1. Constructing and Commissioning HELIOS – A High Harmonic Generation Source for Pump-Probe Measurements with sub 50 fs Temporal Resolution The Development of Experimental Equipment for Extreme Ultraviolet Spectroscopy
University dissertation from Uppsala : Acta Universitatis UpsaliensisAbstract : This thesis presents HELIOS, an in-house laboratory for time-resolved pump-probe spectroscopy with extreme-ultraviolet (XUV) probe radiation. A wide span of pump wavelengths can be generated using commercial laser equipment while XUV probe radiation is generated via a high harmonic generation process in a noble gas delivering probe photons with energies between 20 eV and 72 eV.

2. Experimental studies of cluster ions containing water, ammonia, pyridine and bisulphate
University dissertation from Uppsala : Acta Universitatis UpsaliensisAbstract : Molecular cluster ions are fascinating subjects of study. Bridging the size gap between molecules and bulk, they often display non-trivial size dependent behaviour and properties. READ MORE

3. Multi-Electron and Multi-Ion Coincidence Spectroscopy of Single-Photon Ionization Processes in Molecules
University dissertation from Göteborgs universitetAbstract : This thesis presents experimental investigations of multi-electron and multi-electron-multi-ion coincidence measurements of samples in the gas phase utilizing a versatile time-of-flight magnetic bottle spectrometer technique. These investigations of multiply ionized atomic and molecular species provide valuable information on, and understanding of, ionization processes and dissociation mechanisms highly relevant to the development of electronic structure theories.

5. Characterisation of the Neutron Wall and of Neutron Interactions in Germanium-Detector Systems
University dissertation from Uppsala : Acta Universitatis UpsaliensisAbstract : A Monte Carlo simulation of the Neutron Wall detector system has been performed using Geant4, in order to define optimum conditions for the detection and identification of multiple neutrons. Emphasis was put on studying the scattering of neutrons between different detectors, which is the main source of the apparent increase of the number of detected neutrons. READ MORE
