  1. 1. Nonlinear Optics Studies on the MAX IV Storage Rings

    Författare :David K Olsson; Lunds universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; accelerator physics; synchrotron; storage ring; magnetic optics; non-linear optics; characterisation; optimisation;

    Sammanfattning : The MAX IV Laboratory in Lund, Sweden, houses two electron storage rings operating at the energies 1.5, and 3 GeV. Both of these produce high-brilliance synchrotron radiation for beamline users. While the 1. LÄS MER

  3. 2. Accelerator physics studies of the MAX-lab storage rings

    Författare :Magnus Sjöström; Lunds universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Electron accelerator; linear optics; storage ring; characterisation; synchrotron radiation; emittance; intrabeam scattering; electron beam profile;

    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. 3. On the Challenges for Time-of-Flight Electron Spectroscopy at Storage Rings

    Författare :Christian Stråhlman; Lunds universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; time-of-flight; photoelectron spectroscopy; MAX IV; storage ring; detector gating; chopper; coincidence spectroscopy;

    Sammanfattning : Time-of-flight (TOF) techniques for energy analysis have been common in electron spectroscopy for many decades. TOF-based electron spectrometers benefit from higher transmission and information rate compared to their main competitor: the hemispherical analyser; the drawback being their lower energy resolution.

  5. 4. An Investigation of Mixed Cellulose Esters and Acyclic Polyacetates: Effects of Side-Chain Lengths and Degrees of Ring-Opening

    Författare :Robin Nilsson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; water interactions; oxygen permeation; storage modulus; ring-opening; water sorption; cellulose esters; side-chains; acyclic cellulose acetate;

    Sammanfattning : Bio-based polymers produced from natural sources are gaining an increased interest as potential replacement for today’s conventional fossil-based plastic polymers. Their use is already wide in many large-scale industrial areas such as healthcare, personal care, and food. LÄS MER

  7. 5. Spectroscopic study of titanium monohydride and storage ring experiments

    Författare :Mathias Danielsson; Ulf Sassenberg; Mats Larsson; Peder Royen; Olli Launila; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TiH; TiD; transition metal hydride; dissociative recombination; Chemical physics; Kemisk fysik; kemisk fysik; Chemical Physics;

    Sammanfattning : This thesis describes two projects, spectroscopy of the astrophysically relevant molecule TiH and its isotopologue TiD, and the dissociative recombination (DR) reaction of astrophysically and atmospherically relevant molecules. Emphasis in the thesis is on the first project. LÄS MER
