 || '''27.02.2015''' || '''Sascha Douffet''' || '''Occupational safety at MPIA'''[[BR]][[BR]]What is occupational safety ? Why do we need it at MPIA ?  Who "implements" it ? What is an ASA-meeting ? BG ?  Labour inspectorate ?[[BR]][[BR]]Every one of us has heard about it, some of us even have dedicated tasks in security-relevant fields at MPIA. But what is relevant for the rest of our colleagues in terms of training and instructions which aim to avoid any illegal practice.[[BR]][[BR]]Sascha Douffet will explain to us, how this complex field is organized at MPIA and MPG-wide, and how he became a trained employee for occupational safety. Furthermore, aspects like responsibility as individual person and in the team, established tools like ASIP for monitoring, available documentation and the importance of instructions will be discussed.

Aboard it will  have four scientific instruments: two of them - MIRI and NIRSpec - being  European deliveries with contributions from MPIA. MIRI has been built by  a European science consortium involving more than a dozen scientific  institutes - among them MPIA. [[BR]][[BR]]MIRI includes an imager and two spectrometers capable of doing imaging,  coronography as well as spectroscopy. MPIA has been responsible for the filter wheel and the two  dichroic-grating wheel mechanisms of the instrument. They have been  designed, partly manufactured and tested at MPIA with great involvements  of the design engineering department, the mechanical and the electronics workshops, respectively. The  scientific performance has been tested extensively in 2011 in the UK by  the MIRI test team.[[BR]] [[BR]]MIRI has been delivered to NASA in 2012, since then the test team is  supporting the cryo-test campaigns at the Goddard Space Flight Center,  is preparing the calibration pipeline and science cases. The talk will give an overview of MIRI's history at MPIA, its  scientific performance and the future till the launch in 2018.

 || '''20.03.2015''' || '''Michael Lehmitz''' || '''PLC control for MATISSE'''[[BR]][[BR]]Before the use of PLCs ("Programmable Logic Controllers") control tasks for scientific instruments were usually implemented with the help of discrete contact switches, relays and other electro-mechanical components in conjunction with a complex wiring. With increasing complexity of the scientific instruments and their infratructure also the demands with respect to the required control systems and their flexibility have grown.[[BR]][[BR]]For MATISSE, the "Multi-!AperTure mid-Infrared !SpectroScopic  Experiment" for the Very Large Telescope, MPIA applied for the first time PLCs for supervising the instrument's two cryogenic systems, for controlling its calibration light sources and for reading-out sensors on the optical bench.  [[BR]][[BR]]In this talk Michael Lehmitz gives an introduction to PLC-based control technology and presents, via a live-demo, the performance of the MATISSE system.[[BR]][[BR]]Talk: German[[BR]]Slides: English[[BR]]Questions: German, English ||
