AIRBUS APWORKS, a 100% subsidiary of Airbus Defence &  Space from Munich will present their competencies in this field of  manufacturing and will explain the advantages and disadvantages  of the SLM process (Selective Laser Melting) with the help of numerous  parts - mainly from Aerospace projects. Additionally, typical metal  materials for 3D printing will be presented, including the high strength  aluminum alloy Scalmalloy®, which was specifically  developed for additive manufacturing and which shows excellent  properties for Aerospace applications (high yield strength, low CTE, …).[[BR]][[BR]]Information about the presenter:[[BR]]* Born in Heidelberg[[BR]] * Aerospace Engineering Studies at the University of Stuttgart and at Virginia Tech, USA[[BR]] * Dissertation at Airbus Group Innovations, the research centre of Airbus (supervised by TU Darmstadt)[[BR]] * Focal Point for all Aerospace customers at AIRBUS APWORKS[[BR]][[BR]]Presentation: German[[BR]][https://svn.mpia.de/trac/gulli/att/raw-attachment/wiki/AlteVortraege2017S1/2017-05-19_3DDruck.pdf Slides: English][[BR]]Questions: German, English ||

GCT’s  dual-mirror Schwarzschild-Couder (SC) optical system allows the use of a  compact camera with small form-factor photosensors. [[BR]][[BR]]The GCT camera is ∼  0.4 m in diameter and has 2048 pixels; each pixel has a ∼ 0.2 angular  size, resulting in a wide field-of-view. The design of the GCT camera is  high performance at low cost, with the camera housing 32 front-end  electronics modules providing full waveform information for all of the  camera’s 2048 pixels. The first GCT camera prototype, CHEC-M, was  commissioned during 2015, culminating in the first Cherenkov images  recorded by a SC telescope and the first light of a CTA prototype. [[BR]][[BR]]In this talk, Justus Zorn will present results from CHEC-M from both lab measurements and  on-telescope operations. Furthermore, he will discuss first results from  CHEC-S, the second GCT-prototype based on a silicon photomultiplier.[[BR]][[BR]]Presentation: German[[BR]][https://svn.mpia.de/trac/gulli/att/raw-attachment/wiki/AlteVortraege2017S1/2017-06-02_CHECM.pdf Slides: English][[BR]]Questions: German, English ||
