  1. 1. Neutron Spectroscopy : Instrumentation and Methods for Fusion Plasmas

    Författare :Henrik Sjöstrand; Göran Ericsson; Johan Frenje; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Neutron spectroscopy; plasma diagnostics; fusion power; fusion; plasma heating; MPRu; JET; triton burn-up; ITER; neutron yield; calibration; Fusion; 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. 4. Utilization of Low Voltage D-T Neutron Generators in Neutron Physics Studies

    Författare :Somsorn Singkarat; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; D-T neutron generator; double-differential cross-section DDX ; n-1H scattering; directional neutron detector; time-of-flight method; natural iron; scintillation fibers; neutron energy converter;

    Sammanfattning : In a small nuclear laboratory of a developing country a low voltage D-T neutron generator can be a very useful scientific apparatus. Such machines have been used successfully for more than 40 years in teaching and scientific research. LÄS MER

  7. 5. Development and Use of Neutron Scintillator Systems for Fusion Plasma Diagnostics

    Författare :Magnus Hoek; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; organic scintillators; neutron spectrometry;

    Sammanfattning : This thesis reports on research and development work, made in connection with the use of organic scintillators, for neutron spectrometry. It also gives a general review on the use of organic scintillators for the detection of neutrons generated from fusion of deuterium (D) and fusion between a mixture of deuterium and tritium (T) in thermonuclear plasmas.
