  1. 11. Multi-Strange and Charmed Antihyperon-Hyperon Physics for PANDA

    Författare :Erik Thomé; Tord Johansson; Brian Quinn; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; PANDA; FAIR; antiproton; hyperon; strangeness; charm; polarisation; spin correlation; CP violation; Nuclear Physics; Kärnfysik;

    Sammanfattning : The prospects of studying multi-strange and charmed antihyperon-hyperon physics and CP violation in hyperon decays in the upcoming PANDA experiment at FAIR, Germany, have been studied in this thesis.The angular dependence on polarisation parameters in the decay of the spin 3/2 Omega hyperon was calculated using the density matrix formalism.

  3. 12. Fusion Plasma Observations at JET with the TOFOR Neutron Spectrometer : Instrumental Challenges and Physics Results

    Författare :Maria Gatu Johnson; Matthias Weiszflog; Luciano Bertalot; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Fusion; Plasma diagnostics; Neutron Spectrometry; TOFOR; JET; ITER; time-of-flight; plasma heating; Nuclear physics; Kärnfysik; Applied Nuclear Physics; Tillämpad kärnfysik;

    Sammanfattning : The neutron spectrometer TOFOR was installed at JET in 2005 for high-rate observation of neutrons from reactions between two deuterium (D) ions. Neutron spectrometry as a fusion plasma diagnostic technique is invoked to obtain information about the velocity states of fusion fuel ions. LÄS MER

  7. 15. Neutron Spectrometry Techniques for Fusion Plasmas : Instrumentation and Performance

    Författare :Erik Andersson Sundén; Göran Ericsson; Sean Conroy; Erik Traneus; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; fusion; plasma diagnostics; neutron spectrometry; neutron spectroscopy; MPRu; magnetic proton recoil spectrometer; fusion; ITER; Nuclear physics; Kärnfysik; Fysik med inriktning mot tillämpad kärnfysik; Physics with specialization in Applied Nuclear Physics;

    Sammanfattning : Neutron are emitted from a deuterium plasma with energies around 2.5 MeV. The neutron spectrum is intimately related to the ion velocity distribution of the plasma. As a consequence, the analysis of neutron energy spectra can give information of the plasma rotation, the ion temperature, heating efficiency and fusion power. LÄS MER
