A contribution to characterizing and calibrating the pointing control system of the SOFIA telescope
(Univ. Stuttgart, 2009)SOFIA, the Stratospheric Observatory for Infrared Astronomy, is an airborne observatory that will study the universe in the infrared spectrum. A Boeing 747-SP aircraft will carry a 2.5 m telescope designed to make sensitive ... -
Broadband IF circuits for superconductor isolator superconductor (SIS) mixers for the Heterodyne Instrument for the far infrared on the Herschel Space Observatory and for sideband separating mixers
(Univ. Köln, 2007)This thesis describes the development and manufacturing of the IF circuits for two different heterodyne receivers used for sub-mm radio astronomy. The first project is the broadband 4-8 GHz IF circuitry for the mixer units ... -
Design and analysis of a broadband SIS-mixer for the Heterodyne Instrument for the Far Infrared (HIFI) on the Herschel Space Observatory
(Univ. Köln, 2006)In this thesis the design and analysis of SIS-mixers (SIS: superconductor-isolator-superconductor) for the use as low-noise and broad-band detectors in the submm-region for astronomical observations is described. The ... -
The LRS double prism assembly to be flown on the James Webb Space Telescope and host galaxies of active galactic nuclei in the near infrared
(Univ. Köln, 2008)The work presented in my thesis covers two aspects of modern astronomy: Observations and instrumentation. Part I of this thesis addresses the design, the development and the qualification of the Low Resolution Spectroscopy ...
