  1. 1. Optical Diagnostics of Non-thermal Plasmas and Plasma-assisted Combustion

    Detta är en avhandling från Lund Report on Combustion Physics

    Författare :Jiajian Zhu; [2015]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; High-speed photography; Laser diagnostics; Planar laser-induced fluorescence; Plasma-assisted combustion; Non-thermal plasmas; Gliding arc discharge; Optical diagnostics; Particle tracking velocimetry; Fysicumarkivet A:2015:Zhu;

    Sammanfattning : Non-thermal plasma is regarded as a collection of free electrons, ions and neutral particles that are not at local thermodynamic equilibrium. The high-energetic electrons formed in non-thermal plasmas are capable of generating chemically active species and modifying chemical kinetics in practical applications. LÄS MER

  2. 2. Visible spectroscopic diagnostics application and development in fusion plasmas

    Detta är en avhandling från Stockholm : KTH

    Författare :Sheena Menmuir; KTH.; [2007]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; visible spectroscopy; fusion; Doppler shift; Doppler broadening; TECHNOLOGY Engineering physics Plasma physics with fusion; TEKNIKVETENSKAP Teknisk fysik Plasmafysik med fusion;

    Sammanfattning : Diagnostic measurements play a vital role in experiments. Without them we would be in the dark with no way of knowing what was happening; of understanding the processes and behaviour occurring; or even of judging the success or failure of our experiments. The development of fusion plasma devices is no different. LÄS MER

  3. 3. Diagnostics for advanced fusion plasma scenarios

    Detta är en avhandling från Stockholm : KTH

    Författare :Mattias Kuldkepp; KTH.; [2006]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MSE; PEM; mirror evolution; fusion; diagnostics; plasma spectroscopy; reversed field pinch; spherical tokamak; intelligent shell; PPCD; MAST; ITER; NATURAL SCIENCES Physics Atomic and molecular physics Molecular physics; NATURVETENSKAP Fysik Atom- och molekylfysik Molekylfysik;

    Sammanfattning : Over the past decade, fusion research has showed the potential of being a main candidate for energy production for future generations. Further advances in improved fusion performance are therefore vital. This thesis focuses on advanced fusion plasma scenarios and their diagnostic requirements. LÄS MER

  4. 4. Neutron Spectroscopy Instrumentation and Methods for Fusion Plasmas

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Henrik Sjöstrand; Uppsala universitet.; [2008]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Neutron spectroscopy; plasma diagnostics; fusion power; fusion; plasma heating; MPRu; JET; triton burn-up; ITER; neutron yield; calibration; NATURAL SCIENCES Physics Geocosmophysics and plasma physics Fusion; NATURVETENSKAP Fysik Geokosmofysik och plasmafysik Fusion;

    Sammanfattning : When the heavy hydrogen isotopes deuterium (D) and tritium (T) undergo nuclear fusion large amounts of energy are released. At the Joint European Torus (JET) research is performed on how to harvest this energy. Two of the most important fusion reactions, d+d→3He+n (En = 2.5 MeV) and d+t→4He+n (En = 14 MeV), produce neutrons. LÄS MER

  5. 5. Making TOFu Fusion Plasma Neutron Emission Spectrometry with a Fully Digital Data Acquisition System

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Mateusz Skiba; Uppsala universitet.; [2016]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; fusion; plasma diagnostics; neutron spectrometry; TOFOR; tokamak; JET; digital data acquisition; Fysik med inriktning mot tillämpad kärnfysik; Physics with specialization in Applied Nuclear Physics;

    Sammanfattning : TOFu (Time-Of-Flight upgrade) is a fully digital data acquisition system based on 1 GSPS, 12 bit digitisers for the TOFOR (Time-Of-Flight spectrometer Optimised for Rate) fusion neutron spectrometer at JET. The system has been assessed, developed and subsequently tested during experimental campaigns at JET. LÄS MER
