  2. 6. Time-resolved CVD of Group 13-Nitrides

    Author : Polla Rouf; Henrik Pedersen; Urban Forsberg; Nathan O´brien; Ola Nilsen; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Group 13 nitrides (AlN, GaN and InN) and their alloys are semiconductor materials with a wide bandgap span covering from UV down to IR range. Their excellent electronic properties make them extremely attractive materials for light emitting diodes (LEDs) and different kind of transistor structures, especially high electron mobility transistors (HEMTs).

  4. 7. Pedestal structure and stability in JET-ILW and comparison with JET-C

    Author : Estera Stefanikova; Lorenzo Frassinetti; Per Brunsell; Joelle Mailloux; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; JET; Thomson scattering; pedestal; pedestal position; pedestal stability; Europed modelling; Physics; Fysik;

    Abstract : Controlled thermonuclear fusion offers a promising concept for safe and sustainable production of electrical energy. However, there are still many issues to be investigated on the way to a commercial fusion reactor. An important point for detailed studies is connected to wall materials surrounding hot thermonuclear plasma. READ MORE

  5. 8. On Fuel Coolant Interactions and Debris Coolability in Light Water Reactors

    Author : Sachin Thakre; Weimin Ma; Florian Fichot; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; severe accident; fuel-coolant interactions; melt jet fragmentation; steam explosion; debris bed coolability; uncertainty analysis; Energiteknik; Energy Technology;

    Abstract : During the case of a hypothetical severe accident in a light water reactor, core damage may occur and molten fuel may interact with water resulting in explosive interactions. A Fuel-Coolant Interactions (FCI) consists of many complex phenomena whose characteristics determine the energetics of the interactions. READ MORE

  6. 9. Neutron monitoring based on the higher order statistics of fission chamber signals

    Author : Zsolt Elter; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Campbelling mode; Filtered Poisson process; High order; Simulation; Neutron flux monitoring; Experiment; Fission chamber;

    Abstract : The work in this thesis corresponds to the safety aspect of Generation IV nuclear systems. One of the safety aspects concerns the enhancement of the performance of the in-vessel on-line core monitoring with neutron flux measurements. READ MORE

  7. 10. An Experimental Study of Fluid Dynamics and Mixing in Bubbly Gas-Liquid Flow Systems

    Author : Jafar Sadegh Moghaddas; Livsmedelsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Bubbly flow; PLIF; Two-phase flow; PIV; Gases; plasmas; Gaser; fluid dynamics; fluiddynamik; plasma; Mixing;

    Abstract : In the present project, a new experimental method enabling Planar Laser-Induced Fluorescence (PLIF) measurements in bubbly gas-liquid flows is presented. Due to reflection and refraction of the laser light, the bubbles will cause an uneven and unknown distribution of light intensity in the measurement plane. READ MORE
