1. 16. Thin Films and Deposition Processes Studied by Soft X-Ray Spectroscopy

   Författare :Björn Gålnander; Uppsala universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; Materialvetenskap; Materials science; Teknisk materialvetenskap; Solid State Physics; fasta tillståndets fysik;

   Sammanfattning : This thesis deals with studies of thin films using soft x-ray emission spectroscopy. Thin films are frequently used in optical, semiconductor and magnetic applications, and along with the development of thin film deposition techniques, there is a growing need for thin film characterisation and production control.

3. 17. Electron-Impact Liquid-Jet Water-Window X-ray Sources

   Författare :Peter Anders Skoglund Lindberg; Hans M. Hertz; Oscar Tjernberg; KTH; []
   Nyckelord :TECHNOLOGY; TEKNIKVETENSKAP;

   Sammanfattning : This Thesis describes the development and characterization of a soft x-ray liquidjet-anode electron-impact source. With a water-jet target the primary emission is the O Kα line at 525 eV. This is close to the lower edge of the water-window, a spectral region lacking simple laboratory sources. LÄS MER

4. 18. Double Excitations in Helium Atoms and Lithium Compounds

   Författare :Marcus Agåker; Jan-Erik Rubensson; Leif Karlsson; David Ederer; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Atomic and molecular physics; Soft X-ray emission; resonant inelastic X-ray scattering; double excitations; lithium halide; helium; Atom- och molekylfysik;

   Sammanfattning : This thesis addresses the investigation of doubly excited 2l´nl states in helium atoms and double core excitations in solid lithium compounds.Measurements on He are made in field free environments and under the influence of electric and magnetic fields, using synchrotron based inelastic photon scattering.

7. 20. Resonant Soft X-ray Spectroscopic Studies of Light Actinides and Copper Systems

   Författare :Anders Modin; Sergei Butorin; Lars Werme; Joseph Nordgren; Kevin Smith; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Atomic and molecular physics; Atom- och molekylfysik; Fysik; Physics;

   Sammanfattning : Light actinides and copper systems were studied using resonant soft X-ray spectroscopy.An instrumental and experimental setup for soft X-ray spectroscopy meeting the requirements of a closed source for radioactivity was developed and described in detail. The setup was used for studies of single-crystal PuO2 oxidation. LÄS MER
