1. 1. Plasma diagnostics for particle confinement studies in magnetic fusion devices

   Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Tillämpad kärnfysik

   Författare :Linus Hägg; [2018]
   Nyckelord :Interferometry; Interferometer; double color interferometer; two-color interferometer; Fusion; Plasma; Fusion plasma; Spectroscopy;

   Sammanfattning : This thesis investigates the performance and improves a double color interferometer setup, absolutely calibrates a line radiation Balmer H-alpha measurement setup, and uses measurements from both setups to estimate the particle confinement time of a plasma. The double colour interferometer at the magnetic confinement plasma device EXTRAP T2R measures the line integrated electron density of the plasma. LÄS MER

3. 2. Design and Calculations of a Broadband Two Color Inline Interferometer

   Kandidat-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Atomfysik

   Författare :Neven Ibrakovic; [2014]
   Nyckelord :Second Harmonic Generation; High-order Harmonic Generation; Interferometry; Achromatism; Physics and Astronomy;

   Sammanfattning : High-Order Harmonic generation (HHG) is an alternative and much more compact way of generating x-ray radiation compared to producing it in a synchrotron. In this report a two color inline interferometer is designed to superimpose electrical fields generated by a frequency doubling crystal, for the purpose of reshaping the pulse train generated in the HHG process.
