  1. 1. Neutron induced light-ion production from iron and bismuth at 175 MeV

    Author : Riccardo Bevilacqua; Stephan Pomp; Magnus Wolke; Uppsala universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; neutron induced reactions; light-ion production; quasi-monoenergetic neutron beam; nuclear data; accelerator driven systems; Nuclear physics; Kärnfysik; Nuclear Physics; kärnfysik; Applied Nuclear Physics; tillämpad kärnfysik;

    Abstract : Light-ions (protons, deuterons, tritons, 3He and α articles) production in the interaction of 175 MeV neutrons with iron and bismuth has been measured using the Medley setup at the The Svedberg Laboratory (TSL) in Uppsala. These measurements have been conducted in the frame of an international collaboration whose aim is to provide the scientific community with new nuclear data of interest for the development of Accelerator Driven Systems, in the range of 20 to 200 MeV.

  2. 2. Fusion Plasma Observations at JET with the TOFOR Neutron Spectrometer : Instrumental Challenges and Physics Results

    Author : Maria Gatu Johnson; Matthias Weiszflog; Luciano Bertalot; Uppsala universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Fusion; Plasma diagnostics; Neutron Spectrometry; TOFOR; JET; ITER; time-of-flight; plasma heating; Nuclear physics; Kärnfysik; Applied Nuclear Physics; Tillämpad kärnfysik;

    Abstract : The neutron spectrometer TOFOR was installed at JET in 2005 for high-rate observation of neutrons from reactions between two deuterium (D) ions. Neutron spectrometry as a fusion plasma diagnostic technique is invoked to obtain information about the velocity states of fusion fuel ions. READ MORE

  5. 5. Neutron Spectrometry Techniques for Fusion Plasmas : Instrumentation and Performance

    Author : Erik Andersson Sundén; Göran Ericsson; Sean Conroy; Erik Traneus; Uppsala universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; fusion; plasma diagnostics; neutron spectrometry; neutron spectroscopy; MPRu; magnetic proton recoil spectrometer; fusion; ITER; Nuclear physics; Kärnfysik; Fysik med inriktning mot tillämpad kärnfysik; Physics with specialization in Applied Nuclear Physics;

    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
