6. Experimental Techniques for Studies in Atomic & Molecular Physics
Sammanfattning : This thesis is based on a selection of six different experimental techniques used for studies in atomic and molecular physics. The techniques analysed in the thesis are compared to find similarities in strategies and ways to avoid sources of error.Paper 1 deals with collision based spectroscopy with 60 keV Xe6+ ions on sodium and argon gas targets.

7. Elastic Stability and Piezoelectric Power Generation Using ZnO Nanostructures
Sammanfattning : Nanotechnology combines the effort between science and engineering using the approaches of either top-to-bottom or bottom-to-top techniques. A hybrid approach of the above techniques is also used for the fabrication of nanodevices. LÄS MER
8. Probing Electron Correlation on the Attosecond Timescale
Sammanfattning : This thesis describes how photoemission stimulated by an attosecond pulse train (APT) can be used to extract information on electron correlation in simple quantum systems such as atoms. The emission of the electron by an APT induces a reorganization of the electrons remaining in the ion core. LÄS MER
9. Simulation of runaway electron generation during plasma shutdown by impurity injection
Sammanfattning : Disruptions are dangerous instabilities in tokamaks that should be avoided or mitigated. One possible disruption mitigation method is to inject impurities into the plasma to shut it down in a controlled way. Runaway Electrons (REs) can be generated after the plasma is cooled down bythe impurities and these electrons can damage the tokamak. LÄS MER
10. High Resolution Dielectronic Recombination Studies at CRYRING
Sammanfattning : The works presented in this thesis are based on experimental studies on dielectronic recombination (DR) at the Stockholm storage ring CRYRING. The experiments have taken full advantage of the low energy spread of the electron beam provided by the electron cooler of the ring. Energy resolution of 10-1eV at full width half maximum has been achieved. LÄS MER
