  2. 21. Design and Implementation of RF Kickers in MAX IV

    Author : David Olsson; Lunds universitet; []
    Keywords : Accelerator cavities; Beam choppers; Bunch-by-bunch feedback; RF kickers; Striplines;

    Abstract : The MAX IV facility in Lund, Sweden, consists of two storage rings for production of synchrotron radiation, and a full-energy LINAC for top-up injections. The LINAC also delivers short high-intensity electron bunches to a short pulse facility. READ MORE

  4. 22. Precision measurements on negative ions

    Author : Moa Kristiansson; Henning T. Schmidt; Dag Hanstorp; Henning Zettergren; Christophe Blondel; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Negative ions; Atomic physics; Precision measurement; Electron affinity; Photodetachment; Physics; fysik;

    Abstract : In this thesis, experiments with negative ions performed at the DESIREE facility are presented. DESIREE consists of two electrostatic storage rings operated at 13 K. The low temperature in combination with a low pressure allows for storage times of the negative ion beams to be up to several hours. READ MORE

  5. 23. Studies of X-Ray Optics And Polarimetry For Synchrotron Radiation

    Author : Walan Grizolli; Lunds universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; X-ray optics; polarimetry; synchrotron radiation instrumentation.;

    Abstract : Synchrotron radiation sources have greatly contributed to the progress in many fields of science. The development of the storage ring technologies have made possible to obtain very low emittance electron beams, which together with the use of undulators allow to guide a very high photon flux into a very small beam size required by the experiments.

  6. 24. The Curious Case of Hot Metal Clusters : Spontaneous decay of excited, small silver and copper cluster anions in DESIREE

    Author : Emma Anderson; Henning Schmidt; Daniel Harding; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physics; fysik;

    Abstract : Clusters anions are complex systems which, when formed with high internal energies, can decay via fragmentation and/or electron loss and may also cool via photon emission (radiative cooling). By studying the spontaneous decay mechanisms of small metal clusters, we can gain insight into the structure and properties of these systems. READ MORE

  7. 25. Time-Resolved Spectroscopy and Intensity Measurements of Singly Charged Ions

    Author : Erik Bäckström; Sven Mannervik; Andreas Wolf; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; fysik; Physics;

    Abstract : This thesis is mainly concerned with investigations of spontaneous radiatively decaying states in both negative and positive singly charged ions. When possible, the measured lifetime of the state has been combined with branching fractions in order to derive the absolute transition probability (A-value) between different quantum states.
