'''__Time__: Always Mondays 15:00 - 16:00''' '''Location: MPIA Hoersaal ''' '''Outline:''' * Announcements (news, visitors, etc.) (mainly in German) * Talk of about 30 min about a selected topic (German or English, will be announced) * Follow up discussion and questions (German or English, depending on the speaker) [[BR]]Proposals for talks: Please send an email to "huber -at- mpia.de" or "naranjo -at- mpia.de" - alternatively you might reach us by phone (06221-528331 or -290) or in person (room 111 or 018) at MPIA. ||'''Date''' ||'''Speaker ''' ||'''Topic''' || || '''16.09.2024''' || '''Werner Laun''' || '''The METIS-cryostat'''[[BR]][[BR]]The new large ELT telescope is slowly growing on the Cerro Armazones in Chile. At the same time as the telescope is being built, the first generation of instruments is also being built. The MPIA is involved in 2 instruments, METIS and MICADO. For METIS, the MPIA has taken on two large work packages: the wavefront sensor and the imager. The design and construction of the cryostat, which is the subject here, are work packages of ETH Zurich. However, the MPIA was heavily involved in the initial concept and design. In the meantime, the first parts of the cryostat have arrived in Zurich and integration has begun.[[BR]][[BR]]This talk is intended to explain what a cryostat is and how this special cryostat for METIS is constructed. Colleagues who are not involved in instrumentation or science are also invited to attend.[[BR]][[BR]][[BR]]Presentation: German[[BR]][https://svn.mpia.de/trac/att/raw-attachment/wiki/WikiStart/AstroTechTalk_Metis_cryostat_16_09_2024.pdf Slides: English][[BR]]Questions: German, English || || 30.09.2024 || || || || 14.10.2024 || || || || 28.10.2024 || || || || '''11.11.2024''' || '''Julian Stuermer (LSW)''' || '''CUBES'''[[BR]][[BR]]CUBES, the Cassegrain U-Band Efficient Spectrograph, brings a unique capability to ESO’s Very Large Telescope:  an ultraviolet eye on the Universe to complement the Extremely Large Telescope. CUBES aims to be the most efficient (> 40%) ground based spectrograph in the UV with a spectral coverage of 300–405 nm. Two resolution modes are offered: 20000 and 7000. [[BR]] [[BR]]The final design phase is currently being completed and it is expected that manufacturing phase is starting early next year. [[BR]] [[BR]]The talk gives an overview of CUBES, with a focus of the technical challenges in optics and mechanics. New grating technology enables high efficiency in the UV, while an active flexure compensation supports the spectral stability of the instrument.[[BR]][[BR]]Presentation: German[[BR]]Slides: English[[BR]]Questions: German, English || || '''14.11.2024''' || '''Cécile Deprez (DLR Munich)''' || '''The Future of Satellite Navigation'''[[BR]][[BR]]At the German Aerospace Center (DLR), we are pioneering the next generation of satellite-based positioning systems. Our research focuses on integrating innovative technologies, including laser communication links and optical clocks, into satellite payloads to significantly enhance positioning accuracy for ground and space users. [[BR]][[BR]]In this lecture, we will introduce the key concepts of satellite-based positioning and present the solutions developed at DLR for the future of global navigation.[[BR]][[BR]]Presentation: English[[BR]]Slides: English[[BR]]Questions: German, English || || 25.11.2024 || || || || 09.12.2024 || || || '''Preview:''' DD.MM.2024 - Speaker: Title 11.11.2024 - Julian Stuermer (LSW): TBD '''Postview:''' [wiki:OldPresentations2014S2 Presentations from 12.09. - 31.12.2014] [wiki:OldPresentations2015S1 Presentations from 01.01. - 31.07.2015] [wiki:OldPresentations2015S2 Presentations from 01.08. - 31.12.2015] [wiki:OldPresentations2016S1 Presentations from 01.01. - 31.07.2016] [wiki:OldPresentations2016S2 Presentations from 01.08. - 31.12.2016] [wiki:OldPresentations2017S1 Presentations from 01.01. - 31.07.2017] [wiki:OldPresentations2017S2 Presentations from 01.08. - 31.12.2017] [wiki:OldPresentations2018S1 Presentations from 01.01. - 31.07.2018] [wiki:OldPresentations2018S2 Presentations from 01.08. - 31.12.2018] [wiki:OldPresentations2019S1 Presentations from 01.01. - 31.07.2019] [wiki:OldPresentations2019S2 Presentations from 01.08. - 31.12.2019] [wiki:OldPresentations2020S1 Presentations from 01.01. - 31.07.2020] [wiki:OldPresentations2020S2 Presentations from 01.08. - 31.12.2020] [wiki:OldPresentations2021S1 Presentations 2021S1] [wiki:OldPresentations2022S1 Presentations 2022S1] [wiki:OldPresentations2022S2 Presentations 2022S2] [wiki:OldPresentations2023S1 Presentations 2023]
