  3. 32. Flourescence properties of trendy molecules studied with synchrotron radiation

    Författare :Gemma Vall-Llosera; Elisabeth Rachlew-Källne; Ahmed Al-Khalili; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physics; Fysik;

    Sammanfattning : This thesis summarises the experimental results on molecular spectroscopy of gas phase molecules using synchrotron radiation in the UV- VUV and soft-X rays regions. The results of applying Photon Induced Fluorescence Spectroscopy (PIFS) to D2, H2S, H2O and pyrimidine are presented and discussed. LÄS MER

  4. 33. Imaging of tissue degeneration in knee osteoarthritis using magnetic resonance and synchrotron radiation

    Författare :Emma Einarsson; Malmö Medicinsk strålningsfysik; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Magnetic resonance imaging MRI ; osteoarthritis OA ; Meniscus; Chemical Exchange Saturation Transfer CEST ; Relaxation time; Synchrotron radiation X-ray tomographic microscopy;

    Sammanfattning : Osteoarthritis (OA) is a very common disease, especially in the knee. It is characterized by the breakdown of articular cartilage but involves all parts of the joint. OA is usually diagnosed at a late stage when the articular cartilage has begun to disappear. What happens before these macroscopic alterations is to alarge extent unknown. LÄS MER

  5. 34. Emittance related topics for fourth generation storage ring light sources

    Författare :Jonas Breunlin; Lunds universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; ultralow emittance; Touschek lifetime; emittance tuning; Beam diagnostics; synchrotron radiation;

    Sammanfattning : In this thesis several aspects related to a new generation of storage ring light sources are discussed. Due to a reduction of electron beam emittance, fourth generation storage rings provide synchrotron radiation sources close to the diffraction limit at X-ray wavelengths. LÄS MER

  7. 35. Momentum-space dynamics of runaway electrons in plasmas

    Författare :Adam Stahl; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; synchrotron radiation; tokamak; critical electric field; non-linear collision operator; slide-away; runaway electrons; fusion-plasma physics;

    Sammanfattning : Fast electrons in a plasma experience a friction force that decreases with increasing particle speed, and may therefore be continuously accelerated by sufficiently strong electric fields. These so-called runaway electrons may quickly reach relativistic speeds. LÄS MER
