimized in the context of the expected re ectivity of the coated X-ray mirrors. In near future measurements of the assembled mirror modules optical performances are planned at an X-ray test facility.
