Digital radial radiography on radioactive waste packages using fission neutrons
Various methods for the non-destructive characterization of radioactive waste packages are applied in routine operation for identification and quantification of their radioactive inventory. As accuracy and precision play are an important role in the final documentation, an approach based on Bayesian statistics is presented for the evaluation of transmission data measured by digital radial radiography.

Prompt gamma rays of terbium induced by inelastic scattering of fission neutrons
Prompt gamma rays of terbium emitted after (n,nʹγ) inelastic scattering reactions induced by irradiation of a terbium(III) hexahydrate (TbCl3·6H2O) sample with a beam of fission neutrons were investigated with the instrument FaNGaS (Fast Neutron-induced Gamma-ray Spectrometry) at an angle of 90° between neutron beam and detector. At sample position, the fast-neutron flux was 1.13 × 108 cm−2 s−1 and the neutron beam has an average energy of 2.30 MeV. [...]

Analysis of magnetic material properties in electrical steel using neutron grating interferometry
Universitätsbibliothek Technische Universität München 136 pp. () = Dissertation, Technische Universität München, 2023
Electric vehicles are an option to slow down climate change. In this work, we analyzed the usage of residual stress to guide the magnetic flux in electrical steel sheets (ES), which comprise the magnetic core of electric drives. [...]

Unconventional Spin Textures and Multiferroic Properties of the spiralAntiferromagnet Ba2CuGe2O7”
117p () = Masterarbeit, TUM, 2023
Ba2CuGe2O7 is a tetragonal antiferromagnetic insulator with a multitude of noncollinearmagnetic structures at low temperatures, combined with multiferroic properties.The ground state below the N´eel temperature TN = 3.05K is an antiferromagneticcycloid due to the Dzyaloshinskii-Moriya interaction. The magnetic phasediagram of Ba2CuGe2O7 has been revisited by a recent theoretical study [1], nowdescribing the emergence of a vortex-antivortex phase in a pocket of the phase diagramaround a temperature of 2.3K and a magnetic field along the crystal c-axisof 2.2 T.

IEEE () [10.1109/IRMMW-THz57677.2023.10299247]
We report on position-dependent measurements of photocarrier transport using time-resolved terahertz spectroscopy (TRTS) across a slot-die printed perovskite film of varying morphology. Using the Drude-Smith model for the photoconductivity spectra we report maximum intrinsic mobilities of 540±20 cm2V−1s−1. [...]

Layer‐By‐Layer Printed Metal Hybrid (Cs:FA)PbI$_{3}$ Perovskite Nanocrystal Solar Cells
Mixed halide perovskite nanocrystals in the form of cesium/formamidinium lead triiodide ((Cs:FA)PbI3) offer great potential for efficient and stable solar cells. To date, large-scale production with roll-to-roll compatible deposition methods remains difficult and requires detailed research on each involved processing step. [...]
