  2. 1. Modelling of Formation and Evolution of Defects and Precipitates in Fe-Cr Alloys of Reactor Relevance

    Author : Pär Olsson; Jan Källne; Jan Wallenius; Graeme Ackland; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Nuclear physics; Kärnfysik; Nuclear physics; Kärnfysik;

    Abstract : Fe-Cr alloys form the basis of many industrially important steels. Due to their excellent resistance to radiation induced swelling, ferritic steels are expected to be used for critical structural components in advanced nuclear systems, such as fast breeder reactors, accelerator driven systems and fusion reactors.

  5. 3. Development of Neutron Emission Spectroscopy Instrumentation for Deuterium and Deuterium-Tritium Fusion Plasmas at JET

    Author : Luca Giacomelli; Jan Källne; Thomas Sangster; Uppsala universitet; []
    Keywords : Nuclear physics; neutron spectroscopy; MPRu; TOFOR; JET; Radio frequency heating; Count rate; Kärnfysik;

    Abstract : The study of high power fusion plasmas at the JET tokamak has been further enhanced through the development of instrumentation for neutron emission spectroscopy (NES) measurements. This has involved the upgrade of the magnetic proton recoil (MPR) spectrometer used for deuterium-tritium plasmas earlier so that the MPRu can now be also employed for deuterium (D) plasmas.

  6. 4. Neutron Spectroscopy Studies of Heating Effects in Fusion Plasmas

    Author : Hans Henriksson; Jan Källne; Joaquín Sánchez; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Nuclear physics; neutron emission spectroscopy; diagnostic; fusion research; plasma heating; Kärnfysik; Nuclear physics; Kärnfysik; Applied Nuclear Physics; tillämpad kärnfysik;

    Abstract : High power fusion plasmas produced in the world’s largest facility for magnetic confinement experiments (JET), have been studied using the neutron emission measured with the magnetic proton recoil (MPR) spectrometer. The MPR has been used to observe plasmas since 1996 including those of deuterium-tritium leading to several fusion records and corresponding observational achievements of neutron emission spectroscopy.

  7. 5. Development and Construction of a 2.5-MeV Neutron Time-of-Flight Spectrometer Optimized for Rate (TOFOR)

    Author : Anders Hjalmarsson; Jan Källne; James Drake; Uppsala universitet; []
    Keywords : Nuclear physics; Kärnfysik;

    Abstract : A new neutron time-of-flight spectrometer optimized for high count rate (TOFOR) has been developed for the JET research tokamak. TOFOR will measure the energy distribution of neutrons emitted from the d+d → 3He+n fusion reactions in deuterium plasma. READ MORE
