1. Neutron Spectroscopy : Instrumentation and Methods for Fusion Plasmas
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

3. Neutron Spectrometry Techniques for Fusion Plasmas : Instrumentation and Performance
Abstract : Neutron are emitted from a deuterium plasma with energies around 2.5 MeV. The neutron spectrum is intimately related to the ion velocity distribution of the plasma. As a consequence, the analysis of neutron energy spectra can give information of the plasma rotation, the ion temperature, heating efficiency and fusion power. READ MORE

4. Characterisation of the Neutron Wall and of Neutron Interactions in Germanium-Detector Systems
Abstract : A Monte Carlo simulation of the Neutron Wall detector system has been performed using Geant4, in order to define optimum conditions for the detection and identification of multiple neutrons. Emphasis was put on studying the scattering of neutrons between different detectors, which is the main source of the apparent increase of the number of detected neutrons. READ MORE

5. Experimental Studies of Neutron Emission Induced by Heavy-Ion Scattering
Abstract : A beam of 250A MeV 17O ions was scattered from argon and xenon targets. The large excess of fast neutrons compared with statistical model calculations that was observed earlier for xenon, was confirmed and found for argon as well. READ MORE
