    2828|| '''22.01.2016''' || '''Ralph Hofferbert''' || '''On the way to the stars: Shipping of LINC-NIRVANA to the LBT[[BR]]'''[[BR]]As already written on our Christmas card:[[BR]]Wintry mood prevailed in November 2015 on top of Mount Graham, Arizona, at the Large Binocular Telescope (LBT): After more than ten years of planning, manufacturing and testing, LINC-NIRVANA found its ultimate mounting pad between the two primary mirrors of the LBT for the first time. The near infrared imaging instrument shall combine – depending on the implementation phase – adaptive optics and interferometric beam combination of the two mirrors to achieve ultra high spatial resolution. [[BR]][[BR]]Beforehand, the instrument had been disassembled und made a 6-week-trip over the Atlantic as one oversize transport plus nine sea containers. In the months to come the delicate optical components and the cryogenic near-infrared camera will be re-integrated, such that  LINC-NIRVANA and the telescope get finally married from mid of 2016 on.[[BR]][[BR]]The talk will mainly address the aspects related to the shipping and the initial installation at LBT. Besides that, the prime features of the instrument itself and the planned activities for 2016 will be briefely desribed.[[BR]][[BR]]Presentation: German                  [[BR]][https://svn.mpia.de/trac/gulli/att/raw-attachment/wiki/AlteVortraege2016S1/2015-09-18_Wie_gross.pdf Slides: German][[BR]]Questions: German, English ||

Design and development of those cryostats is one of MPIA's major work packages for MATISSE. [[BR]][[BR]]Various boundary conditions, contraints and interfaces require a specific and custom-made realisation. The talk tries describing in a vivid and  generally understandable way how the technological challenges have been solved.[[BR]][[BR]]Presentation: German                  [[BR]][https://svn.mpia.de/trac/gulli/att/raw-attachment/wiki/AlteVortraege2016S1/2015-09-18_Wie_gross.pdf Slides: Englisch][[BR]]Questions: German, English ||
