Development of a serial powering scheme and a versatile characterization system for the ATLAS pixel detector upgrade
(2017-08-22)
In order to increase the probability of new discoveries the LHC will be upgraded to the HL-LHC. The upgrade of the ATLAS detector is an essential part of this program. The entire ATLAS tracking system will be replaced by ...
Active Plasmonic and Dielectric Nanoantennas
(2017-08-10)
This thesis presents results on the fabrication, investigation and characterization of active optical nanoantennas. The three partial results in order of their occurrence are: (i) The demonstration of the operational ...
Testing the Quantumness of Atom Trajectories
(2017-05-15)
This thesis reports on a novel concept of state-dependent transport, which achieves an unprecedented control over the position of individual atoms in optical lattices. Utilizing this control I demonstrate an experimental ......
Performance evaluation of a fully depleted monolithic pixel detector chip in 150 nm CMOS technology
(2017-09-01)
The depleted monolithic active pixel sensor (DMAPS) is a new concept integrating full CMOS circuitry onto a (fully) depletable silicon substrate wafer. The realization of prototypes of the DMAPS concept relies on the ...
Magnetic Outflows in the Virgo Galaxy NGC 4388
(2017-07-21)
We investigate the effects of ram pressure on the ordered magnetic field of the edge-on Virgo galaxy NGC 4388 hosting a radio halo and strong nuclear outflows. New radio images in total and polarized intensity were obtained ...
Materialmodifikationen in Lithiumniobat- und Lithiumtantalat-Kristallen durch Ionenbestrahlung
(2017-05-22)
Die künstlich hergestellten Kristalle Lithiumniobat (LiNbO3) und das eng verwandte Lithiumtantalat (LiTaO3) sind bewährte Ausgangsmaterialien zur Herstellung aktiver und passiver Bauelemente, die Licht ...
Weak Lensing–X-ray Scaling Relations for a High Redshift Galaxy Clusters Sample
(2017-07-21)
Accurate cosmology through large X-ray selected galaxy cluster samples will rely on accurate mass estimates and well-calibrated mass-observable relations. The comparison of independent approaches, such as X-ray and ...
A method for evaluating the role of gold nanoparticles in monochromatic x-ray studies
(2017-07-24)
To promote the use of gold nanoparticles as an enhancement agent from a principle concept into therapeutic applications, it is imperative to obtain detailed knowledge of the nanoparticle-induced radiobiological mechanisms. ...
A gateway to new physics: direct measurement of the top Yukawa coupling to the Higgs boson
(2017-08-23)
The top quark has the largest Yukawa coupling in the Standard Model, is the main contribution to the Higgs mass $m_H$ corrections and defines the evolution of the Higgs effective potential with the energy, together with ...
Magnetic Resonance Rheology on Phantoms and Human Brains
(2017-07-05)
In this thesis first systematic measurements on phantoms and human brains using Magnetic Resonance Rheology (MRR) are presented and means to evaluate the acquired data are investigated.
