Light-induced current in Weyl semi-metals
Weyl semi-metals: materials with peculiar electronic properties For many areas of industry and everyday life the effective transformation of light for the generation of electric current is of high importance – among others for the harvesting of clean energy, image-acquisition techniques in different areas, communication technology, as well as biological and chemical detectors. During my […]

High Voltage tests for mirror electrodes of a 30 keV Multi-Reflection Time-of-Flight device
Abstract The MIRACLS experiment at the ISOLDE facility at CERN seeks to overcome the sensitivity limit of conventional Collinear Laser Spectroscopy of short-lived radionuclides by extending the laser-ion interaction time by trapping ions of exotic isotopes in a Multi-Reflection Time-of-Flight device (MR-ToF). In the MR-ToF device the ions are confined between two electrostatic mirrors, which […]Abstract The MIRACLS experiment at the ISOLDE facility at CERN seeks to overcome the sensitivity limit of conventional Collinear Laser Spectroscopy of short-lived radionuclides by extending the laser-ion interaction time by trapping ions of exotic isotopes in a Multi-Reflection Time-of-Flight device (MR-ToF).

Simulation of X-ray spectra of astrophysical sources in the laboratory
Simulation of X-ray spectra of astrophysical sources in the laboratory Laboratory measurements in support of X-ray astrophysics Energetic processes in astrophysical objects cause emission of a continuum of X-radiation. Material in the environment of these objects imprints additional spectral line features onto these spectra. Their line energies and intensities are used to determine elemental abundances, […]Simulation of X-ray spectra of astrophysical sources in the laboratory Laboratory measurements in support of X-ray astrophysics Energetic processes in astrophysical objects cause emission of a continuum of X-radiation.

Vierpunktmessungen am Supraleiter FeTeSe
Mein Name ist Josef Freudenstein und ich bin seit 2016 Mitglied im Forschungsstudiengang Physik der Universität Regensburg. Ein Highlight meines Studiums war ein Forschungsprojekt, das ich im Sommer 2018 am Boston College in den USA durchführen durfte. Ziel dieses Praktikums war die Erforschung eines Supraleiters. Vereinfacht gesagt handelt es sich dabei um Materialien, die unterhalb […]
