The trick is to make use of the total reflection from the thin low-density material (which does not suffer much the photoelectric absorption) at low X-ray energies; the reflection of photons at higher energies (< 4 keV) occurs thanks to the much denser material under the overcoating. For several future projects, like e.g. ATHENA, LYNX and eXTP, it is foreseen the use of low-density overcoatings that will importantly increase the effective area at low X-ray energies. In this paper we will introduce the use of overcoatings based on materials different from the usual ones considered so far like C, B4C and SiC. In particular, we will discuss about a novel approach based on the use of thin layer of a Carbon-like materials deposited using a dip coating method. A possible combination with an intermediate thin layer of Chromium deposited e.g. via sputtering onto the usual high density material (Ir, Au or Pt) before the application of the Carbon-like material is also considered in the study, because it can further greatly enhance the soft X-ray effective area of future X-ray telescopes.}, subject = {R{\"o}ntgenteleskop}, language = {en} } @article{KrausseSchneiderStoermannDoehring2019, author = {Krauße, Sylvana and Schneider-St{\"o}rmann, Ludger and D{\"o}hring, Thorsten}, title = {ITV- international studieren in Aschaffenburg}, series = {Die Neue Hochschule}, volume = {2019}, journal = {Die Neue Hochschule}, number = {6}, pages = {16 -- 19}, year = {2019}, abstract = {Die Wettbewerbsf{\"a}higkeit der Exportnation Deutschland erfordert hervorragend ausgebildete Vertriebsingenieurinnen und -ingenieure.
