The implementation of a Depleted Field Effect Transistor (DEPFET) in each pixel of the DSSC (DEPFET Sensor with Signal Compression) X-ray camera for the European XFEL is intended to provide the appropriate signal compression at high injection levels and low noise figure. The aim of this work is the assessment of the non-linear DEPFET response. [...]

We report on pulse contrast characterization of the output of a gas-filled multi-pass cell employed for 20-fold compression of a high-power Yb:YAG laser. We demonstrate an energy content of 80% in the compressed fs pulse..

The technique of dielectric laser acceleration (DLA) utilizes the strong field gradients generated by intense laser light near the surfaces of microscopic photonic structures, possibly allowing compact accelerator devices. We report on the infrared laser system at the SINBAD facility at DESY, where first DLA experiments with relativistic electrons pre-accelerated by the ARES linear accelerator started in late 2020.

Multiple in situ X-ray diffraction experiments of temperature controlled laser line hardening processes have been carried out at the German Electron Synchrotron (DESY) in Hamburg, Germany. During the process, the local strain and stress evolution were monitored using synchrotron radiation with a time resolution of 50 Hz with a spatial resolution of less than Ø1 mm. [...]

Insects show a plethora of different mandible shapes. It was advocated that these mandible shapes are mainly a function of different feeding habits. [...]

The FLASH 1 beamline at DESY will be upgraded from fixed to variable gap undulators in the next years. For this the vacuum beamline has to be adapted. [...]

Chapter Content: Introduction, Polymer Film Deposition Techniques, Homopolymer and Polymer Blend Films, Amorphous films, Semi-crystalline films, Blend films, Block Copolymer Films, Amorphous block copolymer films, Semi-crystalline block copolymer films, Orientational order in block copolymer films, Random Copolymer Films with a Crystallizable Mer Unit, Concluding Remarks, Acknowledgments, References.Introduction:Organic films on planar surfaces have gained considerable interest for more than two decades.1 Since then, they have been developed for applications such as protective coatings in corrosive environments with added self-healing properties, as gas-sensors, and as permeation-barriers in the packaging and food industry. A significantly reduced gas permeation in polymer composite films filled with clay indicate the crucial role of microstructural properties for the functional performance of organic polymer films.Easy-to-functionalize surfaces based on polymer coatings with tunable surface chemistries permit today the implementation of desired biological reactions like the resistance to protein adsorption or bacterial adherence and support the healing process after the insertion of a medical implant.A nanometre scale surface topography can significantly influence the protein adsorption and, as such, the interactions of cells and bacteria.

Neodymium, a Rare Earth with low solid solubility in Mg is an ideal alloying element to improve the yield strength and creep resistance cost effectively. The addition of Zn achieves a further improvement; however, its influence on the intermetallic phases in the Mg–Nd–Zn ternary system is not yet fully understood. [...]

While we expect quantum computers to surpass their classical counterparts in the future, current devices are prone to high error rates and techniques to minimise the impact of these errors are indispensable. There already exists a variety of error mitigation methods addressing this quantum noise that differ in effectiveness, and scalability. [...]
