One of the numerous events that have been supported thereby has been that of the project "Zirkus UNI-versum" (in English: "Circus UNI-verse"), which took place in summer 2023 at Aschaffenburg University of Applied Sciences. Two school classes from the local high school "Kronberg-Gymnasium" first experienced an interactive astronomy lecture including a planetarium star show in a tent. Another highlight was the rocket car race in front of the cafeteria and the exclusive launch of a water rocket on the campus green. After the collective countdown, it reached a height of around eighty meters and thus rose higher than all the trees and buildings on the campus site. For their own exploration of the night sky the pupils obtained small cardboard star maps to assemble themselves as a homework. On the summer evenings of the following school holidays, they certainly observed the sky with a different point of view and, above all, with expert knowledge. The event has given them interesting impressions of Aschaffenburg Technical University as an attractive local education facility. The project "Zirkus UNI-versum" - and other activities for schools - intend to stimulate the interest of pupils in STEM subjects and to attract future engineering students.}, subject = {Astronomie}, language = {en} } @inproceedings{StanikDoehringPregleretal.2024, author = {Stanik, Eva and D{\"o}hring, Thorsten and Pregler, Jan 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}ntgen-Museum"}, series = {AXRO 2024 - 15th International Conference on Astronomical X-Ray Optics}, volume = {2024}, booktitle = {AXRO 2024 - 15th International Conference on Astronomical X-Ray Optics}, organization = {TH Aschaffenburg}, pages = {1 -- 1}, year = {2024}, abstract = {The "Deutsches R{\"o}ntgenmuseum" in Remscheid is the unique institution worldwide that researches and documents the life and work of the first Nobel Prize winner, Wilhelm Conrad R{\"o}ntgen, and the effects of his discovery of X-rays.

As part of a joint development project, students from Aschaffenburg University of Applied Sciences are currently designing a visitor experiment on astronomical X-ray optics for the museum laboratory. An optical set-up with visible light illustrate the focusing principle of X-ray telescopes, e.g. for wide-angle optics based on the lobster-eye principle. Display boards explain the optics of various types of telescopes with accompanying text and corresponding illustrations. Modern X-ray observatories such as CHANDRA, XMM-Newton and eROSITA are presented clearly.

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} } @misc{StanikDoehringPregleretal.2024, author = {Stanik, Eva and D{\"o}hring, Thorsten and Pregler, Jan and K{\"a}tker, Anna and Busch, Uwe and Friedrich, Peter}, title = {Ein Besucherexperiment zur astronomischen R{\"o}ntgenoptik f{\"u}r das Deutsche R{\"o}ntgen-Museum}, series = {DGaO Proceedings}, volume = {2024}, journal = {DGaO Proceedings}, number = {125}, publisher = {DGaO}, organization = {Technische Hochschule Aschaffenburg}, pages = {1 -- 1}, year = {2024}, abstract = {Das Deutsche R{\"o}ntgen-Museum in Remscheid ist eine weltweit einzigartige Institution, die das Leben und Werk des ersten Nobelpreistr{\"a}gers Wilhelm Conrad R{\"o}ntgen und die Auswirkungen seiner Entdeckung der R{\"o}ntgenstrahlung erforscht und dokumentiert.
