Characterization of Ultrashort Electron Bunches at the SINBAD-ARES Linac
[DESY-THESIS-2019-026]
Hamburg : Verlag Deutsches Elektronen-Synchrotron, DESY-THESIS 176 pp. () [10.3204/PUBDB-2019-04190] = Dissertation, Universität Hamburg, 2019  GO
The generation of ultrashort electron bunches is an active area of research in accelerator physics. A key application of such bunches is the injection into novel accelerators with high-frequency accelerating fields, such as laser-wakefield plasma accelerators or dielectric laser accelerators. [...]

Modelling the coincident observation of a high-energy neutrino and a bright blazar flare
[arXiv:1807.04275]
In September 2017, the IceCube Neutrino Observatory recorded a very-high-energy neutrino in directional coincidence with a blazar in an unusually bright gamma-ray state, TXS0506 + 056 (refs1,2). Blazars are prominent photon sources in the Universe because they harbour a relativistic jet whose radiation is strongly collimated and amplified. [...]

Effect of Solvent Additives on the Morphology and Device Performance of Printed Nonfullerene Acceptor Based Organic Solar Cells
Printing of active layers of high-efficiency organic solar cells and morphology control by processing with varying solvent additive concentrations are important to realize realworld use of bulk-heterojunction photovoltaics as it enables both up-scaling and optimization of the device performance. In this work, active layers of the conjugated polymer with benzodithiophene units PBDB-T-SF and the nonfullerene small molecule acceptor IT-4F are printed using meniscus guided slot-die coating.

Relationship between structure and molecular interactions in monolayers of specially designed aminolipids
Nanoscale advances 1(9), 3529 - 3536 () [10.1039/C9NA00355J]  GO
Artificial cationic lipids are already recognized as highly efficient gene therapy tools. Here, we focus on another potential use of aminolipids, in their electrically-uncharged state, for the formation of covalently cross-linked, one-molecule-thin films at interfaces. [...]

Low-temperature luminescence spectrum of forbidden $4f^{13} 5d‐4f^{14}$ transitions in $CaF_2:Lu^{3+}$ crystal
$Lu^{3+}$ + $4f^{13} 5d‐4f^{14}$ luminescence in $CaF_2:Lu^{3+}$ crystal at 8 K was studied with a high spectral resolution using synchrotron radiation excitation. Absence of a zero-phonon line in the recorded spectrum was explained and features in the recorded spectrum were reproduced by simulation based on the microscopic model of electron-phonon interaction and the developed theory of non-Condon spectra..

Characterizing transmissive diamond gratings as beam splitters for the hard X-ray single-shot spectrometer of the European XFEL
The European X-ray Free Electron Laser (EuXFEL) offers intense, coherent femtosecond pulses, resulting in characteristic peak brilliance values a billion times higher than that of conventional synchrotron facilities. Such pulses result in extreme peak radiation levels of the order of terawatts cm−2 for any optical component in the beam and can exceed the ablation threshold of many materials. [...]

Sensitization of luminescence from $Sm^{3+}$ ions in fluoride hosts $K_2YF_5$ and $K_2GdF_5$ by doping with $Tb^{3+}$ ions
Spectroscopic properties and energy transfer mechanisms for isostructural fluoride $K_2YF_5$ and $K_2GdF_5$ crystals singly and doubly doped with different concentrations of $Tb^{3+}$ and $Sm^{3+}$ ions have been investigated under excitation in the deep ultraviolet (DUV) and vacuum UV (VUV) spectral regions. In these hosts luminescence of $Sm^{3+}$ ions is enhanced under DUV excitation by doping with $Tb^{3+}$ ions, namely, the $Sm^{3+}$ excitation spectra show additional intense excitation in the region of $Tb^{3+}$ spin-allowed 4f – 5d transitions at 200–220 nm due to energy transfer from $Tb^{3+}$ to Sm3+.

Interfacial premelting of ice in nano composite materials
The interfacial premelting in ice/clay nano composites was studied by high energy X-ray diffraction. Below the melting point of bulk water, the formation of liquid water was observed for the ice/vermiculite and ice/kaolin systems. [...]

Cation ordering, ferrimagnetism and ferroelectric relaxor behavior in $Pb(Fe_{1−x}Sc_{x})_{2∕3}W_{1∕3}O_{3}$ solid solutions
Ceramic samples of the multiferroic perovskite Pb(Fe1−xScx)2∕3W1∕3O3 with 0 ≤ x ≤ 0.4 have been synthesized using a conventional solid-state reaction method, and investigated experimentally and theoretically using first-principle calculations. Rietveld analyses of joint synchrotron X-ray and neutron diffraction patterns show the formation of a pure crystalline phase with cubic (Fm3̅m) structure with partial ordering in the B-sites [...]
