  1. 11. A Theoretical Investigation of the Nitrogen-Vacancy Center in Diamond as a Single Molecule Sensor and Qubit : Charging through Explicit Electron Donors

    Författare :Robin Löfgren; Andreas Larsson; Sven Öberg; Corina Etz; Fedor Jelezko; Luleå tekniska universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Applied Physics; Tillämpad fysik;

    Sammanfattning : The NV-center in diamond is one of the most well researched defects to date. Since its discovery in the 1960’s, a large body of experimental as well as theoretical work have been produced, investigating its properties and applications. LÄS MER

  3. 12. Studies of cosmic rays with the anticoincidence system of the PAMELA satellite experiment

    Författare :Silvio Orsi; Mark Pearce; Martin Pohl; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; astrophysics; astroparticle physics; antimatter; organic scintillators; cosmic rays; trapped particles; Astroparticle physics; Astropartikelfysik;

    Sammanfattning : PAMELA is a satellite-borne experiment designed to study the charged component of the cosmic radiation of galactic, solar and trapped nature. The main scientific objective is the study of the antimatter component of cosmic rays over a wide range of energies (antiprotons: 80 MeV–190 GeV, positrons: 50 MeV–270 GeV). LÄS MER

  4. 13. The Anticoincidence System of the PAMELA Satellite Experiment : Design of the data acquisition system and performance studies

    Författare :Johan Lundquist; Mark Pearce; Tony Weidberg; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; PAMELA; satellites; astroparticle physics; electronics; anticoincidence system; trigger system; Astroparticle physics; Astropartikelfysik;

    Sammanfattning : PAMELA is a satellite-borne cosmic ray experiment. Its primary scientific objective is to study the antiproton and positron components of the cosmic radiation. This will be done with unprecedented statistics over a wide energy range (~10MeV to ~100GeV). LÄS MER

  5. 14. Activity concentrations of radionuclides in energy production from peat, wood chips and straw

    Författare :Robert Hedvall; Kärnfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Radionuclides; peat; wood; chips; straw; bioenergy; biomass; district heating; emission; Cs; Physics; Chernobyl; Radioactivity; Fysik; Technological sciences; Teknik; Fysicumarkivet A:1997:Hedvall;

    Sammanfattning : In this thesis quantitative analyses of radionuclide concentrations in bioenergy fuels such as peat, wood chips and straw are presented. For comparison a brief description is included of radionuclide concentrations and radiation doses from other sources of power and also from some industrial applications. LÄS MER

  7. 15. Phenomenology of Charged Higgs Bosons and B-meson Decays

    Författare :David Eriksson; Johan Rathsman; Gunnar Ingelman; Fabio Maltoni; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Supersymmetry; Beyond Standard Model; B-Physics; Charged Higgs Boson; LHC; QCD; Spin Correlations; CMSSM; NUHM; Elementary particle physics; Elementarpartikelfysik;

    Sammanfattning : For more than 30 years the Standard Model has been the theoretical foundation for particle physics. The theory has been verified successfully by experimental tests. Its biggest shortcoming is the non-discovery of the Higgs boson,responsible for giving the other particles masses. LÄS MER
