Consequently new technical approaches for X-ray mirror production are under development. In Europe the technical baseline for the planned X-ray observatory ATHENA is the radical new approach of silicon pore optics. NASA´s recently launched NuSTAR mission uses segmented mirrors shells made from thin bended glasses, successfully demonstrating the feasibility of the glass forming technology for X-ray mirrors. For risk mitigation also in Europe the hot slumping of thin glasses is being developed as an alternative technology for lightweight X-ray telescopes. The high precision mirror manufacturing requires challenging technical developments; several design trades and trend-setting decisions need to be made and are discussed within this paper. Some new technical and economic aspects of the intended glass mirror serial production are also studied within the recently started interdisciplinary project INTRAAST, an acronym for "industry transfer of astronomical mirror technologies". The goal of the project, embedded in a cooperation of the Max-Planck-Institute for extraterrestrial Physics and the University of Applied Sciences Aschaffenburg, is to master the challenge of producing thin mirror shells for future X-ray telescopes. As a first project task the development of low stress coatings for thin glass mirror substrates have been started, the corresponding technical approach and first results are presented.}, subject = {Astronomie}, language = {en} } @inproceedings{WinterBreunigFriedrichetal.2015, author = {Winter, Anita and Breunig, Elias and Friedrich, Peter and Proserpio, Laura and D{\"o}hring, Thorsten}, title = {Indirect glass slumping for future X-ray missions: overview, status and progress}, series = {Proceedings of SPIE}, volume = {2015}, booktitle = {Proceedings of SPIE}, number = {9603}, organization = {Max-Planck-Institut f{\"u}r extraterrestrische Physik}, pages = {960308-1 -- 960308-8}, year = {2015}, abstract = {Future X-ray telescopes aim for large effective area within the given mass limits of the launcher.

This paper presents the status and progress of the indirect glass slumping technology developed at the Max-Planck-Institut for extraterrestrial Physics (MPE). Recent developments in our research include the use of the mould material Cesic under vacuum, as well as the fabrication of a high-precision slumping mould, which meets the requirements of large, high angular resolution missions like ATHENA. We describe the way forward to optimise the slumping process on these materials, the force-free integration concept and its progress, as well as the first test on reflective coating application.}, subject = {Astronomie}, language = {en} } @inproceedings{DoehringStollenwerkProserpioetal.2016, author = {D{\"o}hring, Thorsten and Stollenwerk, Manfred and Proserpio, Laura and Breunig, Elias and Friedrich, Peter}, title = {The challenging development of lightweight glass mirrors for future X-ray telescopes}, series = {DGaO Proceedings}, volume = {2016}, booktitle = {DGaO Proceedings}, publisher = {Deutsche Gesellschaft f{\"u}r angewandte Optik}, address = {Erlangen}, organization = {Hochschule Aschaffenburg}, issn = {1614-8436}, url = {http://nbn-resolving.de/nbn:de:0287-2016-B018-0}, pages = {2}, year = {2016}, abstract = {Previously used mirror technologies are not able to fulfill the challenging requirements of future X-ray telescopes.

In particular, the indirect slumping technology under investigation at the Max Planck Institute for Extraterrestrial Physics (MPE) is reviewed and recent activities are presented together with the research approach. The glass slumping technique foresees several steps: a thermal forming process using a suitable mould; a re ective layer application; the alignment and integration of mirror segments into a supporting structure; and the � nal veri� cation of prototype modules using X-rays. Each step is considered at MPE, with the involvement of partner institutes and universities. The last year of activities was mainly dedicated to the procurement of new moulds and to the application of Iridium coating.
