 || 10.10.2014 || '''Casey Deen''' || '''Alignment challenges and strategies for the GRAVITY wavefront sensor cryostat and tower[[BR]]'''[[BR]]Aligning a handful of small mirrors,filters, and lenses with a laser shouldn't be so difficult, right? Surely no more than an afternoon!  But after another week spent huddled in a dark laboratory, the light still does not end up in the correct position on the detector!  In order to avoid this frustrating situation, an alignment strategy is an important part of building any instrument. Casey Deen presents the alignment concept for the GRAVITY wavefront sensor. This near-infrared sensor works on the Shack-Hartman Principle. Due to their wavelength range, near-infrared sensors have a larger selection of bright guide stars than do optical sensors, as most stars are brightest in the infrared.  Optical light is also attenuated more by interstellar dust, making optical sensors impractical in dusty regions like the Galactic Center. The wavefront sensors are located in the Coude rooms of the Unit Telescopes of the Very Large Telescope (VLT). The location and the optical design of the wavefront sensors present several challenges for alignment. Casey and his colleagues present their strategy for alignment of the optics, and are looking forward to hearing opinions, advice and concerns from the assembled experts at MPIA. Expect a lively discussion and insight on what is laboratory work about! [[BR]][[BR]]Talk: English                  [[BR]]Slides: German[[BR]]Questions: German, English ||

PANIC is a panoramic imager. Klaus Meisenheimer will tell us more about its capabilities. He will also[[BR]]show that the tests in the laboratory demonstrated good image quality and high throughput. Currently, the instrument is on its way to the Calar Alto. After arrival it will be re-integrated and will see first light in beginning of November. In this presentation, we also hear what happened to PANIC in this most interesting phase of a project and learn what will be observed with this instrument to understand our universe better.[[BR]][[BR]]Talk: German                  [[BR]]Slides: English[[BR]]Questions: German, English ||

There have been different opinion between LBT Observatory and the consortium how the implementation should go on. Make up your own opinion if this is the right path.

 || 07.11.2014 || '''Roland Gredel''' || '''LUCI - it goes even sharper[[BR]][[BR]]'''Why became LUCIFER a girl? When does LUCI see with full sharpness? Actually, both twin near infrared spectrographs are already at the Large Binoculare Telescope for a while. Nevertheless, there is still some work to do and some parts of the instrument are still missing. Roland Gredel will update us about the last situation of the LUCI instruments. He will present exiting observation results of the last years and explain us how and when the instrument will reach its full capability. Running into trouble is not unusual building prototypes - as we do - and lessens learned from such a project are not only informative but also entertaining.[[BR]][[BR]]Talk: German                                          [[BR]]Slides: English                              [[BR]]Questions: German, English ||
