Bestrahlungsinduzierte Modifikation der Materialparameter in magnesiumdotiertem Lithiumniobat
(2010-12-01)
Lithiumniobat-Kristalle sind von großem Interesse für das Forschungsfeld der optischen Datenübertragung. Durch eine Reihe interessanter Materialeigenschaften sind sie Grundlage für eine Vielzahl an Anwendungen in Wissenschaft, ...
Sensitivity of ATLAS to Alternative Mechanisms of Electroweak Symmetry Breaking in Vector Boson Scattering qq → qqlνlν
(2010-12-02)
An analysis of the expected sensitivity of the ATLAS experiment at the Large Hadron Collider at CERN to alternative mechanisms of electroweak symmetry breaking in the dileptonic vector boson scattering channel is presented. ...
Continuous-wave terahertz light from optical parametric oscillators
(2010-12-01)
Continuous-wave (cw) optical parametric oscillators (OPOs) are working horses for spectroscopy in the near and mid infrared. However, in the terahertz frequency range (0.1 to 10 THz), the pump threshold is more than 100 W ...
Design Studies for a Tracking Upgrade of the Crystal Barrel Experiment at ELSA and Installation of a Tracking Test Bench
(2010-01-04)
Ever since mankind was interested in the understanding of the universe and especially the matter in it. The fundamental building blocks of matter seem to be quarks and gluons, whose interactions are investigated in hadron ...
Schallstrahlungskontrast in MR-Phasenbildern: Methode zur Darstellung von Elastizitäts-, Schalldämpfungs- und Schallimpedanzänderungen
(2010-03-15)
Die in dieser Arbeit präsentierte Methode kombiniert Ultraschalltechniken mit der Magnetresonanztomographie (MRT). Eine Ultraschallwelle ruft in absorbierenden Medien eine statische Kraft in Schallausbreitungsrichtung ...
Investigation and Optimization of Transverse Non-Linear Beam Dynamics in the High-Energy Storage Ring HESR
(2010-03-29)
The High-Energy Storage Ring (HESR) is part of the upcoming Facility for Antiproton and Ion Research (FAIR) which is planned as a major extension to the present facility of the Helmholtzzentrum für Schwerionenforschung ...
Die Photonenmarkierungsanlage für das Crystal-Barrel/TAPS-Experiment an ELSA
(2010-01-13)
Mit dem CBELSA/TAPS-Experiment werden im Rahmen des SFB/TR 16 Messungen von Einfach- und Doppelpolarisationsobservablen in der Photoproduktion durchgeführt. Die Energie der benötigten hochenergetischen, polarisierten ...
Characterization of the Imaging Performance of the Simultaneously Counting and Integrating X-ray Detector CIX
(2010-01-07)
The CIX detector is a direct converting hybrid pixel detector designed for medical X-ray imaging applications. Its defining feature is the simultaneous operation of a photon counter as well as an integrator in every pixel ...
Pseudoelastisches Materialverhalten in der reinen Biegung
(2010-01-07)
Die vorliegende Arbeit untersucht das mechanische Verhalten von gezogenen pseudoelastischen Nickel-Titan-Legierungen in der reinen Biegung. Der Prüfaufbau garantiert zu jedem Zeitpunkt der Messung eine querkraftfreie ...
Internal and external dynamics of a strongly-coupled atom-cavity system
(2010-01-07)
A system comprised of a small number of neutral atoms coupled to the mode of a high finesse optical resonator is a model system to study light-matter interaction at the quantum level and to explore fundamental effects like ...
