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

   Author : Henrik Sjöstrand; Göran Ericsson; Johan Frenje; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Neutron spectroscopy; plasma diagnostics; fusion power; fusion; plasma heating; MPRu; JET; triton burn-up; ITER; neutron yield; calibration; Fusion; Fusion;

   Abstract : 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. READ MORE

4. 2. A Fast Pixelated Thermal-Neutron Detector

   Author : Emil Rofors; Kärnfysik; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; SoNDe; thermal-neutron detector; GS20 scintillator; Li-glass; H12700A MAPMT; position-dependent response; alpha-particle; proton; deuteron; neutron; ESS; SKADI;

   Abstract : This thesis presents the study of a position-sensitive scintillation-based detector called the Solid-State Neutron Detector (SoNDe). SoNDe is being developed for cold- and thermal-neutron detection at the small-angle neutron scattering (SANS) instrument SKADI at the European Spallation Source (ESS), currently under construction in Lund, Sweden.

5. 3. Neutron-Deuteron Scattering and Three-Body Interactions

   Author : Philippe Mermod; Jan Blomgren; Steven Vigdor; Uppsala universitet; []
   Keywords : Nuclear physics; three-body force; neutron; deuteron; elastic scattering; angular distribution; Faddeev equations; Kärnfysik;

   Abstract : High-precision differential cross section data of the neutron-deuteron elastic scattering reaction at 95 MeV are presented. The neutron-proton scattering differential cross section was also measured and used as a reference to allow an accurate absolute normalization of the neutron-deuteron data. READ MORE

7. 5. Neutron Irradiation Techniques

   Author : Julius Scherzinger; Kärnfysik; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; actinide Be; fast-neutrons; NE-213 liquid scintillator; He-4 scintillators; pulse-shape discrimination; Cf-252; absolute detection efficiency; neutron irradiation; Fysicumarkivet A:2016:Scherzinger;

   Abstract : The He-3 “crisis” has become a fact in the last decade and large scale neutron detectors based on He-3 technologies have become unaffordable. This new He-3 reality has resulted in a major effort worldwide to develop replacement neutron-detector technologies. READ MORE
