1. Electron - Ion Recombination Studies of Astrophysically Relevant Ions : Storage Ring and Electron Beam Ion Trap Based Measurements
Sammanfattning : This thesis contains experimental work that was performed at two state-of-the art devices for electron-ion collision physics, at a heavy-ion storage ring and at an Electron Beam Ion Trap. As a result, absolute recombination rate coefficients for H-like Si, He-like Si, Be-like Si, and Na-like Si, as well as Be-like Ne, Na-like S and Na-like Ar are reported over a wide energy range from μeV to keV.

2. Electron - Ion Recombination Data for Plasma Applications : Results from Electron Beam Ion Trap and Ion Storage Ring
Sammanfattning : This thesis contains results of electron-ion recombination processes in atomic ions relevant for plasma applications. The measurements were performed at the Stockholm Refrigerated Electron Beam Ion Trap (R-EBIT) and at the CRYRING heavy-ion storage ring. LÄS MER
3. Accelerator physics studies of the MAX-lab storage rings
Sammanfattning : Within research, synchrotron radiation is a highly useful probe for the study of materials, their properties and structures. Currently, no other radiation source allows the combination of high intensity and short wavelengths. LÄS MER
4. Electron beam sizes and lifetimes at MAX II and MAX III
Sammanfattning : The MAX II and MAX III synchrotron light sources at MAX-lab provide synchrotron radiation for experiments in a wide variety of research fields. The synchrotron radiation is emitted by ultra-relativistic electrons circulating in electron storage rings. LÄS MER
5. Electron beam profile measurements and emittance manipulation at the MAX-laboratory
Sammanfattning : The emittances of the electron beams at the MAX-laboratory accelerator system have been studied. Apart from the build-up of the diagnostic tools for precise determination of the beam spatial profiles, the objectives have been: a) to verify the accelerator design emittances at low currents and to try to determine the emittances also at high currents; b) to investigate possibilities to manipulate the emittances.
