1. Neutron Spectroscopy : Instrumentation and Methods for Fusion Plasmas
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
2. Neutron-Deuteron Scattering and Three-Body Interactions
Sammanfattning : 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. LÄS MER
3. Neutron Irradiation Techniques
Sammanfattning : 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. LÄS MER

5. A Fast Pixelated Thermal-Neutron Detector
Sammanfattning : 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.
