Proceedings ArticleDOI
Prototyping of cryomechanisms for the JWST near-infrared spectrograph (NIRSpec)
Ralph Hofferbert,Dietrich Lemke,A. Böhm,Ulrich Grözinger,Thomas Henning,Armin Huber,Oliver Krause,Stefan Mertin,Jose Ramos,Ralf-Rainer Rohloff,Georg Luichtel,Kai Weidlich,Gilles Baudin,Winfried Posselt,Ruben Nalbandian,Peter Jensen +15 more
TL;DR: In this article, the authors give an overview on the detailed design, prototyping and testing of those mechanisms comprising highest reliability in the cryo-vacuum (~ 35K) combined with minimal power dissipation (~ 5mW on average), ultimate position accuracy (ARIANE 5, ~ 60g) and a very long lifetime (~ 15 years) for ground tests and space operation under various environmental conditions.
Journal ArticleDOI
The Earliest Phases of Star Formation (EPoS): A Herschel Key Program - The precursors to high-mass stars and clusters
Sarah Ragan,Thomas Henning,Oliver Krause,Jan Pitann,Henrik Beuther,Hendrik Linz,J. Tackenberg,Zoltan Balog,Martin Hennemann,Ralf Launhardt,N. Lippok,Markus Nielbock,Anika Schmiedeke,Anika Schmiedeke,Frederic Schuller,Juergen Steinacker,Amelia M. Stutz,Tatiana Vasyunina +17 more
TL;DR: In this paper, the spectral energy distributions (SEDs) of 496 cores were derived from single-temperature modified blackbody fits of the SEDs, derived the temperature, luminosity, and mass of each core.
Proceedings ArticleDOI
Transients in stressed Ge:Ga photoconductors under high background for PACS
Jutta Stegmaier,Stephan M. Birkmann,Ulrich Grözinger,Nancy M. Haegel,Dietrich Lemke,Oliver Krause +5 more
TL;DR: In this article, the authors measured transient responses of Ge:Ga photoconductors to a step change in the incident photon flux level as well as a test setup that allows creation of transients by different methods.
Proceedings ArticleDOI
Preparing Herschel's commissioning phase: Ge:Ga detector tuning
TL;DR: In this article, the photodetector array camera and spectrometer (Pacs) instrument aboard the Herschel space observatory was tested under space radiation environment during the commissioning phase (CP).
Proceedings ArticleDOI
A test setup for the characterization of far-infrared filters under cryogenic conditions
Stephan M. Birkmann,Ulrich Grözinger,Jutta Stegmaier,Oliver Krause,Eckhard Pitz,Dietrich Lemke +5 more
TL;DR: In this paper, the authors present a test platform that allows to measure the transmission of cold (T ~ 4K) filters in the far-infrared (FIR) using a dual grating monochromator with excellent spectral purity.
