2. 16. Study of Collimated Neutron Flux Monitors for MAST and MAST Upgrade

   Author : Siriyaporn Sangaroon; Göran Ericsson; Marco Cecconello; Matthias Weiszflog; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Fusion; Plasma diagnostics; Neutron camera; collimated neutron flux monitor; MAST; MAST Upgrade; ITER; Applied Nuclear Physics; Tillämpad kärnfysik;

   Abstract : Measurements of the neutron emission, resulting from nuclear fusion reactions between the hydrogen isotopes deuterium and tritium, can provide a wealth of information on the confinement properties of fusion plasmas and how these are affected by Magneto-Hydro-Dynamic (MHD) instabilities.This thesis describes work aimed to develop neutron measurement techniques for nuclear fusion plasma experiments, specifically regarding the performance and design of collimated neutron flux monitors (neutron cameras) for the Mega Ampere Spherical Tokamak, MAST, and for MAST Upgrade.

4. 17. 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

5. 18. Making TOFu : Fusion Plasma Neutron Emission Spectrometry with a Fully Digital Data Acquisition System

   Author : Mateusz Skiba; Göran Ericsson; Anders Hjalmarsson; Carl Hellesen; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; fusion; plasma diagnostics; neutron spectrometry; TOFOR; tokamak; JET; digital data acquisition; Fysik med inriktning mot tillämpad kärnfysik; Physics with specialization in Applied Nuclear Physics;

   Abstract : TOFu (Time-Of-Flight upgrade) is a fully digital data acquisition system based on 1 GSPS, 12 bit digitisers for the TOFOR (Time-Of-Flight spectrometer Optimised for Rate) fusion neutron spectrometer at JET. The system has been assessed, developed and subsequently tested during experimental campaigns at JET. READ MORE

6. 19. Exploring local governance in urban planning and development : the case of Lindholmen, Göteborg

   Author : Åsa von Sydow; Göran Cars; Thord Strömberg; KTH; []
   Keywords : Social sciences; governance; urban regiome theory; urban planning and development; governing process; agenda; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP;

   Abstract : In the late 1970s the city of Göteborg was faced with massive job loss as well as an empty urban waterfront (Norra Älvstranden) due to the closing down of the shipyards. Since then Göteborg has been struggling to transform itself into a successful post-industrial city. READ MORE
