  1. 11. Two-Dimensional Radiation Field Map of a Be-based Source

    University essay from Lunds universitet/Kärnfysik; Lunds universitet/Fysiska institutionen

    Author : Henrik Söderhielm; [2017]
    Keywords : Nuclear Physics Particle Detectors Neutrons Gamma Rays European Spallation Source Lund University; Physics and Astronomy;

    Abstract : The aim of this project was to measure the profile of the radiation exiting an aperture of the Aquarium at the Source Testing Facility at the Division of Nuclear Physics at Lund University. So far, the outgoing beam of radiation at the aperture of the Aquarium has been assumed to be uniform. READ MORE

  3. 12. Preparation, characterization and testing of model catalysts for CO oxidation and CO2 hydrogenation

    University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Synkrotronljusfysik

    Author : Stefano Albertin; [2017]
    Keywords : Surface science; Rhodium; Nanoparticles; Catalysis; CO2; Physics and Astronomy;

    Abstract : A joint research between Lund University and Chalmers Competence Centre for Catalysis have shown promising results for a Rh-based catalyst for CO2 hydrogenation catalytic applications. The original catalyst consisted of a dispersion of nanoparticles onto a porous 3D oxide network. READ MORE

  4. 13. Fabrication and Characterization of Bulk Nanostructured Cobalt Antimonide based Skutterudites Materials for Thermoelectric Applications.

    University essay from KTH/Material- och nanofysik

    Author : Mohammed Amin Hossain; [2015]
    Keywords : Thermoelectric; Bulk nanostructured; Skutterudites; Cobalt Antimonide; Ball milling; Spark Plasma Sintering;

    Abstract : The increasing price of oil, global warming and rapid industrial growth has drawn much attention to renewable energy technologies over the last few decades. The total energy consumption is estimated to increase 1.4% per year globally. About 90% of this energy supply is generated through fossil fuel combustion with a typical efficiency of 30-40%.

  5. 14. The Radiological Footprint of a Be-based Neutron Source

    University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Kärnfysik

    Author : Sharareh Koufigar; [2015]
    Keywords : Physics and Astronomy;

    Abstract : The radiological footprint of a Be-based neutron source embedded within the Aquarium of the Source-Testing Facility (STF) at the Division of Nuclear Physics at Lund University will soon be carefully mapped. As a precursor to this measurement program, neutron and gamma-ray energy spectra at beamport apertures have been measured using 3He and LaBr3(Ce) (cerium-activated lanthanum bromide) detectors.

  6. 15. Saturation Intensity of Rare Earth Ions Doped Crystals

    University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Atomfysik

    Author : Martynas Solovejus; [2014]
    Keywords : saturation intensity; spectral broadening; spectral effects; rare earths; rare-earths; cerium; Ce; Ce:YSO; Pr:YSO; RE:YSO; quantum information; quantum computing; Physics and Astronomy;

    Abstract : The thesis is primarily concerned with rare earth ions doped into yttrium ortho silicate crystals, RE:YSO. It is considered to be an ambitious platform for the development of quantum computing schemes. One such scheme requires the detection of single cerium ions. READ MORE
