Abstract

High precision temperature measurements are a transversal need in a wide area of physical experiments. Space-borne gravitational wave detectors are a particularly challenging case, requiring both high precision and high stability in temperature measurement. In this contribution, we present a design able to reach 1 µK/Hz---v in most of the measuring band down to 1 mHz, and reaching 20 µK/Hz---v at 0.1 mHz. The scheme is based on resistive sensors in a Wheatstone bridge configuration which is AC modulated to minimize the 1/f noise. As a part of our study, we include the design of a test bench able to guarantee the high stability environment required for measurements. We show experimental results characterising both the test bench and the read-out, and discuss potential noise sources that may limit our measurement., Peer Reviewed, Postprint (published version)

Abstract

The Laser Ranging Interferometer (LRI) instrument on the Gravity Recovery and Climate Experiment (GRACE) Follow-On mission has provided the first laser interferometric range measurements between remote spacecraft, separated by approximately 220 km. Autonomous controls that lock the laser frequency to a cavity reference and establish the 5 degree of freedom two-way laser link between remote spacecraft succeeded on the first attempt. Active beam pointing based on differential wavefront sensing compensates spacecraft attitude fluctuations. The LRI has operated continuously without breaks in phase tracking for more than 50 days, and has shown biased range measurements similar to the primary ranging instrument based on microwaves, but with much less noise at a level of $1\,{\rm nm}/\sqrt{\rm Hz}$ at Fourier frequencies above 100 mHz.

Abstract

The Gravity Recovery and Climate Experiment (GRACE) is a joint US/German mission that has been mapping the Earth's gravity field since 2002 by measuring the distance variations between two spacecraft using a micro-wave link. GRACE is reaching the end of its lifetime. For this reason and in order to minimize data gaps, an almost identical mission will be launched in 2017. This mission is called GRACE-Follow On (GRACE-FO) and it will include an additional instrument as a technological demonstrator to monitor distance changes between the spacecraft. This instrument is the Laser Ranging Interferometer (LRI), which is based on heterodyne laser interferometry at 1064 nm and takes advantage of many technologies developed for LISA. In this paper a short overview of the current status of the German contribution is presented.

6. Nachhaltigkeit: ein kulturelles, bisher aber chancenloses Wirtschaftsziel

Author

Meyer-Abich, Klaus Michael and Meyer-Abich, Klaus Michael

Abstract

"In dem Gegensatz von 'schwacher' und 'starker' Nachhaltigkeit geht die schwache nicht weit genug zum Schutz der Natur, die 'starke' hingegen zu weit, weil sie der Wirtschaft unnötig scharfe Grenzen setzen würde. Sinnvoller wäre das positive Ziel, die Wirtschaft zu rekultivieren. Dem steht allerdings das Dreisäulentheorem der Gleichgewichtigkeit ökologischer, sozialer und ökonomischer Ziele entgegen. Hierzu wird eine radikale Anhebung der Erbschaftssteuer vorgeschlagen." (Autorenreferat), "'Weak sustainability' is as clear as economics but cannot sustain nature and would lead us into a world of swimming pools instead of beaches and fitness centres instead of walking paths. 'Strong sustainability', on the other hand, is too strong a limitation and politically weak because it sets limits instead of conceiving better goals such as re-cultivating the economy. Cultural sustainability is pointed out as a positive orientation. This, however, is not compatible with giving equal weight so ecological, social, and economic goals because capital is not aging. A solution can be found in radical increased inheritance taxes." (author's abstract)

8. Ist der Mensch etwas Besonderes in der Gemeinschaft der Natur? : das kleine und das größere Selbst

Author

Meyer-Abich, Klaus Michael and Meyer-Abich, Klaus Michael

Abstract

Die Industrieländer leben zu Lasten der Natur, zu Lasten der Dritten Welt und zu Lasten der Nachwelt. So geht es nicht weiter. Was statt dessen zu tun wäre, ist bekannt. Trotzdem geschieht es nicht. Es geschieht nicht, weil wir noch nicht verstanden haben, wie wir zur Gemeinschaft der Natur gehören. Wir halten uns sozusagen für etwas Besseres als die Natur, aber das sind wir nicht. Wir sind Mensch gewordene Natur und sind dem Ganzen der Natur schuldig, wofür wir gut sind.
